Specifies the encryption context that will be used to encrypt the data. An encryption context is valid only for cryptographic operations with a symmetric KMS key. The standard asymmetric encryption algorithms that KMS uses do not support an encryption context.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric KMS key, but it is highly recommended.

For more information, see Encryption Context in the Key Management Service Developer Guide.

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and Using a grant token in the Key Management Service Developer Guide.

Specifies the encryption algorithm that KMS will use to encrypt the plaintext message. The algorithm must be compatible with the KMS key that you specify.

This parameter is required only for asymmetric KMS keys. The default value, SYMMETRIC_DEFAULT, is the algorithm used for symmetric KMS keys. If you are using an asymmetric KMS key, we recommend RSAES_OAEP_SHA_256.

Identifies the KMS key to use in the encryption operation.

To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
• Alias name: alias/ExampleAlias
• Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Returns only the grant with the specified grant ID. The grant ID uniquely identifies the grant.

Returns only grants where the specified principal is the grantee principal for the grant.

Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.

Use this parameter to specify the maximum number of items to return. When this value is present, KMS does not return more than the specified number of items, but it might return fewer.

This value is optional. If you include a value, it must be between 1 and 100, inclusive. If you do not include a value, it defaults to 50.

Returns only grants for the specified KMS key. This parameter is required.

Specify the key ID or key ARN of the KMS key. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN.

For example:

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

Tells KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST.

Use the DIGEST value only when the value of the Message parameter is a message digest. If you use the DIGEST value with a raw message, the security of the verification operation can be compromised.

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and Using a grant token in the Key Management Service Developer Guide.

Identifies the asymmetric KMS key that will be used to verify the signature. This must be the same KMS key that was used to generate the signature. If you specify a different KMS key, the signature verification fails.

To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

Specifies the message that was signed. You can submit a raw message of up to 4096 bytes, or a hash digest of the message. If you submit a digest, use the MessageType parameter with a value of DIGEST.

If the message specified here is different from the message that was signed, the signature verification fails. A message and its hash digest are considered to be the same message.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The signature that the Sign operation generated.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The length of the data key. Use AES_128 to generate a 128-bit symmetric key, or AES_256 to generate a 256-bit symmetric key.

Specifies the encryption context that will be used when encrypting the data key.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric KMS key, but it is highly recommended.

For more information, see Encryption Context in the Key Management Service Developer Guide.

The length of the data key in bytes. For example, use the value 64 to generate a 512-bit data key (64 bytes is 512 bits). For common key lengths (128-bit and 256-bit symmetric keys), we recommend that you use the KeySpec field instead of this one.

The AliasName value must be string of 1-256 characters. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/. The alias/aws/ prefix is reserved for Amazon Web Services managed keys.

Associates the alias with the specified customer managed key. The KMS key must be in the same Amazon Web Services Region.

A valid key ID is required. If you supply a null or empty string value, this operation returns an error.

For help finding the key ID and ARN, see Finding the Key ID and ARN in the /Key Management Service Developer Guide/ .

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

The principal that has permission to use the RetireGrant operation to retire the grant.

To specify the principal, use the Amazon Resource Name (ARN) of an Amazon Web Services principal. Valid Amazon Web Services principals include Amazon Web Services accounts (root), IAM users, federated users, and assumed role users. For examples of the ARN syntax to use for specifying a principal, see Amazon Web Services Identity and Access Management (IAM) in the Example ARNs section of the /Amazon Web Services General Reference/.

The grant determines the retiring principal. Other principals might have permission to retire the grant or revoke the grant. For details, see RevokeGrant and Retiring and revoking grants in the Key Management Service Developer Guide.

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and Using a grant token in the Key Management Service Developer Guide.

Specifies a grant constraint.

KMS supports the EncryptionContextEquals and EncryptionContextSubset grant constraints. Each constraint value can include up to 8 encryption context pairs. The encryption context value in each constraint cannot exceed 384 characters.

These grant constraints allow the permissions in the grant only when the encryption context in the request matches (EncryptionContextEquals) or includes (EncryptionContextSubset) the encryption context specified in this structure. For information about grant constraints, see Using grant constraints in the Key Management Service Developer Guide. For more information about encryption context, see Encryption Context in the /Key Management Service Developer Guide/ .

The encryption context grant constraints are supported only on operations that include an encryption context. You cannot use an encryption context grant constraint for cryptographic operations with asymmetric KMS keys or for management operations, such as DescribeKey or RetireGrant.

A friendly name for the grant. Use this value to prevent the unintended creation of duplicate grants when retrying this request.

When this value is absent, all CreateGrant requests result in a new grant with a unique GrantId even if all the supplied parameters are identical. This can result in unintended duplicates when you retry the CreateGrant request.

When this value is present, you can retry a CreateGrant request with identical parameters; if the grant already exists, the original GrantId is returned without creating a new grant. Note that the returned grant token is unique with every CreateGrant request, even when a duplicate GrantId is returned. All grant tokens for the same grant ID can be used interchangeably.

Identifies the KMS key for the grant. The grant gives principals permission to use this KMS key.

Specify the key ID or key ARN of the KMS key. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

The identity that gets the permissions specified in the grant.

To specify the principal, use the Amazon Resource Name (ARN) of an Amazon Web Services principal. Valid Amazon Web Services principals include Amazon Web Services accounts (root), IAM users, IAM roles, federated users, and assumed role users. For examples of the ARN syntax to use for specifying a principal, see Amazon Web Services Identity and Access Management (IAM) in the Example ARNs section of the /Amazon Web Services General Reference/.

A list of operations that the grant permits.

The operation must be supported on the KMS key. For example, you cannot create a grant for a symmetric KMS key that allows the Sign operation, or a grant for an asymmetric KMS key that allows the GenerateDataKey operation. If you try, KMS returns a ValidationError exception. For details, see Grant operations in the Key Management Service Developer Guide.

The unique identifier for the grant.

You can use the GrantId in a ListGrants, RetireGrant, or RevokeGrant operation.

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
• Alias name: alias/ExampleAlias
• Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

The type of the of the public key that was downloaded.

The Amazon Resource Name (key ARN) of the asymmetric KMS key from which the public key was downloaded.

Instead, use the KeySpec field in the GetPublicKey response.

The KeySpec and CustomerMasterKeySpec fields have the same value. We recommend that you use the KeySpec field in your code. However, to avoid breaking changes, KMS will support both fields.

The encryption algorithms that KMS supports for this key.

This information is critical. If a public key encrypts data outside of KMS by using an unsupported encryption algorithm, the ciphertext cannot be decrypted.

This field appears in the response only when the KeyUsage of the public key is ENCRYPT_DECRYPT.

The exported public key.

The value is a DER-encoded X.509 public key, also known as SubjectPublicKeyInfo (SPKI), as defined in RFC 5280. When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The signing algorithms that KMS supports for this key.

This field appears in the response only when the KeyUsage of the public key is SIGN_VERIFY.

The permitted use of the public key. Valid values are ENCRYPT_DECRYPT or SIGN_VERIFY.

This information is critical. If a public key with SIGN_VERIFY key usage encrypts data outside of KMS, the ciphertext cannot be decrypted.

The response's http status code.

The length of the byte string.

Generates the random byte string in the CloudHSM cluster that is associated with the specified custom key store. To find the ID of a custom key store, use the DescribeCustomKeyStores operation.

The random byte string. When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The response's http status code.

The source of the key material for the KMS key. You cannot change the origin after you create the KMS key. The default is AWS_KMS, which means that KMS creates the key material.

To create a KMS key with no key material (for imported key material), set the value to EXTERNAL. For more information about importing key material into KMS, see Importing Key Material in the Key Management Service Developer Guide. This value is valid only for symmetric KMS keys.

To create a KMS key in an KMS custom key store and create its key material in the associated CloudHSM cluster, set this value to AWS_CLOUDHSM. You must also use the CustomKeyStoreId parameter to identify the custom key store. This value is valid only for symmetric KMS keys.

Specifies the type of KMS key to create. The default value, SYMMETRIC_DEFAULT, creates a KMS key with a 256-bit symmetric key for encryption and decryption. For help choosing a key spec for your KMS key, see How to Choose Your KMS key Configuration in the /Key Management Service Developer Guide/ .

The KeySpec determines whether the KMS key contains a symmetric key or an asymmetric key pair. It also determines the encryption algorithms or signing algorithms that the KMS key supports. You can't change the KeySpec after the KMS key is created. To further restrict the algorithms that can be used with the KMS key, use a condition key in its key policy or IAM policy. For more information, see kms:EncryptionAlgorithm or kms:Signing Algorithm in the /Key Management Service Developer Guide/ .

Amazon Web Services services that are integrated with KMS use symmetric KMS keys to protect your data. These services do not support asymmetric KMS keys. For help determining whether a KMS key is symmetric or asymmetric, see Identifying Symmetric and Asymmetric KMS keys in the Key Management Service Developer Guide.

KMS supports the following key specs for KMS keys:

• Symmetric key (default)

  • SYMMETRIC_DEFAULT (AES-256-GCM)

• Asymmetric RSA key pairs

  • RSA_2048

  • RSA_3072

  • RSA_4096

• Asymmetric NIST-recommended elliptic curve key pairs

  • ECC_NIST_P256 (secp256r1)
  • ECC_NIST_P384 (secp384r1)
  • ECC_NIST_P521 (secp521r1)

• Other asymmetric elliptic curve key pairs

  • ECC_SECG_P256K1 (secp256k1), commonly used for cryptocurrencies.

Instead, use the KeySpec parameter.

The KeySpec and CustomerMasterKeySpec parameters work the same way. Only the names differ. We recommend that you use KeySpec parameter in your code. However, to avoid breaking changes, KMS will support both parameters.

Determines the cryptographic operations for which you can use the KMS key. The default value is ENCRYPT_DECRYPT. This parameter is required only for asymmetric KMS keys. You can't change the KeyUsage value after the KMS key is created.

Select only one valid value.

• For symmetric KMS keys, omit the parameter or specify ENCRYPT_DECRYPT.
• For asymmetric KMS keys with RSA key material, specify ENCRYPT_DECRYPT or SIGN_VERIFY.
• For asymmetric KMS keys with ECC key material, specify SIGN_VERIFY.

A flag to indicate whether to bypass the key policy lockout safety check.

Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.

For more information, refer to the scenario in the Default Key Policy section in the /Key Management Service Developer Guide/ .

Use this parameter only when you include a policy in the request and you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.

The default value is false.

The key policy to attach to the KMS key.

If you provide a key policy, it must meet the following criteria:

• If you don't set BypassPolicyLockoutSafetyCheck to true, the key policy must allow the principal that is making the CreateKey request to make a subsequent PutKeyPolicy request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section of the /Key Management Service Developer Guide/ .
• Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal (for example, an IAM user or role), you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see Changes that I make are not always immediately visible in the /Amazon Web Services Identity and Access Management User Guide/.

If you do not provide a key policy, KMS attaches a default key policy to the KMS key. For more information, see Default Key Policy in the Key Management Service Developer Guide.

The key policy size quota is 32 kilobytes (32768 bytes).

For help writing and formatting a JSON policy document, see the IAM JSON Policy Reference in the /Identity and Access Management User Guide/ .

A description of the KMS key.

Use a description that helps you decide whether the KMS key is appropriate for a task. The default value is an empty string (no description).

To set or change the description after the key is created, use UpdateKeyDescription.

Creates the KMS key in the specified custom key store and the key material in its associated CloudHSM cluster. To create a KMS key in a custom key store, you must also specify the Origin parameter with a value of AWS_CLOUDHSM. The CloudHSM cluster that is associated with the custom key store must have at least two active HSMs, each in a different Availability Zone in the Region.

This parameter is valid only for symmetric KMS keys and regional KMS keys. You cannot create an asymmetric KMS key or a multi-Region key in a custom key store.

To find the ID of a custom key store, use the DescribeCustomKeyStores operation.

The response includes the custom key store ID and the ID of the CloudHSM cluster.

This operation is part of the Custom Key Store feature feature in KMS, which combines the convenience and extensive integration of KMS with the isolation and control of a single-tenant key store.

Assigns one or more tags to the KMS key. Use this parameter to tag the KMS key when it is created. To tag an existing KMS key, use the TagResource operation.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see Using ABAC in KMS in the Key Management Service Developer Guide.

To use this parameter, you must have kms:TagResource permission in an IAM policy.

Each tag consists of a tag key and a tag value. Both the tag key and the tag value are required, but the tag value can be an empty (null) string. You cannot have more than one tag on a KMS key with the same tag key. If you specify an existing tag key with a different tag value, KMS replaces the current tag value with the specified one.

When you add tags to an Amazon Web Services resource, Amazon Web Services generates a cost allocation report with usage and costs aggregated by tags. Tags can also be used to control access to a KMS key. For details, see Tagging Keys.

Creates a multi-Region primary key that you can replicate into other Amazon Web Services Regions. You cannot change this value after you create the KMS key.

For a multi-Region key, set this parameter to True. For a single-Region KMS key, omit this parameter or set it to False. The default value is False.

This operation supports multi-Region keys, an KMS feature that lets you create multiple interoperable KMS keys in different Amazon Web Services Regions. Because these KMS keys have the same key ID, key material, and other metadata, you can use them interchangeably to encrypt data in one Amazon Web Services Region and decrypt it in a different Amazon Web Services Region without re-encrypting the data or making a cross-Region call. For more information about multi-Region keys, see Using multi-Region keys in the Key Management Service Developer Guide.

This value creates a primary key, not a replica. To create a /replica key/, use the ReplicateKey operation.

You can create a symmetric or asymmetric multi-Region key, and you can create a multi-Region key with imported key material. However, you cannot create a multi-Region key in a custom key store.

Specifies the length of the data key. Use AES_128 to generate a 128-bit symmetric key, or AES_256 to generate a 256-bit symmetric key.

You must specify either the KeySpec or the NumberOfBytes parameter (but not both) in every GenerateDataKey request.

Specifies the encryption context that will be used when encrypting the data key.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric KMS key, but it is highly recommended.

For more information, see Encryption Context in the Key Management Service Developer Guide.

Specifies the length of the data key in bytes. For example, use the value 64 to generate a 512-bit data key (64 bytes is 512 bits). For 128-bit (16-byte) and 256-bit (32-byte) data keys, use the KeySpec parameter.

You must specify either the KeySpec or the NumberOfBytes parameter (but not both) in every GenerateDataKey request.

Identifies the alias that is changing its KMS key. This value must begin with alias/ followed by the alias name, such as alias/ExampleAlias. You cannot use UpdateAlias to change the alias name.

Identifies the customer managed key to associate with the alias. You don't have permission to associate an alias with an Amazon Web Services managed key.

The KMS key must be in the same Amazon Web Services account and Region as the alias. Also, the new target KMS key must be the same type as the current target KMS key (both symmetric or both asymmetric) and they must have the same key usage.

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

Specifies the KMS key that KMS uses to decrypt the ciphertext. Enter a key ID of the KMS key that was used to encrypt the ciphertext.

This parameter is required only when the ciphertext was encrypted under an asymmetric KMS key. If you used a symmetric KMS key, KMS can get the KMS key from metadata that it adds to the symmetric ciphertext blob. However, it is always recommended as a best practice. This practice ensures that you use the KMS key that you intend.

To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and Using a grant token in the Key Management Service Developer Guide.

Identifies an asymmetric KMS key. KMS uses the private key in the asymmetric KMS key to sign the message. The KeyUsage type of the KMS key must be SIGN_VERIFY. To find the KeyUsage of a KMS key, use the DescribeKey operation.

To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

For example:

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Specifies the message or message digest to sign. Messages can be 0-4096 bytes. To sign a larger message, provide the message digest.

If you provide a message, KMS generates a hash digest of the message and then signs it.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

Specifies the signing algorithm to use when signing the message.

Choose an algorithm that is compatible with the type and size of the specified asymmetric KMS key.

The signing algorithm that was used to sign the message.

The cryptographic signature that was generated for the message.

• When used with the supported RSA signing algorithms, the encoding of this value is defined by PKCS #1 in RFC 8017.
• When used with the ECDSA_SHA_256, ECDSA_SHA_384, or ECDSA_SHA_512 signing algorithms, this value is a DER-encoded object as defined by ANS X9.62–2005 and RFC 3279 Section 2.2.3. This is the most commonly used signature format and is appropriate for most uses.

When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The Amazon Resource Name (key ARN) of the asymmetric KMS key that was used to sign the message.

The response's http status code.

The waiting period, specified in number of days. After the waiting period ends, KMS deletes the KMS key.

If the KMS key is a multi-Region primary key with replicas, the waiting period begins when the last of its replica keys is deleted. Otherwise, the waiting period begins immediately.

This value is optional. If you include a value, it must be between 7 and 30, inclusive. If you do not include a value, it defaults to 30.

The unique identifier of the KMS key to delete.

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

The Amazon Resource Name (key ARN) of the KMS key whose deletion is scheduled.

The current status of the KMS key.

For more information about how key state affects the use of a KMS key, see Key state: Effect on your KMS key in the Key Management Service Developer Guide.

The date and time after which KMS deletes the KMS key.

If the KMS key is a multi-Region primary key with replica keys, this field does not appear. The deletion date for the primary key isn't known until its last replica key is deleted.

The waiting period before the KMS key is deleted.

If the KMS key is a multi-Region primary key with replicas, the waiting period begins when the last of its replica keys is deleted. Otherwise, the waiting period begins immediately.

The response's http status code.

Specifies the encryption context that will be used when encrypting the private key in the data key pair.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric KMS key, but it is highly recommended.

For more information, see Encryption Context in the Key Management Service Developer Guide.

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token and Using a grant token in the Key Management Service Developer Guide.

Specifies the symmetric KMS key that encrypts the private key in the data key pair. You cannot specify an asymmetric KMS key or a KMS key in a custom key store. To get the type and origin of your KMS key, use the DescribeKey operation.

To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Determines the type of data key pair that is generated.

The KMS rule that restricts the use of asymmetric RSA KMS keys to encrypt and decrypt or to sign and verify (but not both), and the rule that permits you to use ECC KMS keys only to sign and verify, are not effective on data key pairs, which are used outside of KMS.

The Amazon Resource Name (key ARN) of the KMS key that encrypted the private key.

The public key (in plaintext).-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The plaintext copy of the private key. When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The type of data key pair that was generated.

The encrypted copy of the private key. When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded.

The response's http status code.

A flag to indicate whether to bypass the key policy lockout safety check.

Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.

For more information, refer to the scenario in the Default Key Policy section in the Key Management Service Developer Guide.

Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.

The default value is false.

The key policy to attach to the KMS key. This parameter is optional. If you do not provide a key policy, KMS attaches the default key policy to the KMS key.

The key policy is not a shared property of multi-Region keys. You can specify the same key policy or a different key policy for each key in a set of related multi-Region keys. KMS does not synchronize this property.

If you provide a key policy, it must meet the following criteria:

• If you don't set BypassPolicyLockoutSafetyCheck to true, the key policy must give the caller kms:PutKeyPolicy permission on the replica key. This reduces the risk that the KMS key becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section of the /Key Management Service Developer Guide/ .
• Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal (for example, an IAM user or role), you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see Changes that I make are not always immediately visible in the /Identity and Access Management User Guide/ .
• The key policy size quota is 32 kilobytes (32768 bytes).

A description of the KMS key. The default value is an empty string (no description).

The description is not a shared property of multi-Region keys. You can specify the same description or a different description for each key in a set of related multi-Region keys. KMS does not synchronize this property.

Assigns one or more tags to the replica key. Use this parameter to tag the KMS key when it is created. To tag an existing KMS key, use the TagResource operation.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see Using ABAC in KMS in the Key Management Service Developer Guide.

To use this parameter, you must have kms:TagResource permission in an IAM policy.

Tags are not a shared property of multi-Region keys. You can specify the same tags or different tags for each key in a set of related multi-Region keys. KMS does not synchronize this property.

Each tag consists of a tag key and a tag value. Both the tag key and the tag value are required, but the tag value can be an empty (null) string. You cannot have more than one tag on a KMS key with the same tag key. If you specify an existing tag key with a different tag value, KMS replaces the current tag value with the specified one.

When you add tags to an Amazon Web Services resource, Amazon Web Services generates a cost allocation report with usage and costs aggregated by tags. Tags can also be used to control access to a KMS key. For details, see Tagging Keys.

Identifies the multi-Region primary key that is being replicated. To determine whether a KMS key is a multi-Region primary key, use the DescribeKey operation to check the value of the MultiRegionKeyType property.

Specify the key ID or key ARN of a multi-Region primary key.

For example:

• Key ID: mrk-1234abcd12ab34cd56ef1234567890ab
• Key ARN: arn:aws:kms:us-east-2:111122223333:key/mrk-1234abcd12ab34cd56ef1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

The Region ID of the Amazon Web Services Region for this replica key.

Enter the Region ID, such as us-east-1 or ap-southeast-2. For a list of Amazon Web Services Regions in which KMS is supported, see KMS service endpoints in the Amazon Web Services General Reference.

The replica must be in a different Amazon Web Services Region than its primary key and other replicas of that primary key, but in the same Amazon Web Services partition. KMS must be available in the replica Region. If the Region is not enabled by default, the Amazon Web Services account must be enabled in the Region.

For information about Amazon Web Services partitions, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference. For information about enabling and disabling Regions, see Enabling a Region and Disabling a Region in the Amazon Web Services General Reference.

Displays details about the new replica key, including its Amazon Resource Name (key ARN) and key state. It also includes the ARN and Amazon Web Services Region of its primary key and other replica keys.

The key policy of the new replica key. The value is a key policy document in JSON format.

The tags on the new replica key. The value is a list of tag key and tag value pairs.

The response's http status code.

A flag to indicate whether to bypass the key policy lockout safety check.

Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately.

For more information, refer to the scenario in the Default Key Policy section in the Key Management Service Developer Guide.

Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

The name of the key policy. The only valid value is default.

The key policy to attach to the KMS key.

The key policy must meet the following criteria:

• If you don't set BypassPolicyLockoutSafetyCheck to true, the key policy must allow the principal that is making the PutKeyPolicy request to make a subsequent PutKeyPolicy request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section of the Key Management Service Developer Guide.
• Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal (for example, an IAM user or role), you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see Changes that I make are not always immediately visible in the /Amazon Web Services Identity and Access Management User Guide/.

The key policy cannot exceed 32 kilobytes (32768 bytes). For more information, see Resource Quotas in the Key Management Service Developer Guide.

String that contains the key ARN.

The user-specified friendly name for the custom key store.

The trust anchor certificate of the associated CloudHSM cluster. When you initialize the cluster, you create this certificate and save it in the customerCA.crt file.

Describes the connection error. This field appears in the response only when the ConnectionState is FAILED. For help resolving these errors, see How to Fix a Connection Failure in Key Management Service Developer Guide.

Valid values are:

• CLUSTER_NOT_FOUND - KMS cannot find the CloudHSM cluster with the specified cluster ID.
• INSUFFICIENT_CLOUDHSM_HSMS - The associated CloudHSM cluster does not contain any active HSMs. To connect a custom key store to its CloudHSM cluster, the cluster must contain at least one active HSM.
• INTERNAL_ERROR - KMS could not complete the request due to an internal error. Retry the request. For ConnectCustomKeyStore requests, disconnect the custom key store before trying to connect again.
• INVALID_CREDENTIALS - KMS does not have the correct password for the kmsuser crypto user in the CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the key store password value for the custom key store.
• NETWORK_ERRORS - Network errors are preventing KMS from connecting to the custom key store.
• SUBNET_NOT_FOUND - A subnet in the CloudHSM cluster configuration was deleted. If KMS cannot find all of the subnets in the cluster configuration, attempts to connect the custom key store to the CloudHSM cluster fail. To fix this error, create a cluster from a recent backup and associate it with your custom key store. (This process creates a new cluster configuration with a VPC and private subnets.) For details, see How to Fix a Connection Failure in the Key Management Service Developer Guide.
• USER_LOCKED_OUT - The kmsuser CU account is locked out of the associated CloudHSM cluster due to too many failed password attempts. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the key store password value for the custom key store.
• USER_LOGGED_IN - The kmsuser CU account is logged into the the associated CloudHSM cluster. This prevents KMS from rotating the kmsuser account password and logging into the cluster. Before you can connect your custom key store to its CloudHSM cluster, you must log the kmsuser CU out of the cluster. If you changed the kmsuser password to log into the cluster, you must also and update the key store password value for the custom key store. For help, see How to Log Out and Reconnect in the Key Management Service Developer Guide.
• USER_NOT_FOUND - KMS cannot find a kmsuser CU account in the associated CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must create a kmsuser CU account in the cluster, and then update the key store password value for the custom key store.

The date and time when the custom key store was created.

A unique identifier for the CloudHSM cluster that is associated with the custom key store.

A unique identifier for the custom key store.

Indicates whether the custom key store is connected to its CloudHSM cluster.

You can create and use KMS keys in your custom key stores only when its connection state is CONNECTED.

The value is DISCONNECTED if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If the value is CONNECTED but you are having trouble using the custom key store, make sure that its associated CloudHSM cluster is active and contains at least one active HSM.

A value of FAILED indicates that an attempt to connect was unsuccessful. The ConnectionErrorCode field in the response indicates the cause of the failure. For help resolving a connection failure, see Troubleshooting a Custom Key Store in the Key Management Service Developer Guide.
