The time cost, which defines the amount of computation realized and therefore the execution time, given in number of iterations.

The memory cost, which defines the memory usage, given in kibibytes.

max ARGON2_MIN_MEMORY (8 * hashParallelism) <= hashMemory <= ARGON2_MAX_MEMORY

A parallelism degree, which defines the number of parallel threads.

Which variant of Argon2 to use. You should choose the variant that is most applicable to your intention to hash inputs.

Constructors

Argon2d	Argon2d is faster than Argon2i and uses data-depending memory access, which makes it suitable for cryptocurrencies and applications with no threats from side-channel timing attacks.
Argon2i	Argon2i uses data-independent memory access, which is preferred for password hashing and password-based key derivation. Argon2i is slower as it makes more passes over the memory to protect from tradeoff attacks.
Argon2id	Argon2id is a hybrid of Argon2i and Argon2d, using a combination of data-depending and data-independent memory accesses, which gives some of Argon2i's resistance to side-channel cache timing attacks and much of Argon2d's resistance to GPU cracking attacks
