Description

Scrypt key derivation function as defined in Colin Percival's paper "Stronger Key Derivation via Sequential Memory-Hard Functions" http://www.tarsnap.com/scrypt/scrypt.pdf.

Synopsis

data Parameters = Parameters {
- n :: Word64
- r :: Int
- p :: Int
- outputLength :: Int
}
generate :: (ByteArrayAccess password, ByteArrayAccess salt, ByteArray output) => Parameters -> password -> salt -> output
