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
