datadata Parameters

Parameters for Scrypt

Constructors

Parameters
- n :: Word64
  Cpu/Memory cost ratio. must be a power of 2 greater than 1. also known as N.
- r :: Int
  Must satisfy r * p < 2^30
- p :: Int
  Must satisfy r * p < 2^30
- outputLength :: Int
  the number of bytes to generate out of Scrypt

valuegenerate

:: (ByteArrayAccess password, ByteArrayAccess salt, ByteArray output)
=> Parameters
-> password
-> salt
-> output

Generate the scrypt key derivation data

Parameters the implementation refuses raise a CryptoError; tryGenerate reports the same condition as CryptoFailed.

valuetryGenerate

:: (ByteArrayAccess password, ByteArrayAccess salt, ByteArray output)
=> Parameters
-> password
-> salt
-> CryptoFailable output

Generate the scrypt key derivation data, reporting parameters the implementation refuses rather than raising.

n has to be a power of two, and r times p has to stay below 2^30.
