Crypto.KDF.PBKDF2

Password Based Key Derivation Function 2

typetype PRF password = password -> Bytes -> Bytes

The PRF used for PBKDF2

valueprfHMAC :: (HashAlgorithm a, ByteArrayAccess password) => a -> PRF password

PRF for PBKDF2 using HMAC with the hash algorithm as parameter

datadata Parameters

Parameters for PBKDF2

Parameters
- iterCounts :: Int
  the number of user-defined iterations for the algorithms. e.g. WPA2 uses 4000. (must be > 0)
- outputLength :: Int
  the number of bytes to generate out of PBKDF2 (must not be negative)

valuegenerate

generate the pbkdf2 key derivation function from the output

Parameters outside the ranges documented for Parameters raise CryptoError_ParameterInvalid; tryGenerate reports the same condition as CryptoFailed.

valuetryGenerate

generate the pbkdf2 key derivation function from the output, reporting parameters the implementation refuses rather than raising.

valuefastPBKDF2_SHA1

PBKDF2 with HMAC-SHA1, using the bundled C implementation.

Parameters outside the ranges documented for Parameters raise CryptoError_ParameterInvalid; tryFastPBKDF2_SHA1 reports the same condition as CryptoFailed.

valuetryFastPBKDF2_SHA1

PBKDF2 with HMAC-SHA1, reporting parameters the implementation refuses rather than raising.

valuefastPBKDF2_SHA256

PBKDF2 with HMAC-SHA256, using the bundled C implementation.

Parameters outside the ranges documented for Parameters raise CryptoError_ParameterInvalid; tryFastPBKDF2_SHA256 reports the same condition as CryptoFailed.

valuetryFastPBKDF2_SHA256

PBKDF2 with HMAC-SHA256, reporting parameters the implementation refuses rather than raising.

valuefastPBKDF2_SHA512

PBKDF2 with HMAC-SHA512, using the bundled C implementation.

Parameters outside the ranges documented for Parameters raise CryptoError_ParameterInvalid; tryFastPBKDF2_SHA512 reports the same condition as CryptoFailed.

valuetryFastPBKDF2_SHA512

PBKDF2 with HMAC-SHA512, reporting parameters the implementation refuses rather than raising.
