An interface to message digest algorithms.

Documentation

data Digest

Digest is an opaque object that represents an algorithm of message digest.

getDigestByName :: String -> IO (Maybe Digest)

getDigestByName name returns a message digest algorithm whose name is name. If no algorithms are found, the result is Nothing.

getDigestNames :: IO [String]

getDigestNames returns a list of name of message digest algorithms.

digest :: Digest -> String -> String

Deprecated: Use digestBS or digestLBS instead.

digest digests a stream of data. The string must not contain any letters which aren't in the range of U+0000 - U+00FF.

digestBS :: Digest -> ByteString -> ByteString

digestBS digests a chunk of data.

digestLBS :: Digest -> ByteString -> ByteString

digestLBS digests a stream of data.

hmacBS

Arguments

:: Digest

the hash function to use in the HMAC calculation

-> ByteString

-> ByteString

resulting HMAC

Perform a private key signing using the HMAC template with a given hash

hmacLBS :: Digest -> ByteString -> ByteString -> ByteString

pkcs5_pbkdf2_hmac_sha1

Arguments

:: ByteString

password

-> ByteString

salt

-> Int

iterations

-> Int

destination key length

-> ByteString

destination key

Calculate a PKCS5-PBKDF2 SHA1-HMAC suitable for password hashing.
