Crypto.SRP.Hashing
Description
Provides the KnownAlgorithm abstraction over SHA1, SHA256, SHA384 and SHA512,
together with the SRP-specific hash combinators (calcK, calcClientX,
calcXorHashnHashg) that implement the intermediate steps from
RFC 5054 ยง2.6.
Synopsis
- data KnownAlgorithm

- hashText :: KnownAlgorithm -> Text -> ByteString
- calcK :: KnownAlgorithm -> PrimeGroup -> ByteString
- calcClientX :: (Text, Text) -> ByteString -> KnownAlgorithm -> ByteString
- calcXorHashnHashg :: KnownAlgorithm -> PrimeGroup -> ByteString
