Classes

class Hash h where

Typeclass for hashes.

Minimal complete definition

hashName, hashLength, hash, hashHKDF, hashBytesToCK, hashCKToBytes, hashToBytes

Associated Types

data ChainingKey h :: *

Represents a chaining key used as part of HKDF.

data Digest h :: *

Represents a hash digest.

Methods

hashName :: proxy h -> ScrubbedBytes

Returns the name of the hash. This is used when generating the handshake name.

hashLength :: proxy h -> Int

Returns the length of the hash output in bytes.

hash :: ScrubbedBytes -> Digest h

Hashes data.

hashHKDF :: ChainingKey h -> ScrubbedBytes -> (ChainingKey h, ScrubbedBytes)

Performs HKDF.

hashBytesToCK :: ScrubbedBytes -> ChainingKey h

Converts a series of bytes to a chaining key.

hashCKToBytes :: ChainingKey h -> ScrubbedBytes

Converts a chaining key to a series of bytes.

hashToBytes :: Digest h -> ScrubbedBytes

Converts a hash digest to a series of bytes.
