encodeBase16 :: Hash -> ByteString Source #

Produce a base16 (ascii-hex) encoded string from a hash. This can be turned back into a Hash (see "decodeBase16". This is a loss-less process.

decodeBase16 :: ByteString -> Hash Source #

Take a base16-encoded string and decode it as a Hash. If the string is malformed, yields NoHash.

sha256 :: ByteString -> Hash Source #

Compute a sha256 of a (lazy) ByteString.

sha256sum :: ByteString -> String Source #

Same as previous but general purpose.

rawHash :: Hash -> ByteString Source #

match :: Hash -> Hash -> Bool Source #
