# Documentation

sha256 :: (Bits a, Integral a) => [a] -> Hash256 Source

`sha256` currently requires that the bitSize of `a` divide 32

sha256Ascii :: String -> Hash256 Source

`shaXXXAscii` assumes that all characters of the strings are ISO-latin-1 characters. ie. each characters fits in one octet.

type Hash256 = Hash8 Word32 Source

sha512 :: (Bits a, Integral a) => [a] -> Hash512 Source

`sha384` currently requires that the bitSize of `a` divide 64

sha512Ascii :: String -> Hash512 Source

type Hash512 = Hash8 Word64 Source

sha384 :: (Bits a, Integral a) => [a] -> Hash384 Source

`sha384` currently requires that the bitSize of `a` divide 64

sha384Ascii :: String -> Hash384 Source

sha224 :: (Bits a, Integral a) => [a] -> Hash224 Source

`sha224` currently requires that the bitSize of `a` divide 32
