Compute MD5 message digests in Elm.

This is a fork of truqu/elm-md5 (the maintained fork of sanichi/elm-md5 focusing on performance), adding hexInOctets.

Quick Start

This library exposes just two functions, hex, which takes a String input and returns the 128-bit MD5 digest as a String of 32 hexadecimal characters, and hexInOctets, which instead returns the 128-bit MD5 digest as a List of 16 Ints between 0 and 15.

MD5.hex ""          == "d41d8cd98f00b204e9800998ecf8427e"
MD5.hex "foobarbaz" == "6df23dc03f9b54cc38a0fc1483df6e21"
MD5.hexInOctets "hello world" ==
    [ 0x5e , 0xb6 , 0x3b , 0xbb
    , 0xe0 , 0x1e , 0xee , 0xd0
    , 0x93 , 0xcb , 0x22 , 0xbb
    , 0x8f , 0x5a , 0xcd , 0xc3
    ]

Unlike the JavaScript function from which this implementation has been ported, CRLF pairs in the input are not automatically replaced with LFs prior to computing the digest. If you want that behaviour, adjust the input before evaluating the function. For example:

myHex : String -> String
myHex input =
    let
        myInput =
            Regex.replace Regex.All (Regex.regex "\x0D\n") (\_ -> "\n") input
    in
        MD5.hex myInput
