elm-md5

Compute MD5 message digests in Elm.

Quick Start

This library exposes just one function, hex, which takes a String input and returns the 128-bit MD5 digest as a String of 32 hexadecimal characters.

MD5.hex ""          == "d41d8cd98f00b204e9800998ecf8427e"
MD5.hex "foobarbaz" == "6df23dc03f9b54cc38a0fc1483df6e21"

Unlike the JavaScript program upon which this implementation is based, 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

Versioning

In the dependencies section of elm-package.json use the following. For Elm 0.17:

"sanichi/md5": "1.0.0 <= v < 1.0.1"

For Elm 0.18:

"sanichi/md5": "1.0.1 <= v < 2.0.0"

I would rather have bumped the version to 2.0.0 for the Elm 0.18 upgrade but the package publishing tools prevented this since the API had not changed.
