util.hmac

Provides keyed hash functions. This library is actually a front for util.hashes

local hmac = require "util.hmac";
hmac.md5(key, string, hex);
hmac.sha1(key, string, hex);
hmac.sha256(key, string, hex);
hmac.sha512(key, string, hex);

All of the above functions return a hash string according to the chosen algorithm. By default the raw binary form is returned, most often you will want to pass true as the third parameter to get a nice hex-encoded string.
