HMAC for Game Maker Language
A couple of scripts related to creating a HMAC (hash-based message authentication code).
Wikipedia Explaination: https://en.wikipedia.org/wiki/HMAC.
If you would like to help implement buffer_hmac_sha256 and buffer_hmac_sha512 scripts, I'd happily put them into the Github repository here:
A user on the YoYoGames Forums has a HMAC-SHA512 implementation here, however it might require some effort to port it / test it. https://forum.yoyogames.com/index.php?threads/solved-sha512-hmac-script.31253/
scr_juju_hmac_sha1_no_dependencies(key, string) script to use as an example.
