MD5 hasher implemented in both ANSI C and Lua.

clownmd5

This is an MD5 hasher. Two versions are provided: one written in ANSI C, and another written in Lua. The C version is implemented as a single-header library. Both versions are licensed under the 0BSD licence.

I initially wrote the C version back when I was in university. I was meant to write it in C#, but I prefer C so I wrote the prototype in that instead and converted it to C# afterwards. The C# version is pretty redundant since the standard library already has an MD5 hasher, so I haven't included it in this repository. Way later, I stumbled across a copy of the C prototype and refactored it into a single-header library. I also overhauled the interface to be a lot more low-level, to eliminate overhead.

The Lua version was something that I created much more recently, just because a Lua script of mine needed a file hasher and none of the libraries that I could find were very fast. It's a straight port of the C version.
