Pure lua hashing, RIPEMD160 or SHA2?

Question

Are there any implementations of these hashing algorithms in pure lua? I've found a couple for MD5 and SHA1 but none for these two which are the ones I'll be needing for a project. In the interests of portability, I need something in pure lua. Anyone know of anything?

Lua's lmd5 library states: A message digest library for Lua based on OpenSSL. It supports MD2, MD4, MD5, SHA1, SHA2, RIPEMD160, MDC2. Though I have never used it. But there are some libraries listed here. You might one of them useful.

Here's another library which might be what you seek.

If its "based on OpenSSL", then its not in pure lua. (Unless based on means inspired by, or in the style of) – Michael Anderson Jun 23 '12 at 08:29

@MichaelAnderson I think [this one](http://lua-users.org/wiki/SecureHashAlgorithm)'s is pure lua implementation – hjpotter92 Jun 23 '12 at 08:33

If you use LuaJIT I have written an implementation of SHA256 here but it uses FFI ctypes: https://github.com/catwell/cw-lua/tree/master/sha256

Otherwise there's one here in pure Lua 5.2 which I have not tested: http://lua-users.org/wiki/SecureHashAlgorithm (already cited by Dream Eater).
