Pure Lua implementation of md5

Question

Is there a pure lua implementation of the md5 hashing algorithm? One that doesn\'t rely on any c or external libraries? There\'s javascript implementations that don\'t rely

Answer 1

I've refined @Adam Baldwin's solution and made a library that calculates md5 sums in pure Lua, with no external dependencies and no C:

https://github.com/kikito/md5.lua

Summary of changes:

• Implemented two functions on the interface, md5.sum and md5.sumhex, that work exactly like their counterparts in the Kepler library, but are implemented in Lua alone.
• Added a small test suite with using busted.
• Removed some unused functions
• Avoided re-creation of anonymous functions when it was not needed
• Simplified the creation of the constants, and made them private
• Spacing and naming changes.

For now I don't need md5.crypt and md5.decrypt, so I have not implemented those. But I will accept pull requests :)
