I am looking for some open-sourced encryption libraries to be ported over to a different platform. The platform only has the libc library availible and it would require me to reimplement the algorithms in assembly language. Preferably ones that avoid floating-pointer operations (simply due the the MCUs limitations) and that you think would be easier to rewrite using a simple instruction set like PIC16F

I am looking for some basic functions like Hashing & public private key encryption.

Thanks.

I've used LibTomCrypt for AVR32. It's fast, it's small and it works :)

It is very uncommon for cryptographic libraries to make use of floating point.

PolarSSL is very clean, modular, written in C, with no external dependencies. It's easy to extract the routines you need.

Of course, bear in mind that it is GPLv2. A commercial license is available too though.

  • Thanks. I really appreciate your advice despite this question being closed, you have given me a good lead. I think I am gonig to go with LibTomCrypt just due to simplicity of legal issues its use of the WTFPL (Do what the f*** you want to public license.) Actually, I am not even joking, it uses this license xd – Jeremy Dec 12 '12 at 02:06
