Latest Projects
It seems like I've been working on so many random things the past few weeks. And all on different platforms: C (UNIX/POSIX), Python, Cocoa, iOS.
Anyhow, the only things that are almost ready for public consumption are the security-related libraries/modules. (Each succeeding project builds on the previous.) All are BSD licensed.
sha-asaddi
Everything SHA, from SHA-1 to SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512) to the newest truncated editions (SHA-512/224, SHA-512/256). Also includes HMAC wrappers for each. This is a cleaned up and refactored version of my previous command-line sha project. Still WIP though.
pbkdf2
Implementations of PBKDF2 in C and Python. The C version depends on sha-asaddi, though I suppose it can easily be swapped to use any other SHA/HMAC implementations with similar signatures. The Python version has no dependencies outside of the standard library.
scrypt
Implementations of Colin Percival's scrypt in C and pure Python. This was more of an academic exercise since Mr. Percival's version is far more optimized and is already available under a BSD license. (At least, I'm assuming it's more optimized — I haven't actually looked at his code yet. But he did seem to have assembly/SSE optimized versions.) The Python version is probably too slow to be practical. (A Python wrapper for the original scrypt implementation is already available.) Will gladly take optimization suggestions for the Python version!
Oh, and these three projects represent a general shift in my packaging/building ideals. For now, I've decided to ditch GNU's autotools in favor of CMake for my projects. CMake just seems like a more coherent tool for configuring/building in a platform-independent manner. But, that just, like, my opinion, man...
