NaCl: Networking and Cryptography library

by wabaus
NaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed.


Secure Salted Password Hashing - How to do it Properly

by Spone & 3 others, 2 comments
If you're a web developer, you've probably had to make a user account system. The most important aspect of a user account system is how user passwords are protected.

an interesting review of hash functions and their performance over different sets of keys. Note that he measure the actual time for hashing + scanning through a collision list rather than just counting the numbers of collisions.
