NaCl (pronounced "salt") is a new easy-to-use high-speed software library for 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, but NaCl improves security, improves usability, and improves speed. We’ll explain how the design and implementation of NaCl avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL.
This talk also presents TweetNaCl, a self-contained public-domain C library which reimplements the NaCl library in just 100 tweets. See https://twitter.com/tweetnacl.
