Sodium is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
It is a portable, cross-compilable, installable, packageable fork of NaCl, with a compatible API, and an extended API to improve usability even further.
Its goal is to provide all of the core operations needed to build higher-level cryptographic tools.
Sodium supports a variety of compilers and operating systems, including Windows (with MinGW or Visual Studio, x86 and x86_64), iOS and Android.
The design choices emphasize security, and “magic constants” have clear rationales.
And despite the emphasis on high security, primitives are faster across-the-board than most implementations of the NIST standards.
Version 1.0.11 was released on Jul 31, 2016.
