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 is cross-platforms and cross-languages. It runs on a variety of compilers and operating systems, including Windows (with MinGW or Visual Studio, x86 and x86_64), iOS and Android. Javascript and WebAssembly versions are also available and are fully supported. Bindings for all common programming languages are available and well-supported.
The design choices emphasize security and ease of use. But despite the emphasis on high security, primitives are faster across-the-board than most implementations.
