About jedisct1/libsodium

Libsodium is a modern, portable, easy-to-use software library that provides a wide range of cryptographic operations including encryption, decryption, digital signatures, and secure password hashing. It is a fork of NaCl that maintains API compatibility while extending functionality to improve usability and simplify secure application development. The library supports cross-platform environments including Windows (MinGW and Visual Studio, x86, x64, arm64), iOS, Android, JavaScript, and WebAssembly, and is designed to be cross-compilable, installable, and packageable. It uses a two-tier release system with point releases for new features and stable maintenance updates, and security fixes are immediately pushed to the stable branch. Licensed under the ISC license, libsodium is actively maintained with over 13,800 stars on GitHub and a community of contributors.
