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.
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.
The documentation is available on Gitbook and built from the libsodium-doc repository:
- offline documentation in PDF, MOBI and ePUB formats.
The integrity checking instructions (including the signing key for libsodium) are available in the installation section of the documentation.
