From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
Sodium is an 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 portable, cross-compilable, installable, and packageable fork of NaCl. While maintaining API compatibility, libsodium extends functionality to improve usability and simplify the development of secure applications. Key Features Encryption & Decryption: Securely encrypt and decrypt data with modern algorithms. Digital Signatures: Create and verify signatures to ensure data authenticity. Cross-Platform Compatibility: Supported on Windows (MinGW and Visual Studio, x86, x64 and arm64), iOS, Android, JavaScript, and WebAssembly. User-Friendly API: Designed to provide all core cryptographic operations while remaining easy to integrate into your projects. Documentation Installation Quickstart Full Documentation Releases Integrity Checking Versioning libsodium uses a two-tier release system: Point releases (e.g., 1.0.19, 1.0.20, 1.0.21) are tagged when new features are added or significant changes are made. Stable releases are frequent maintenance updates between point releases. They fix minor issues while remaining fully compatible with their parent point release. No new features, no breaking changes. If your application depends on a specific point release, stable updates are safe to apply. Security fixes go to the stable branch immediately, with a new point release tagged shortly after.

Far too many to list here. A small sample: - https://github.com/mholt/caddy Caddy is an HTTP/2 webserver written in Go that integrates with ACME and serves websites of TLS by default. It powers https://paragonie.com and manages our HTTPS certificates automatically. - https://github.com/twigphp/Twig Twig is one of the sane templating languages for PHP projects that I use extensively. - https://github.com/composer/composer Composer revolutionized PHP development. A lot of the "PHP sucks" arguments focus on things that haven't been true about the language since 5.4 (or earlier), but one thing that truly did suck was dependency management (before composer came around). Dependency management also sucks in other languages (and still sucks in those). I suspect that's why few used that as a criticism of PHP. - https://github.com/jedisct1/libsodiu

Well this particular project this comment thread is about does not actually implement any cryptographic operations, those are all done by libsodium[1] a project written in C. Imagine now it is possible to construct an argument to those libsodium functions that satisfies the constraints of the Rust wrappers, but still manages to crash libsodium and execute some part of the argument, which is not unheard of since libsodium is written in C and it operates on blobs of data. Now the only mistake the implementor of thrussh has to make is to allow for that input to be passed into the rust libsodium wrapper through the protocol implementation.

Also: Don't implement chacha20-poly1305 or AES-GCM yourself, unless you're a crypto expert. You'll more than likely make a mistake. Libsodium offers both (but AES-256-GCM is only available if you have hardware support for constant-time implementations). crypto_aead_chacha20poly1305_encrypt() crypto_aead_chacha20poly1305_decrypt() crypto_aead_aes256gcm_encrypt() crypto_aead_aes256gcm_decrypt() https://github.com/jedisct1/libsodium
