simple extension methods which make working with cryptography easier

Batteries-included Go cryptography library: AES-256-GCM & ChaCha20-Poly1305 authenticated encryption, argon2id/bcrypt password hashing, HMAC & Ed25519 signing, HKDF, key rotation, KMS envelope encryption, and secure random — safe defaults, stdlib-only, byte-for-byte interop with the TypeScript crypt-ts.

Python ASN.1 library with a focus on performance and a pythonic API

PHP Privacy - The OpenPGP library in PHP language

Deterministic security-engineering range for authoritative simulation, protocol hardening, evidence integrity, forensic replay, analytics, and reproducible verification.

Config, code, and encryption in one `.mdix` file. Monorepo for the DixScript compiler: dixscript (Rust core, on crates.io), mdix-cli, mdix-lsp, and FFI bindings for C#, Go, Python, WASM, and C.

SipHash (2-4, 1-3 + 128 bit variant) implementations for Rust

Pure rust implementation of web-push and related standards

MagicCrypt is a Java/PHP/NodeJS/Rust library to encrypt/decrypt strings, files, or data, using Data Encryption Standard(DES) or Advanced Encryption Standard(AES) algorithms. It supports CBC block cipher mode, PKCS7 padding and 64, 128, 192 or 256-bits key length.

A dependency-free, no_std Rust crate for secure in-memory secret handling, constant-time checks, and automated clear-on-drop zeroization.

Blake3.NET provides two fast, SIMD-accelerated implementations of the BLAKE3 cryptographic hash function: the fully managed Blake3 package and the native Blake3.Native package, which wraps the official Rust implementation.

Ed25519 high-performance public-key signature system as a RubyGem (MRI C extension and JRuby Java extension)

Majik Key is a next-generation seed phrase account library for creating and managing mnemonic-based identities. It provides a post-quantum ready, high-security bridge between BIP39 mnemonics and the Majikah ecosystem.

Majik Signature is a hybrid post-quantum content signing and verification library for the Majikah ecosystem. Built on top of Majik Key, it provides tamper-proof, forgery-resistant digital signatures for any content format — using a dual-algorithm architecture that combines classical Ed25519 with post-quantum ML-DSA-87 (FIPS-204).

This crate is a repository of MLS / RFC9420-related data structures.
