lib64security

lib64security is an open-source cryptographic and security library designed for 64-bit platforms. It provides a suite of cryptographic primitives, secure memory handling, and key management intended to deliver high performance in server, desktop, and embedded environments.

The project targets cross-platform compatibility on Linux, BSD, Windows 64-bit, and macOS. Implemented primarily in C, lib64security emphasizes a clean application binary interface, minimal dependencies, and a well-documented API suitable for embedding in other applications and frameworks.

Key features include:

- Symmetric algorithms such as AES and ChaCha20-Poly1305

- Public-key cryptography including RSA, ECDSA, and Ed25519

- Hash and MAC functions like SHA-2, SHA-3, BLAKE2, and HMAC

- Key derivation and randomness machinery (HKDF, Argon2, scrypt, secure RNG)

- Protocol and certificate utilities, including X.509 helpers

- Crypto contexts, streaming interfaces, constant-time implementations, and memory sanitization

lib64security uses a modular design with a core primitives module and optional higher-level components. It provides C APIs and community-maintained bindings for languages such as Python, Rust, and Go, facilitating integration with a variety of projects and frameworks.

Licensing and governance: lib64security is released under a permissive license (BSD-3-Clause). The project maintains contribution guidelines, a test suite, fuzzing infrastructure, and periodic security reviews to uphold quality and safety.
