tachyon

tachyon is a high-performance algorithm library written in Rust, providing SIMD-accelerated implementations for both x86 (AVX/SSE) and ARM (NEON) architectures, to outperform even hand-tuned assembly in many cases.

• Optimized for both x86_64 (SSE, AVX) and aarch64 (NEON) platforms.
• Focused on performance — carefully tuned SIMD intrinsics for critical code paths.
• SIMD implementations often outperform well-known on ARM NEON.
• Designed for performance-critical applications like embedded systems, secure networking, and data processing.

Add to your Cargo.toml:

tachyon = { git = "https://github.com/SongXiaoXi/tachyon-rs" }

or use cargo:

cargo add tachyon --git https://github.com/SongXiaoXi/tachyon-rs

use tachyon::crypto::hash::md5;

let digest = md5::compute(b"hello world");

Tip:

• On older Apple devices (e.g., A7–A10), compiling with rust nightly and -Ztune-cpu=generic may produce more favorable NEON code generation.

This library is designed for performance benchmarking and experimentation.
It has not been formally audited for cryptographic soundness.
Do not use in production unless you fully understand the risks.

This project builds upon the work and ideas of several excellent Rust cryptography projects:

• crypto2: for its clean and pragmatic API design around cryptographic primitives, as well as software fallback implementations of several algorithms.
• RustCrypto AES: used as a software fallback for the AES fixslicing implementation.
