Expand description

A pure-rust implementation of various cryptographic algorithms, which no dependencies and no foreign code (specially C or assembly).

Our goals is to support rust cryptography in various constrained environment like embedded devices and web assembly

This is a fork of Rust-Crypto by DaGenix, which we owe a debt of gratitude for starting some good quality pure rust implementations of various cryptographic algorithms.

Notable Differences with the original sources:

  • Maintained
  • Extended ED25519 support for extended secret key (64 bytes) support
  • Proper implementation of ChaChaPoly1305
  • Many cryptographic algorithms removed: AES, Blowfish, Fortuna, RC4, RIPEMD160, Whirlpool, MD5, SHA1.

As with everything cryptographic implementations, please make sure it suits your security requirements, and review and audit before using.
