A (mostly) pure-Rust implementation of various common cryptographic algorithms.

Rust-Crypto seeks to create practical, auditable, pure-Rust implementations of common cryptographic algorithms with a minimum amount of assembly code where appropriate. The x86-64, x86, and ARM architectures are supported, although the x86-64 architecture receives the most testing.

Rust-Crypto targets the current, stable build of Rust. If you are having issues while using an older version, please try upgrading to the latest stable.

Rust-Crypto has not been thoroughly audited for correctness, so any use where security is important is not recommended at this time.

To use Rust-Crypto, add the following to your Cargo.toml:

[dependencies]
rust-crypto = "^0.2"

and the following to your crate root:

extern crate crypto;

Contributions are extremely welcome. The most significant needs are help adding documentation, implementing new algorithms, and general cleanup and improvement of the code. By submitting a pull request you are agreeing to make you work available under the license terms of the Rust-Crypto project.

Rust-Crypto is dual licensed under the MIT and Apache 2.0 licenses, the same licenses as the Rust compiler.

Rust-Crypto already supports a significant number of algorithms and with your help it will support even more in the future. Currently supported algorithms include:

• AES
• Bcrypt
• BLAKE2b
• BLAKE2s
• Blowfish
• ChaCha20
• Curve25519
• ECB, CBC, and CTR block cipher modes
• Ed25519
• Fortuna
• Ghash
• HC128
• HMAC
• MD5
• PBKDF2
• PKCS padding for CBC block cipher mode
• Poly1305
• RC4
• RIPEMD-160
• Salsa20 and XSalsa20
• Scrypt
• Sha1
• Sha2 (All fixed output size variants)
• Sha3
• Sosemanuk
• Whirlpool
