Collection of block ciphers written in pure Rust.
Crates in this repository implement ONLY raw block cipher functionality defined by traits in the cipher
crate.
In practice block ciphers are rarely used in isolation.
Instead, they usually play role of a building block for higher level constructions.
In RustCrypto such constructions are implemented generically over block ciphers in separate repositories:
- AEADs: GCM, SIV, CCM, MGM, etc.
- MACs: CMAC, PMAC.
- Block modes: CTR, CBC, CFB, etc.
- Key wrapping: AES-KW.
Most users should use constructions defined in these repositories without directly relying on raw block cipher functionality.
Currently only the aes
crate provides constant-time implementation and has received a third-party security audit.
Other crates in this repository are not implemented in a constant-time manner and have not yet received any formal cryptographic and security reviews.
It's generally recommended not to use other cipher implementations in this repository besides the aes
crate.
