RustCrypto: block modes

Collection of block modes written in pure Rust generic over block ciphers.

⚠️ Security Warning: Hazmat!

Crates in this repository do not ensure ciphertexts are authentic (i.e. by using a MAC to verify ciphertext integrity), which can lead to serious vulnerabilities if used incorrectly! AEADs provide simple authenticated encryption, which is much less error-prone than manual integrity verification.
