chacha20

library0.10.0rscratesunverified

The ChaCha20 stream cipher (RFC 8439) implemented in pure Rust using traits from the RustCrypto `cipher` crate, with optional architecture-specific hardware acceleration (AVX2, SSE2). Additionally provides the ChaCha8, ChaCha12, XChaCha20, XChaCha12 and XChaCha8 stream ciphers, and also optional rand_core-compatible RNGs based on those ciphers.

ChaCha20

✓ use chacha20::ChaCha20;

Encrypts a 64-byte buffer using ChaCha20 with a zero key and nonce.

use chacha20::ChaCha20; use chacha20::cipher::{KeyIvInit, StreamCipher}; fn main() { let key = [0u8; 32]; let nonce = [0u8; 12]; let mut cipher = ChaCha20::new(&key.into(), &nonce.into()); let mut data = [0u8; 64]; cipher.apply_keystream(&mut data); println!("Encrypted: {:?}", data); }
