ChaCha20Poly1305

✓ use chacha20poly1305::ChaCha20Poly1305;

Encrypts a plaintext using ChaCha20Poly1305 with a random key and a nonce.

use chacha20poly1305::ChaCha20Poly1305; use chacha20poly1305::aead::{Aead, KeyInit, Nonce}; let key = ChaCha20Poly1305::generate_key(&mut rand::thread_rng()); let cipher = ChaCha20Poly1305::new(&key); let nonce = Nonce::from_slice(b"unique nonce"); let ciphertext = cipher.encrypt(nonce, b"plaintext").expect("encryption failure"); println!("Encrypted: {:?}", ciphertext);

Debug

Known issues

gotchaRequires the `rand_core` feature for key generation; otherwise, you must provide a key manually.

fix

Add `rand_core` as a dependency or use `ChaCha20Poly1305::new_from_slice` with a pre-generated key.

affects: >=0.10.0
