Struct ChaCha20Poly1305Cipher 

pub struct ChaCha20Poly1305Cipher(/* private fields */);

A stateless ChaCha20Poly1305 cipher. Callers supply the full 12-byte IETF nonce on every call.

Nonce management is the caller’s responsibility — typically handled by StrobeNkTransport.

Implementations

impl ChaCha20Poly1305Cipher

pub fn new(key: &[u8; 32]) -> Self

pub fn encrypt( &self, nonce: ChaCha20Nonce, aad: &[u8], plaintext: &[u8], ciphertext: &mut [u8], ) -> Result<(), Error>

Encrypts plaintext into ciphertext (ciphertext || tag). ciphertext.len() must equal plaintext.len() + TAG_LEN.

pub fn decrypt( &self, nonce: ChaCha20Nonce, aad: &[u8], ciphertext: &[u8], plaintext: &mut [u8], ) -> Result<(), Error>

Decrypts ciphertext (ciphertext || tag) into plaintext. ciphertext.len() must be at least TAG_LEN; plaintext.len() must equal ciphertext.len() - TAG_LEN.
