pub struct ChaCha20Poly1305 { /* private fields */ }

RFC 8439 ChaCha20-Poly1305 AEAD.

Trait Implementations

impl Aead for ChaCha20Poly1305

const KEY_LEN: usize = 32

Key length in bytes.

const NONCE_LEN: usize = 12

Nonce length in bytes.

const TAG_LEN: usize = 16

Authentication tag length in bytes.

fn new(key: &[u8]) -> Result<Self>

Bind a key to a cipher instance.

fn seal_detached( &self, nonce: &[u8], aad: &[u8], in_out: &mut [u8], tag: &mut [u8], ) -> Result<()>

Encrypt in_out in place and write the tag to tag.

fn open_detached( &self, nonce: &[u8], aad: &[u8], in_out: &mut [u8], tag: &[u8], ) -> Result<()>

Verify tag and decrypt in_out in place.

impl Algorithm for ChaCha20Poly1305

const ID: &'static str = "chacha20-poly1305"

Stable ontology identifier for this algorithm.

const NAME: &'static str = "ChaCha20-Poly1305"

Human-facing display name (for example "SHA-256").

impl Drop for ChaCha20Poly1305

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl SelfTest for ChaCha20Poly1305

fn self_test() -> Result<()>

Run the algorithm’s known-answer test.
