Trait Implementations

impl Debug for ChaCha20Poly1305

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Dem<{ Self::KEY_LENGTH }, { Self::NONCE_LENGTH }, { Self::MAC_LENGTH }, ChaChaPoly1305<StreamCipherCoreWrapper<ChaChaCore<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B1>, B0>>>>> for ChaCha20Poly1305

type Nonce = Nonce<{ Self::NONCE_LENGTH }>

fn encrypt( &self, nonce: &Self::Nonce, plaintext: &[u8], aad: Option<&[u8]>, ) -> Result<Vec<u8>, CryptoCoreError>

Encrypts a plaintext using the given symmetric key.

fn decrypt( &self, nonce: &Self::Nonce, ciphertext: &[u8], aad: Option<&[u8]>, ) -> Result<Vec<u8>, CryptoCoreError>

Decrypts a ciphertext using the given symmetric key.

impl DemInPlace<{ Self::KEY_LENGTH }, { Self::NONCE_LENGTH }, { Self::MAC_LENGTH }, ChaChaPoly1305<StreamCipherCoreWrapper<ChaChaCore<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B1>, B0>>>>> for ChaCha20Poly1305

type Nonce = Nonce<{ Self::NONCE_LENGTH }>

fn encrypt_in_place_detached( &self, nonce: &Self::Nonce, plaintext: &mut [u8], aad: Option<&[u8]>, ) -> Result<Vec<u8>, CryptoCoreError>

Encrypts a message in place using a secret key and a public nonce in detached mode: the tag authenticating both the confidential message and non-confidential data, are returned separately

fn decrypt_in_place_detached( &self, nonce: &Self::Nonce, bytes: &mut [u8], tag: &[u8], aad: Option<&[u8]>, ) -> Result<(), CryptoCoreError>

Decrypts a message in pace in detached mode. The bytes should not contain the authentication tag.

type Nonce = Nonce<{ Self::NONCE_LENGTH }>

fn into_aead_stream_backend(self) -> ChaCha20Poly1305Lib

Returns the RustCrypto Aead in place backend algorithm with stream capabilities

fn into_stream_encryptor_be32( self, nonce: &Self::Nonce, ) -> EncryptorBE32<RustCryptoBackend>

fn into_stream_decryptor_be32( self, nonce: &Self::Nonce, ) -> DecryptorBE32<RustCryptoBackend>

fn into_stream_encryptor_le31( self, nonce: &Self::Nonce, ) -> EncryptorLE31<RustCryptoBackend>

fn into_stream_decryptor_le31( self, nonce: &Self::Nonce, ) -> DecryptorLE31<RustCryptoBackend>

impl Deref for ChaCha20Poly1305

type Target = ChaChaPoly1305<StreamCipherCoreWrapper<ChaChaCore<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B1>, B0>>>>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Instantiable<{ Self::KEY_LENGTH }> for ChaCha20Poly1305

type Secret = SymmetricKey<{ Self::KEY_LENGTH }>

fn new(symmetric_key: &Self::Secret) -> Self

Instantiate the DEM
