Trait Implementations

impl<Aes> AeadCore for AesGcmSiv<Aes> where
    Aes: NewBlockCipher + BlockCipher<BlockSize = U16> + BlockEncrypt,
    Aes::ParBlocks: ArrayLength<Block<Aes>>, 

type NonceSize = U12

The length of a nonce.

type TagSize = U16

The maximum length of the nonce.

type CiphertextOverhead = U0

The upper bound amount of additional space required to support a ciphertext vs. a plaintext.

impl<Aes> AeadInPlace for AesGcmSiv<Aes> where
    Aes: NewBlockCipher + BlockCipher<BlockSize = U16> + BlockEncrypt,
    Aes::ParBlocks: ArrayLength<Block<Aes>>, 

fn encrypt_in_place_detached(
    &self,
    nonce: &Nonce,
    associated_data: &[u8],
    buffer: &mut [u8]
) -> Result<Tag, Error>

Encrypt the data in-place, returning the authentication tag

fn decrypt_in_place_detached(
    &self,
    nonce: &Nonce,
    associated_data: &[u8],
    buffer: &mut [u8],
    tag: &Tag
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext (i.e. ciphertext is modified/unauthentic)

fn encrypt_in_place(
    &self,
    nonce: &GenericArray<u8, Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Encrypt the given buffer containing a plaintext message in-place.

fn decrypt_in_place(
    &self,
    nonce: &GenericArray<u8, Self::NonceSize>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext.

impl<Aes: Clone> Clone for AesGcmSiv<Aes> where
    Aes: BlockCipher<BlockSize = U16> + BlockEncrypt,
    Aes::ParBlocks: ArrayLength<Block<Aes>>, 

fn clone(&self) -> AesGcmSiv<Aes>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Aes> From<Aes> for AesGcmSiv<Aes> where
    Aes: BlockCipher<BlockSize = U16> + BlockEncrypt,
    Aes::ParBlocks: ArrayLength<Block<Aes>>, 

fn from(key_generating_key: Aes) -> Self

Performs the conversion.

impl<Aes> NewAead for AesGcmSiv<Aes> where
    Aes: NewBlockCipher + BlockCipher<BlockSize = U16> + BlockEncrypt,
    Aes::ParBlocks: ArrayLength<Block<Aes>>, 

type KeySize = Aes::KeySize

The size of the key array required by this algorithm.

fn new(key_bytes: &Key<Aes::KeySize>) -> Self

Create a new AEAD instance with the given key.

fn new_from_slice(key: &[u8]) -> Result<Self, Error>

Create new AEAD instance from key given as a byte slice..

fn generate_key(
    rng: impl CryptoRng + RngCore
) -> GenericArray<u8, Self::KeySize>

Generate a random key for this AEAD using the provided CryptoRng.
