Trait Implementations

impl AeadCore for Aes256Gcm

type NonceSize = UInt<UInt<UInt<UInt<UTerm, B1>, B1>, B0>, B0>

The length of a nonce.

type TagSize = UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>

The maximum length of the nonce.

type CiphertextOverhead = UTerm

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

impl AeadInPlace for Aes256Gcm

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

Encrypt the data in-place, returning the authentication tag

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.

fn decrypt_in_place_detached( &self, _nonce: &GenericArray<u8, Self::NonceSize>, _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.

impl KeyInit for Aes256Gcm

fn new(key: &GenericArray<u8, Self::KeySize>) -> Self

Create new value from fixed size key.

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

Create new value from variable size key.

impl KeySizeUser for Aes256Gcm

type KeySize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>

Key size in bytes.

fn key_size() -> usize

Return key size in bytes.
