Trait Implementations

impl Aead for Aes256Gcm

fn encrypt(
    key: &Key<Self>,
    nonce: &Nonce<Self>,
    associated_data: &[u8],
    plaintext: &[u8],
    ciphertext: &mut [u8],
    tag: &mut Tag<Self>
) -> Result<()>

Warning: type conversions on the tag type can be tricky. instead of &mut tag.try_into().unwrap() use (&mut tag).try_into().unwrap()

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

The size of the key required by this algorithm.

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

The size of the nonce required by this algorithm.

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

The size of the tag produced by this algorithm.

const NAME: &'static str = "AES-256-GCM"

A human-friendly identifier of this algorithm.

    nonce: &[u8],
    associated_data: &[u8],
    plaintext: &[u8],
    ciphertext: &mut [u8],
    tag: &mut [u8]
) -> Result<()>

    plaintext: &mut [u8],
    ciphertext: &[u8],
    tag: &[u8]
) -> Result<usize>

Decrypt the given ciphertext using key and tag.

fn random_nonce() -> Result<Nonce<Self>>
