Struct tink_aead::subtle::AesGcm

pub struct AesGcm { /* fields omitted */ }

AesGcm is an implementation of the tink_core::Aead trait.

Implementations

impl AesGcm

pub fn new(key: &[u8]) -> Result<AesGcm, TinkError>

Return an AesGcm instance. The key argument should be the AES key, either 16 or 32 bytes to select AES-128 or AES-256.

Trait Implementations

impl Aead for AesGcm

fn encrypt(&self, pt: &[u8], aad: &[u8]) -> Result<Vec<u8>, TinkError>

Encrypt pt with aad as additional authenticated data. The resulting ciphertext consists of two parts: (1) the IV used for encryption and (2) the actual ciphertext.

Note: AES-GCM implementation of crypto library always returns ciphertext with 128-bit tag.

fn decrypt(&self, ct: &[u8], aad: &[u8]) -> Result<Vec<u8>, TinkError>

Decrypt ct with aad as the additional authenticated data.

impl Clone for AesGcm

fn clone(&self) -> AesGcm

Returns a copy of the value.

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

Performs copy-assignment from source.
