Struct tink_aead::subtle::AesCtr

[+] Show declaration

pub struct AesCtr {
    pub iv_size: usize,
    // some fields omitted
}

[−] Expand description

AesCtr is an implementation of AEAD interface.

Fields

iv_size: usize

Implementations

impl AesCtr[−]

pub fn new(key: &[u8], iv_size: usize) -> Result<AesCtr, TinkError>[−]

Return an AesCtr instance. The key argument should be the AES key, either 16 or 32 bytes to select AES-128 or AES-256. iv_size specifies the size of the IV in bytes.

pub fn key_len(&self) -> usize[−]

Return the length of the key.

Trait Implementations

impl Clone for AesCtr[+]

[+] Show hidden undocumented items

fn clone(&self) -> AesCtr[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl IndCpaCipher for AesCtr[+]

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

Encrypt plaintext using AES in CTR mode. The resulting ciphertext consists of two parts: (1) the IV used for encryption and (2) the actual ciphertext.

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

Decrypt ciphertext.
