Struct Aes128Ctr 

pub struct Aes128Ctr(/* private fields */);

AES-128 in CTR mode.

Create a new cipher with new. xor_keystream to encrypt or decrypt (CTR mode is symmetric). You can move in the keystream with set_counter.

The counter is a full 128-bit big-endian block and is incremented as a whole (NIST SP 800-38A §5.1) after every block, so the keystream would only repeat after 2¹²⁸ blocks. Encrypting more than 2³² blocks under one key and counter is therefore not silently truncated at the 32-bit boundary.

Implementations

impl Aes128Ctr

pub fn new(key: &[u8; 16]) -> Self

Create a new AES-128-CTR stream cipher from a 16-byte key.

The initial counter is zeroed.

pub fn set_counter(&mut self, counter: &[u8; 16])

Set the 16-byte counter block.

For GCM this is nonce || 0x00000002 (J₀ + 1).

Trait Implementations

impl Drop for Aes128Ctr

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl StreamCipher for Aes128Ctr

fn xor_keystream(&mut self, in_out: &mut [u8])

impl Zeroize for Aes128Ctr

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
