Fields

regs: *const AESECB_REGS

client: Cell<Option<&'a Client<'a>>>

input: TakeCell<'a, [u8]>

Input either plaintext or ciphertext to be encrypted or decrypted.

output: TakeCell<'a, [u8]>

keystream: Cell<[u8; 128]>

Keystream to be XOR'ed with the input.

current_idx: Cell<usize>

start_idx: Cell<usize>

end_idx: Cell<usize>

Methods

impl<'a> AesECB<'a>

const fn new() -> AesECB<'a>

fn init_dma(&self)

fn update_ctr(&self)

fn crypt(&self)

pub fn handle_interrupt(&self)

fn enable_interrupts(&self)

fn disable_interrupts(&self)

Trait Implementations

impl<'a> AES128<'a> for AesECB<'a>

fn enable(&self)

Enable the AES hardware. Must be called before any other methods

fn disable(&self)

Disable the AES hardware

fn set_client(&'a self, client: &'a Client<'a>)

Set the client instance which will receive crypt_done() callbacks

fn set_key(&self, key: &[u8]) -> ReturnCode

Set the encryption key. Returns EINVAL if length is not AES128_KEY_SIZE

fn set_iv(&self, iv: &[u8]) -> ReturnCode

Set the IV (or initial counter). Returns EINVAL if length is not AES128_BLOCK_SIZE

fn start_message(&self)

Begin a new message (with the configured IV) when crypt() is next called. Multiple calls to crypt() may be made between calls to start_message(), allowing the encryption context to extend over non-contiguous extents of data.

fn crypt(
    &'a self,
    source: Option<&'a mut [u8]>,
    dest: &'a mut [u8],
    start_index: usize,
    stop_index: usize
) -> Option<(ReturnCode, Option<&'a mut [u8]>, &'a mut [u8])>

Request an encryption/decryption

impl<'a> AES128Ctr for AesECB<'a>

fn set_mode_aes128ctr(&self, _encrypting: bool)

Call before AES128::crypt() to perform AES128Ctr
