Struct Aes

pub struct Aes<'a> { /* private fields */ }

Implementations

impl<'a> Aes<'a>

pub fn new() -> Aes<'a>

pub fn handle_interrupt(&self)

Handle an interrupt, which will indicate either that the AESA’s input buffer is ready for more data, or that it has completed a block of output for us to consume

Trait Implementations

impl<'a> AES128<'a> for Aes<'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 dyn Client<'a>)

Set the client instance which will receive crypt_done() callbacks

fn set_key(&self, key: &[u8]) -> Result<(), ErrorCode>

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

fn set_iv(&self, iv: &[u8]) -> Result<(), ErrorCode>

Set the IV (or initial counter). Returns INVAL 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( &self, source: Option<&'static mut [u8]>, dest: &'static mut [u8], start_index: usize, stop_index: usize, ) -> Option<(Result<(), ErrorCode>, Option<&'static mut [u8]>, &'static mut [u8])>

Request an encryption/decryption

impl AES128CBC for Aes<'_>

fn set_mode_aes128cbc(&self, encrypting: bool) -> Result<(), ErrorCode>

Call before AES128::crypt() to perform AES128CBC

impl AES128Ctr for Aes<'_>

fn set_mode_aes128ctr(&self, encrypting: bool) -> Result<(), ErrorCode>

Call before AES128::crypt() to perform AES128Ctr

impl AES128ECB for Aes<'_>

fn set_mode_aes128ecb(&self, encrypting: bool) -> Result<(), ErrorCode>

Call before AES128::crypt() to perform AES128ECB
