Implementations

impl<'c, const KEY_SIZE: usize> AesGmac<'c, KEY_SIZE>

pub fn new(key: &'c [u8; KEY_SIZE], iv: &'c [u8; 12]) -> Self

Trait Implementations

impl<'c, const KEY_SIZE: usize> Cipher<'c> for AesGmac<'c, KEY_SIZE>

const BLOCK_SIZE: usize = 16usize

Processing block size. Determined by the processor and the algorithm.

fn key(&self) -> &'c [u8]

Returns the symmetric key.

fn iv(&self) -> &[u8]

Returns the initialization vector.

fn set_algomode(&self, p: Cryp)

Sets the processor algorithm mode according to the associated cipher.

fn init_phase_blocking<T: Instance, DmaIn, DmaOut>( &self, p: Cryp, _cryp: &Cryp<'_, T, DmaIn, DmaOut>, )

Performs any cipher-specific initialization.

async fn init_phase<T: Instance, DmaIn, DmaOut>( &self, p: Cryp, _cryp: &mut Cryp<'_, T, DmaIn, DmaOut>, )

Performs any cipher-specific initialization.

fn pre_final(&self, p: Cryp, _dir: Direction, padding_len: usize) -> [u32; 4]

Called prior to processing the last data block for cipher-specific operations.

const REQUIRES_PADDING: bool = false

Indicates whether the cipher requires the application to provide padding. If true, no partial blocks will be accepted (a panic will occur).

fn prepare_key(&self, _p: Cryp)

Performs any key preparation within the processor, if necessary.

fn post_final_blocking<T: Instance, DmaIn, DmaOut>( &self, _p: Cryp, _cryp: &Cryp<'_, T, DmaIn, DmaOut>, _dir: Direction, _int_data: &mut [u8; 16], _temp1: [u32; 4], _padding_mask: [u8; 16], )

Called after processing the last data block for cipher-specific operations.

async fn post_final<T: Instance, DmaIn, DmaOut>( &self, _p: Cryp, _cryp: &mut Cryp<'_, T, DmaIn, DmaOut>, _dir: Direction, _int_data: &mut [u8; 16], _temp1: [u32; 4], _padding_mask: [u8; 16], )

where DmaIn: DmaIn<T>, DmaOut: DmaOut<T>,

Called after processing the last data block for cipher-specific operations.

fn get_header_block(&self) -> &[u8]

Returns the AAD header block as required by the cipher.
