Struct AesDma

pub struct AesDma<'d> {
    pub aes: Aes<'d>,
    /* private fields */
}

Available on crate feature unstable only.

A DMA capable AES instance.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Fields

aes: Aes<'d>

The underlying Aes driver

Implementations

impl<'d> AesDma<'d>

pub fn write_key<K>(&mut self, key: K)

where K: Into<Key>,

Writes the encryption key to the AES hardware, checking that its length matches expected constraints.

pub fn write_block(&mut self, block: &[u8])

Writes a block of data to the AES hardware, ensuring the block’s length is properly aligned.

pub fn process<K, RXBUF, TXBUF>( self, number_of_blocks: usize, output: RXBUF, input: TXBUF, mode: Mode, cipher_mode: CipherMode, key: K, ) -> Result<AesTransfer<'d, RXBUF, TXBUF>, (DmaError, Self, RXBUF, TXBUF)>

where K: Into<Key>, TXBUF: DmaTxBuffer, RXBUF: DmaRxBuffer,

Perform a DMA transfer.

This will return a AesTransfer. The maximum amount of data to be sent/received is 32736 bytes.
