Struct Aes 

pub struct Aes<'d, T: Instance, M: Mode> { /* private fields */ }

AES driver.

Implementations

impl<'d, T: Instance> Aes<'d, T, Blocking>

pub fn new_blocking( peripheral: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Instantiates, resets, and enables the AES peripheral.

impl<'d, T: Instance> Aes<'d, T, Async>

pub fn new( peripheral: Peri<'d, T>, dma_in: Peri<'d, impl DmaIn<T>>, dma_out: Peri<'d, impl DmaOut<T>>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Instantiates, resets, and enables the AES peripheral with DMA support.

impl<'d, T: Instance, M: Mode> Aes<'d, T, M>

pub fn start<'c, C>(&mut self, cipher: &'c C, dir: Direction) -> Context<'c, C>

where C: Cipher<'c> + CipherSized + IVSized,

Starts a new cipher operation and returns the context.

pub fn aad_blocking<'c, C>( &mut self, ctx: &mut Context<'c, C>, aad: &[u8], last: bool, ) -> Result<(), Error>

where C: Cipher<'c> + CipherAuthenticated<16>,

Process authenticated additional data (AAD) for GCM/CCM modes. Must be called after start and before payload_blocking. Set last to true for the final AAD block.

pub fn payload_blocking<'c, C>( &mut self, ctx: &mut Context<'c, C>, input: &[u8], output: &mut [u8], last: bool, ) -> Result<(), Error>

where C: Cipher<'c>,

Process payload data in blocking mode.

Set last to true for the final block. Intermediate chunks (last=false) must be block-aligned (16 bytes). Only the final chunk can be a partial block.

pub fn finish_blocking<'c, C>( &mut self, ctx: Context<'c, C>, ) -> Result<Option<[u8; 16]>, Error>

where C: Cipher<'c>,

Finishes the cipher operation and returns the authentication tag (for GCM/CCM).
