Struct microbit::hal::Ecb

pub struct Ecb { /* fields omitted */ }

A safe, blocking wrapper around the AES-ECB peripheral.

It’s really just blockwise AES and not an ECB stream cipher. Blocks can be encrypted by calling crypt_block.

Implementations

impl Ecb

pub fn init(regs: ECB) -> Ecb

Takes ownership of the ECB peripheral, returning a safe wrapper.

pub fn into_inner(self) -> ECB

Destroys self, giving the ECB peripheral back.

pub fn encrypt_block(
    &mut self,
    block: [u8; 16],
    key: [u8; 16]
) -> Result<[u8; 16], EncryptionError>

Blocking encryption.

Encrypts a block with key.

Errors

An error will be returned when the AES hardware raises an ERRORECB event. This can happen when an operation is started that shares the AES hardware resources with the AES ECB peripheral while an encryption operation is running.
