Struct MAC

Source 
pub struct MAC { /* private fields */ }
Expand description

Ethereum MAC state.

The ethereum MAC is a cursed MAC construction.

The ethereum MAC is a nonstandard MAC construction that uses AES-256 (without a mode, as a block cipher) and Keccak-256. However, it only ever encrypts messages that are 128 bits long, and is not defined as a general MAC.

Implementations§

Source§

impl MAC

Source

pub fn new(secret: B256) -> Self

Initialize the MAC with the given secret

Source

pub fn update(&mut self, data: &[u8])

Update the internal keccak256 hasher with the given data

Source

pub fn update_header(&mut self, data: &HeaderBytes)

Accumulate the given HeaderBytes into the MAC’s internal state.

Source

pub fn update_body(&mut self, data: &[u8])

Accumulate the given message body into the MAC’s internal state.

Source

pub fn digest(&self) -> B128

Produce a digest by finalizing the internal keccak256 hasher and returning the first 128 bits.
