Struct PolyvalLite 

pub struct PolyvalLite(/* private fields */);

The same thing as Polyval, except it only processes one block at a time.

This saves space, but can be slower if the input is more than a couple blocks long.

Implementations

impl PolyvalLite

pub fn new(key: &[u8; 16]) -> Option<Self>

Creates a new hash instance.

It returns None if key is all zeroes.

pub fn new_unchecked(key: &[u8; 16]) -> Self

Creates a hash instance from a known non-zero key.

Warning

Only use this method if key is known to be non-zero. Using an all zero key fixes the output to zero, regardless of the input.

pub fn update_block(&mut self, block: &[u8; 16])

Writes a single block to the running hash.

pub fn update_blocks(&mut self, blocks: &[[u8; 16]])

Writes one or more blocks to the running hash.

pub fn update_padded(&mut self, blocks: &[u8])

Writes one or more blocks to the running hash.

If the length of blocks is non-zero, it’s padded to the lowest multiple of BLOCK_SIZE.

pub fn tag(self) -> Tag

Returns the current authentication tag.

pub fn verify(self, expected_tag: &Tag) -> Choice

Reports whether the current authentication tag matches expected_tag.

pub fn export(&self) -> PolyvalState

Available on crate feature experimental only.

Exports the current state.

pub fn reset(&mut self, state: &PolyvalState)

Available on crate feature experimental only.

Resets the hash to state.

pub fn current_tag(&self) -> Tag

Available on crate feature experimental only.

Returns the current authentication tag without consuming the hash.
