impl TranscriptProtocol for Transcript

fn new(label: &'static [u8]) -> Self

Create a new transcript with the given domain-separation label.

fn append_message(&mut self, label: &'static [u8], message: &[u8])

Absorb an arbitrary byte string under a label.

fn append_u64(&mut self, label: &'static [u8], value: u64)

Absorb a u64 value under a label.

fn challenge_bytes(&mut self, label: &'static [u8], dest: &mut [u8])

Fill dest with challenge bytes derived from the transcript state.

fn append_point<C>(&mut self, label: &'static [u8], point: &C::ProjectivePoint)

where C: CurveArithmetic, C::FieldBytesSize: ModulusSize, C::ProjectivePoint: ToEncodedPoint<C>,

Absorb an elliptic-curve point in compressed form.
