Struct Signature

Source 
pub struct Signature<C: Ciphersuite> { /* private fields */ }
Expand description

A Schnorr signature over some prime order group (or subgroup).

Implementations§

Source§

impl<C: Ciphersuite> Signature<C>

Auto-generated by derive_getters::Getters.

Source

pub fn R(&self) -> &Element<C>

The commitment R to the signature nonce.

Source

pub fn z(&self) -> &Scalar<C>

The response z to the challenge computed from the commitment R, the verifying key, and the message.

Source§

impl<C> Signature<C>
where C: Ciphersuite, C::Group: Group, <C::Group as Group>::Field: Field,

Source

pub fn deserialize(bytes: &[u8]) -> Result<Self, Error<C>>

Converts bytes as Ciphersuite::SignatureSerialization into a Signature<C>.

Source

pub fn serialize(&self) -> Result<Vec<u8>, Error<C>>

Converts this signature to its byte serialization.
