Struct coconut_sig::signature::Signature

pub struct Signature {
    pub sigma_1: SignatureGroup,
    pub sigma_2: SignatureGroup,
}

Result of the unblinding of the blind signature. Is in the form of PS signature.

Fields

sigma_1: SignatureGroup

sigma_2: SignatureGroup

Methods

impl Signature

pub fn aggregate(threshold: usize, sigs: Vec<(usize, Signature)>) -> Signature

Create an aggregated signature from signatures from various signers. "AggCred" from paper.

pub fn verify(
    &self,
    messages: Vec<FieldElement>,
    vk: &Verkey,
    params: &Params
) -> bool

Verify a signature. Can verify unblinded sig received from a signer and the aggregate sig as well.
