Struct bbs::BlindSignatureContext

pub struct BlindSignatureContext {
    pub commitment: Commitment,
    pub challenge_hash: ProofChallenge,
    pub proof_of_hidden_messages: ProofG1,
}

Contains the data used for computing a blind signature and verifying proof of hidden messages from a prover

Fields

commitment: Commitment

The blinded signature commitment

challenge_hash: ProofChallenge

The challenge hash for the Fiat-Shamir heuristic

proof_of_hidden_messages: ProofG1

The proof for the hidden messages

Implementations

impl BlindSignatureContext

pub fn verify(
    &self,
    revealed_messages: &BTreeSet<usize>,
    verkey: &PublicKey,
    nonce: &ProofNonce
) -> Result<bool, BBSError>

Assumes the proof of hidden messages If other proofs were included, those will need to be verified another way
