Struct Verifier

pub struct Verifier;

This struct represents an Verifier of signatures. Provided are methods for generating a context to ask for revealed messages and the prover keep all others hidden.

Implementations

impl Verifier

pub fn new_proof_request( revealed_message_indices: &[usize], verkey: &PublicKey, ) -> Result<ProofRequest, BBSError>

Create a nonce used for the zero-knowledge proof context verkey: issuer’s public key

pub fn verify_signature_pok( proof_request: &ProofRequest, signature_proof: &SignatureProof, nonce: &ProofNonce, ) -> Result<Vec<SignatureMessage>, BBSError>

Check a signature proof of knowledge and selective disclosure proof

pub fn generate_proof_nonce() -> ProofNonce

Create a nonce used for the proof request context

pub fn create_challenge_hash( proofs: &[SignatureProof], proof_requests: &[ProofRequest], nonce: &ProofNonce, claims: Option<&[&[u8]]>, ) -> Result<ProofChallenge, BBSError>

create the challenge hash for a set of proofs

Arguments

• proofs - a slice of SignatureProof objects
• proof_requests - a corresponding slice of ProofRequest objects
• nonce - a SignatureNonce
• claims - an optional slice of bytes the prover wishes to include in the challenge
