Function validate_proof_shape 

Source 
pub fn validate_proof_shape(
    proof: &IdentityProof,
    challenge: &IdentityChallenge,
) -> Result<(), AuthProtocolError>
Expand description

Validate an IdentityProof against a challenge (Section 15.3): the echoed nonce must match, and the key shape must match the declared scheme. Signature verification itself belongs to the verifier, which knows the trusted key set.
