Record Class CredentialConfirmationProofChallenge

java.lang.Object

java.lang.Record

zeroecho.pki.api.confirmation.CredentialConfirmationProofChallenge

Record Components:

proofCas - exact pending lifecycle and issued challenge correlation coordinates

proofSuiteBinding - exact suite binding used to construct the presentation

expiresAt - authoritative whole-second challenge expiry

maximumResponseBytes - inclusive response bound from 1 through 16384 bytes

presentation - non-empty suite-defined presentation, at most 2048 bytes

public record CredentialConfirmationProofChallenge(CredentialConfirmationProofCas proofCas, ConfirmationProofSuiteBinding proofSuiteBinding, Instant expiresAt, int maximumResponseBytes, byte[] presentation)
extends Record

Immutable safe presentation of one issued credential-confirmation proof challenge.

The challenge-record commitment inside proofCas is a non-secret correlation and compare-and-set coordinate. Possession of it grants no authorization, disclosure access, or evidence of key possession.
