verify

open suspend override fun verify(atTime: Instant, documentTypeRepository: DocumentTypeRepository?, zkSystemRepository: ZkSystemRepository?): List<VerifiedPresentation>

Verifies the cryptographic validity of the presentment and the issuer trust chain. This includes verifying that the credential holder approved all transactions that apply to the presented credentials, even if no data was sent as a response for a given transaction.

verifyNonce

open suspend override fun verifyNonce(nonce: ByteString)

Verifies that the presentation was bound to the expected nonce.
