Class CertHash

java.lang.Object
org.bouncycastle.asn1.ASN1Object
org.bouncycastle.asn1.isismtt.ocsp.CertHash
All Implemented Interfaces:
ASN1Encodable, Encodable

public class CertHash extends ASN1Object
ISIS-MTT PROFILE: The responder may include this extension in a response to send the hash of the requested certificate to the responder. This hash is cryptographically bound to the certificate and serves as evidence that the certificate is known to the responder (i.e. it has been issued and is present in the directory). Hence, this extension is a means to provide a positive statement of availability as described in T8.[8]. As explained in T13.[1], clients may rely on this information to be able to validate signatures after the expiry of the corresponding certificate. Hence, clients MUST support this extension. If a positive statement of availability is to be delivered, this extension syntax and OID MUST be used.
