public class X509CRLImpl extends java.security.cert.X509CRL
An implmentation for X509 CRL (Certificate Revocation List).
The X.509 v2 CRL format is described below in ASN.1:
CertificateList ::= SEQUENCE { tbsCertList TBSCertList, signatureAlgorithm AlgorithmIdentifier, signature BIT STRING }
A good description and profiling is provided in the IETF PKIX WG draft, Part I: X.509 Certificate and CRL Profile, <draft-ietf-pkix-ipki-part1-06.txt>.
The ASN.1 definition of
tbsCertList
is:TBSCertList ::= SEQUENCE { version Version OPTIONAL, -- if present, must be v2 signature AlgorithmIdentifier, issuer Name, thisUpdate ChoiceOfTime, nextUpdate ChoiceOfTime OPTIONAL, revokedCertificates SEQUENCE OF SEQUENCE { userCertificate CertificateSerialNumber, revocationDate ChoiceOfTime, crlEntryExtensions Extensions OPTIONAL -- if present, must be v2 } OPTIONAL, crlExtensions [0] EXPLICIT Extensions OPTIONAL -- if present, must be v2 }
