Remarks
Abstract class for an X.509 Certificate Revocation List (CRL). A CRL is a time-stamped list identifying revoked certificates. It is signed by a Certificate Authority (CA) and made freely available in a public repository.
Each revoked certificate is identified in a CRL by its certificate serial number. When a certificate-using system uses a certificate (e.g., for verifying a remote user's digital signature), that system not only checks the certificate signature and validity but also acquires a suitably- recent CRL and checks that the certificate serial number is not on that CRL. The meaning of "suitably-recent" may vary with local policy, but it usually means the most recently-issued CRL. A CA issues a new CRL on a regular periodic basis (e.g., hourly, daily, or weekly). Entries are added to CRLs as revocations occur, and an entry may be removed when the certificate expiration date is reached.
The X.509 v2 CRL format is described below in ASN.1:
CertificateList ::= SEQUENCE {
tbsCertList TBSCertList,
signatureAlgorithm AlgorithmIdentifier,
signature BIT STRING }
More information can be found in RFC 3280: Internet X.509 Public Key Infrastructure Certificate and CRL Profile.
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
}
CRLs are instantiated using a certificate factory. The following is an example of how to instantiate an X.509 CRL:
{@code
try (InputStream inStream = new FileInputStream("fileName-of-crl")) {
CertificateFactory cf = CertificateFactory.getInstance("X.509");
X509CRL crl = (X509CRL)cf.generateCRL(inStream);
}
}
