java.security.cert
Class X509CRLEntry

java.lang.Object
  java.security.cert.X509CRLEntry

All Implemented Interfaces:: X509Extension

public abstract class X509CRLEntry
extends Object
implements X509Extension
extends Object
implements X509Extension

Abstract class for a revoked certificate in a CRL (Certificate Revocation List). The ASN.1 definition for revokedCertificates is:

revokedCertificates SEQUENCE OF SEQUENCE { userCertificate CertificateSerialNumber, revocationDate ChoiceOfTime, crlEntryExtensions Extensions OPTIONAL -- if present, must be v2 } OPTIONAL

CertificateSerialNumber ::= INTEGER

Extensions ::= SEQUENCE SIZE (1..MAX) OF Extension

Extension ::= SEQUENCE { extnId OBJECT IDENTIFIER, critical BOOLEAN DEFAULT FALSE, extnValue OCTET STRING -- contains a DER encoding of a value -- of the type registered for use with -- the extnId object identifier value }

See Also:: X509CRL, X509Extension

Constructor Detail

X509CRLEntry

public X509CRLEntry()

Method Detail

equals

public boolean equals(Object other)

Compares this CRL entry for equality with the given object. If the other object is an instanceof X509CRLEntry, then its encoded form (the inner SEQUENCE) is retrieved and compared with the encoded form of this CRL entry.

Overrides:: equals in class Object

Parameters:: other - the object to test for equality with this CRL entry.
Returns:: true iff the encoded forms of the two CRL entries match, false otherwise.
See Also:: Object.hashCode(), Hashtable

hashCode

public int hashCode()

Returns a hashcode value for this CRL entry from its encoded form.

Overrides:: hashCode in class Object

Returns:: the hashcode value.
See Also:: Object.equals(java.lang.Object), Hashtable

getEncoded

public abstract byte[] getEncoded()
                           throws CRLException

Returns the ASN.1 DER-encoded form of this CRL Entry, that is the inner SEQUENCE.

Returns:: the encoded form of this certificate
Throws:: CRLException - if an encoding error occurs.

getSerialNumber

public abstract BigInteger getSerialNumber()

Gets the serial number from this X509CRLEntry, the userCertificate.

Returns:: the serial number.

getCertificateIssuer

public X500Principal getCertificateIssuer()

Get the issuer of the X509Certificate described by this entry. If the certificate issuer is also the CRL issuer, this method returns null.

This method is used with indirect CRLs. The default implementation always returns null. Subclasses that wish to support indirect CRLs should override it.

Returns:: the issuer of the X509Certificate described by this entry or null if it is issued by the CRL issuer.
Since:: 1.5

getRevocationDate

public abstract Date getRevocationDate()

Gets the revocation date from this X509CRLEntry, the revocationDate.

Returns:: the revocation date.

hasExtensions

public abstract boolean hasExtensions()

Returns true if this CRL entry has extensions.

Returns:: true if this entry has extensions, false otherwise.

toString

public abstract String toString()

Returns a string representation of this CRL entry.

Overrides:: toString in class Object

Returns:: a string representation of this CRL entry.
