Class X509CRLEntry

java.lang.Object
java.security.cert.X509CRLEntry
All Implemented Interfaces:
X509Extension
public abstract class X509CRLEntry 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
 }

  • Constructor Details

    • X509CRLEntry

      public X509CRLEntry()
      Constructor for subclasses to call.

  • Method Details

    • 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.

      Object.hashCode(), HashMap

    • 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), System.identityHashCode(java.lang.Object)

    • 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.

    • getRevocationReason

      public CRLReason getRevocationReason()
      Returns the reason the certificate has been revoked, as specified in the Reason Code extension of this CRL entry.
      Returns:
      the reason the certificate has been revoked, or null if this CRL entry does not have a Reason Code extension
