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 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.

---

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.

---

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.

---

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.
