Class Overview

This class defines the CRL Extensions. It is used for both CRL Extensions and CRL Entry Extensions, which are defined are follows: 

 TBSCertList  ::=  SEQUENCE  {
    version              Version OPTIONAL,   -- if present, must be v2
    signature            AlgorithmIdentifier,
    issuer               Name,
    thisUpdate           Time,
    nextUpdate           Time  OPTIONAL,
    revokedCertificates  SEQUENCE OF SEQUENCE  {
        userCertificate         CertificateSerialNumber,
        revocationDate          Time,
        crlEntryExtensions      Extensions OPTIONAL  -- if present, must be v2
    }  OPTIONAL,
    crlExtensions        [0] EXPLICIT Extensions OPTIONAL  -- if present, must be v2
 }

Public Constructors

public CRLExtensions ()

Default constructor.

public CRLExtensions (DerInputStream in)

Create the object, decoding the values from the passed DER stream.

Parameters
in the DerInputStream to read the Extension from, i.e. the sequence of extensions.
Throws
CRLException on decoding errors.

Public Methods

public void delete (String alias)

Delete the extension value with this alias.

Parameters
alias the identifier string for the extension to delete.

public void encode (OutputStream out, boolean isExplicit)

Encode the extensions in DER form to the stream.

Parameters
out the DerOutputStream to marshal the contents to.
isExplicit the tag indicating whether this is an entry extension (false) or a CRL extension (true).
Throws
CRLException on encoding errors.

public boolean equals (Object other)

Compares this CRLExtensions for equality with the specified object. If the other object is an instanceof CRLExtensions, then all the entries are compared with the entries from this.

Parameters
other the object to test for equality with this CRLExtensions.
Returns
  • true iff all the entries match that of the Other, false otherwise.

public Extension get (String alias)

Get the extension with this alias.

Parameters
alias the identifier string for the extension to retrieve.

public Collection<Extension> getAllExtensions ()

Return a collection view of the extensions.

Returns
  • a collection view of the extensions in this CRL.

public Enumeration<Extension> getElements ()

Return an enumeration of the extensions.

Returns
  • an enumeration of the extensions in this CRL.

public boolean hasUnsupportedCriticalExtension ()

Return true if a critical extension is found that is not supported, otherwise return false.

public int hashCode ()

Returns a hashcode value for this CRLExtensions.

Returns
  • the hashcode value.

public void set (String alias, Object obj)

Set the extension value with this alias.

Parameters
alias the identifier string for the extension to set.
obj the Object to set the extension identified by the alias.

public String toString ()

Returns a string representation of this CRLExtensions object in the form of a set of entries, enclosed in braces and separated by the ASCII characters ", " (comma and space).

Overrides to toString method of Object.

Returns
  • a string representation of this CRLExtensions.
