public class OCSPExtensions

extends X509Extensions

Extends class X509Extensions for handling OCSP extensions.

This class can be used in the same way as the parent X509Extensions class for managing extensions that may be included in OCSP requests or responses. An application wishing to implement some private OCSP extension has to write a class by extending the abstract class V3Extension and statically registering the implemention by its object id:

This class consits of two parts:

• a static part: is responsible for registering implementations of extensions
• a dynamic part: manages the extensions

Every class which implements a specific extension must first register itself, e.g.:

 MyPrivateExtension extens V3Extension {
   ...
   public static final ObjectID oid = ...;

 }

 OCSPExtensions.register(MyPrivateExtension.oid, MyPrivateExtension.class);
 

Per default all OCSP extensions specified by RFC 2560 are implementend and registered by this class:

• AcceptableResponses
• ArchiveCutoff
• CrlID
• Nonce
• ServiceLocator

Constructor Detail

OCSPExtensions

public OCSPExtensions()

Default Constructor. Creates a new OCSPExtensions object to be supplied with V3Extensions.

OCSPExtensions

public OCSPExtensions(ASN1Object extensions)
               throws X509ExtensionException

Creates a new OCSPExtensions object from an ASN1Object.

The given ASN1Object has the ASN.1 type "SEQUENCE of Extensions", and may have been created by calling the toASN1Objetct method.

Parameters:

extensions - the extensions as ASN1Object

Throws:

X509ExtensionException - if the extensions cannot be parsed

Method Detail

getExtension

public V3Extension getExtension(ObjectID oid)
                         throws X509ExtensionInitException

Returns a particular extension, specified by its object ID.

This method creates a new implementation of the class registered for this ObjectID and initializes it with its extension value. If the extension is an unknown extension, an UnknownExtension is returned. If the extension cannot be initialized properly because of some error, an X509ExtensionInitException is thrown.

Overrides:

getExtension in class X509Extensions

Parameters:

objectID - the object ID of the extension

Returns:

the desired extension if it is available, or null if not

Throws:

X509ExtensionInitException - if the extension can not be initialized

toASN1Object

public ASN1Object toASN1Object()
                        throws X509ExtensionException

Returns this OCSPExtensions object as (SEQUENCE) ASN1Object. The ASN1Object has the ASN.1 type "SEQUENCE of Extensions".

Overrides:

toASN1Object in class X509Extensions

Returns:

the extensions as ASN1Object.

Throws:

X509ExtensionException - if the extensions could not be created
