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 CRLExtensions()

Default constructor.

CRLExtensionsback to summary
public CRLExtensions(DerInputStream in) throws CRLException

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

Parameters
in:DerInputStream

the DerInputStream to read the Extension from, i.e. the sequence of extensions.

Exceptions
CRLException:
on decoding errors.

Method Detail

deleteback to summary
public void delete(String alias)

Delete the extension value with this alias.

Parameters
alias:String

the identifier string for the extension to delete.

encodeback to summary
public void encode(DerOutputStream out, boolean isExplicit)

Encode the extensions in DER form to the stream.

Parameters
out:DerOutputStream

the DerOutputStream to marshal the contents to.

isExplicit:boolean
