Class Overview

This class implements the parameter set used with RC2 encryption, which is defined in RFC2268 as follows: 

 RC2-CBCParameter ::= CHOICE {
   iv IV,
   params SEQUENCE {
     version RC2Version,
     iv IV
   }
 }

 where

 IV ::= OCTET STRING -- 8 octets
 RC2Version ::= INTEGER -- 1-1024

public RC2Parameters ()

Protected Methods

protected byte[] engineGetEncoded ()

Returns the parameters in their primary encoding format. The primary encoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.

Returns
  • the parameters encoded using their primary encoding format.
Throws
IOException

protected byte[] engineGetEncoded (String encodingMethod)

Returns the parameters encoded in the specified format. If format is null, the primary encoding format for parameters is used. The primary encoding format is ASN.1, if an ASN.1 specification for these parameters exists.

Parameters
encodingMethod the name of the encoding format.
Returns
  • the parameters encoded using the specified encoding scheme.
Throws
IOException

protected AlgorithmParameterSpec engineGetParameterSpec (Class paramSpec)

Returns a (transparent) specification of this parameters object. paramSpec identifies the specification class in which the parameters should be returned. It could, for example, be DSAParameterSpec.class, to indicate that the parameters should be returned in an instance of the DSAParameterSpec class.

Parameters
paramSpec the the specification class in which the parameters should be returned.
Returns
  • the parameter specification.
Throws
InvalidParameterSpecException

protected void engineInit (byte[] encoded)

Imports the specified parameters and decodes them according to the primary decoding format for parameters. The primary decoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.

Parameters
encoded the encoded parameters.
Throws
IOException

protected void engineInit (byte[] encoded, String decodingMethod)

Imports the parameters from params and decodes them according to the specified decoding format. If format is null, the primary decoding format for parameters is used. The primary decoding format is ASN.1, if an ASN.1 specification for these parameters exists.

Parameters
encoded the encoded parameters.
decodingMethod the name of the decoding format.
Throws
IOException

protected void engineInit (AlgorithmParameterSpec paramSpec)

Initializes this parameters object using the parameters specified in paramSpec.

Parameters
paramSpec the parameter specification.
Throws
InvalidParameterSpecException

protected String engineToString ()

Returns a formatted string describing the parameters.

Returns
  • a formatted string describing the parameters.
