Class RsaKemAlgorithmParameters

java.lang.Object

java.security.AlgorithmParametersSpi

iaik.security.rsa.RsaKemAlgorithmParameters

public class RsaKemAlgorithmParameters
extends java.security.AlgorithmParametersSpi

This class represents the Algorithm Parameters of the RsaKem.

According to ISO/IEC 18033-2 the encoding of RsaKemParameters has two components, namely:

     RsaKemParameters  ::= SEQUENCE {
             keyDerivationFunction ALGORITHM,
             keyLength KeyLength
     }

     KeyLength  ::= INTEGER(1..MAX)

Method Detail

engineInit

protected void engineInit(java.security.spec.AlgorithmParameterSpec paramSpec)
                   throws java.security.spec.InvalidParameterSpecException

Initializes the Algorithm Parameters with a respective instance of RsaKemAlgorithmParameterSpec. Every other type of AlgorithmParameterSpec will result in a thrown Exception.

Specified by:

engineInit in class java.security.AlgorithmParametersSpi

Parameters:

paramSpec - an instance of RsaKemAlgorithmParameterSpec

Throws:

java.security.spec.InvalidParameterSpecException - if the provided object is inappropriate to initialize the Algorithm Parameters.

engineInit

protected void engineInit(byte[] params)
                   throws java.io.IOException

Decodes an ASN.1 representation of RsaKem Algorithm Parameters.

Specified by:

engineInit in class java.security.AlgorithmParametersSpi

Parameters:

params - encoding of some parameters

Throws:

java.io.IOException - if the provided parameters are corrupt or not decodable by the implementation. Note that only ASN.1 is supported.

engineInit

protected void engineInit(byte[] params,
                          java.lang.String format)
                   throws java.io.IOException

Specified by:

engineInit in class java.security.AlgorithmParametersSpi

Throws:

java.io.IOException

engineGetParameterSpec

protected java.security.spec.AlgorithmParameterSpec engineGetParameterSpec(java.lang.Class paramSpec)
                                                                    throws java.security.spec.InvalidParameterSpecException

Specified by:

engineGetParameterSpec in class java.security.AlgorithmParametersSpi

Throws:

java.security.spec.InvalidParameterSpecException

engineGetEncoded

protected byte[] engineGetEncoded()
                           throws java.io.IOException

Specified by:

engineGetEncoded in class java.security.AlgorithmParametersSpi

Throws:

java.io.IOException

engineGetEncoded

protected byte[] engineGetEncoded(java.lang.String format)
                           throws java.io.IOException

Specified by:

engineGetEncoded in class java.security.AlgorithmParametersSpi

Throws:

java.io.IOException

engineToString

protected java.lang.String engineToString()

Specified by:

engineToString in class java.security.AlgorithmParametersSpi
