Method Detail

init

public void init(AlgorithmParameterSpec paramSpec)
          throws InvalidParameterSpecException

Initialize this parameters object using the specified parameters. Currently, only PBEParameterSpec is supported as specification type.

Overrides:

init in class AlgorithmParameters

Parameters:

paramSpec - the parameter specification

Throws:

InvalidParameterSpecException - if the parameter specification is not an instance of PBEParameterSpec.

init

public void init(byte[] enc)
          throws java.io.IOException

Import the specified parameters and decodes them according to the primary decoding format (ASN.1) for parameters.

Overrides:

init in class AlgorithmParameters

Parameters:

enc - the encoded parameters

Throws:

java.io.IOException - on decoding errors.

init

public void init(byte[] enc,
                 java.lang.String format)
          throws java.io.IOException

Import the specified parameters and decodes them according to the specified decoding format. If format is null, the primary decoding format for parameters (ASN.1) is used. Currently, only the default decoding format is supported.

Overrides:

init in class AlgorithmParameters

Parameters:

enc - the encoded parameters

format - the decoding format

Throws:

java.io.IOException - on decoding errors.

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

Return the parameters in their primary encoding format. The primary encoding format for parameters is ASN.1.

Overrides:

getEncoded in class AlgorithmParameters

Returns:

the ASN.1 encoded parameters

Throws:

java.io.IOException - on encoding errors.

getEncoded

public byte[] getEncoded(java.lang.String format)
                  throws java.io.IOException

Return the parameters in the specified encoding format. If format is null, the primary encoding format for parameters (ASN.1) is used. Currently, only the default encoding format is supported.

Overrides:

getEncoded in class AlgorithmParameters

Parameters:

format - the encoding format

Returns:

the ASN.1 encoded parameters

Throws:

java.io.IOException - on encoding errors.

getParameterSpec

public AlgorithmParameterSpec getParameterSpec(java.lang.Class paramSpec)
                                        throws InvalidParameterSpecException

Return a transparent specification of this parameters object. Currently, only PBEParameterSpecis supported as specification type.

Overrides:

getParameterSpec in class AlgorithmParameters

Parameters:

paramSpec - the the specification class in which the parameters should be returned

Returns:

the parameter specification

Throws:

InvalidParameterSpecException - if the parameter specification type is not assignable from PBEParameterSpec.

toString

public java.lang.String toString()

Overrides:

toString in class AlgorithmParameters

Returns:

a human readable form of the parameters
