Method Details

engineGetEncoded

protected byte[] engineGetEncoded()
                           throws IOException

Description copied from class: AlgorithmParametersSpi

Returns the parameters in their default encoding format. The default encoding format is ASN.1.

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Returns:

the encoded parameters.

Throws:

IOException - if this AlgorithmParametersSpi has already been initialized, or if this parameters could not be encoded.

engineGetEncoded

protected byte[] engineGetEncoded(String format)
                           throws IOException

Description copied from class: AlgorithmParametersSpi

Returns the parameters in the specified encoding format.

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Parameters:

format - the name of the encoding format.

Returns:

the encoded parameters.

Throws:

IOException - if this AlgorithmParametersSpi has already been initialized, or if this parameters could not be encoded.

localEngineGetParameterSpec

protected AlgorithmParameterSpec localEngineGetParameterSpec(Class paramSpec)
                                                      throws InvalidParameterSpecException

Specified by:

localEngineGetParameterSpec in class BaseAlgorithmParameters

Throws:

InvalidParameterSpecException

engineInit

protected void engineInit(AlgorithmParameterSpec paramSpec)
                   throws InvalidParameterSpecException

Description copied from class: AlgorithmParametersSpi

Initializes this AlgorithmParametersSpi with the specified AlgorithmParameterSpec.

Specified by:

engineInit in class AlgorithmParametersSpi

Parameters:

paramSpec - the parameter specification.

Throws:

InvalidParameterSpecException - if this AlgorithmParametersSpi has already been initialized or the given paramSpec is not appropriate for initializing this AlgorithmParametersSpi.

engineInit

protected void engineInit(byte[] params)
                   throws IOException

Description copied from class: AlgorithmParametersSpi

Initializes this AlgorithmParametersSpi with the specified byte[] using the default decoding format for parameters. The default encoding format is ASN.1.

Specified by:

engineInit in class AlgorithmParametersSpi

Parameters:

params - the encoded parameters.

Throws:

IOException - if this AlgorithmParametersSpi has already been initialized, or the parameter could not be encoded.

engineInit

protected void engineInit(byte[] params,
String format)
                   throws IOException

Description copied from class: AlgorithmParametersSpi

Initializes this AlgorithmParametersSpi with the specified byte[] using the specified decoding format.

Specified by:

engineInit in class AlgorithmParametersSpi

Parameters:

params - the encoded parameters.

format - the name of the decoding format.

Throws:

IOException - if this AlgorithmParametersSpi has already been initialized, or the parameter could not be encoded.

engineToString

protected String engineToString()

Description copied from class: AlgorithmParametersSpi

Returns a string containing a concise, human-readable description of this AlgorithmParametersSpi.
