Method Detail

engineGetEncodedback to summary
protected byte[] engineGetEncoded() throws IOException

Implements abstract java.security.AlgorithmParametersSpi.engineGetEncoded.

Doc from java.security.AlgorithmParametersSpi.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.

Exceptions
IOException:
on encoding errors.
engineGetEncodedback to summary
protected byte[] engineGetEncoded(String encodingMethod) throws IOException

Implements abstract java.security.AlgorithmParametersSpi.engineGetEncoded.

Doc from java.security.AlgorithmParametersSpi.engineGetEncoded.

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.

Exceptions
IOException:
on encoding errors.
engineGetParameterSpecback to summary
protected <T extends AlgorithmParameterSpec> T engineGetParameterSpec(Class<T> paramSpec) throws InvalidParameterSpecException

Implements abstract java.security.AlgorithmParametersSpi.engineGetParameterSpec.

Doc from java.security.AlgorithmParametersSpi.engineGetParameterSpec.

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.

Exceptions
InvalidParameterSpecException:
if the requested parameter specification is inappropriate for this parameter object.
