engineGetEncodedback to summary
protected final 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.

Returns:byte[]

the parameters encoded using their primary encoding format.

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

Parameters
format:String

the name of the encoding format.

Returns:byte[]

the parameters encoded using the specified encoding scheme.

Exceptions
IOException:
on encoding errors.
engineGetParameterSpecback to summary
protected final <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.

Parameters
<T>
the type of the parameter specification to be returned
paramSpec:Class<T>

the specification class in which the parameters should be returned.

Returns:T

the parameter specification.

Exceptions
InvalidParameterSpecException:
if the requested parameter specification is inappropriate for this parameter object.
engineInitback to summary
protected final void engineInit(byte[] encoding) throws IOException

Implements abstract java.security.AlgorithmParametersSpi.engineInit.

Doc from java.security.AlgorithmParametersSpi.engineInit.

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
encoding:byte[]

the encoded parameters.

Exceptions
IOException:
on decoding errors
engineInitback to summary
protected void engineInit(byte[] params, String format) throws IOException

Implements abstract java.security.AlgorithmParametersSpi.engineInit.

Doc from java.security.AlgorithmParametersSpi.engineInit.

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
params:byte[]

the encoded parameters.

format:String

the name of the decoding format.
