the parameters encoded using their primary encoding format.

engineGetEncodedback to summary
protected byte[] engineGetEncoded(String format)

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.

engineInitback to summary
protected void engineInit(AlgorithmParameterSpec paramSpec) throws InvalidParameterSpecException

Implements abstract java.security.AlgorithmParametersSpi.engineInit.

Doc from java.security.AlgorithmParametersSpi.engineInit.

Initializes this parameters object using the parameters specified in paramSpec.

Parameters
paramSpec:AlgorithmParameterSpec

the parameter specification.

Exceptions
InvalidParameterSpecException:
if the given parameter specification is inappropriate for the initialization of this parameter object.

Parameters
params:byte[]

the encoded parameters.

format:String

the name of the decoding format.

Exceptions
IOException:
on decoding errors
