protected abstract void engineInit(AlgorithmParameterSpec paramSpec) throws InvalidParameterSpecException
paramSpec
.
paramSpec
- the parameter specification.
protected abstract void engineInit(byte[] params) throws IOException
params
- the encoded parameters.
protected abstract void engineInit(byte[] params, String format) throws IOException
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.
params
- the encoded parameters.
format
- the name of the decoding format.
protected abstract AlgorithmParameterSpec engineGetParameterSpec(Class paramSpec) throws InvalidParameterSpecException
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.
paramSpec
- the the specification class in which
the parameters should be returned.
protected abstract byte[] engineGetEncoded() throws IOException
protected abstract byte[] engineGetEncoded(String format) throws IOException
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.
format
- the name of the encoding format.
protected abstract String engineToString()
