Method Detail

engineGetParameterback to summary
protected Object engineGetParameter(String param) throws InvalidParameterException

Implements abstract java.security.SignatureSpi.engineGetParameter.

Doc from java.security.SignatureSpi.engineGetParameter.

Gets the value of the specified algorithm parameter. This method supplies a general-purpose mechanism through which it is possible to get the various parameters of this object. A parameter may be any settable parameter for the algorithm, such as a parameter size, or a source of random bits for signature generation (if appropriate), or an indication of whether to perform a specific but optional computation. A uniform algorithm-specific naming scheme for each parameter is desirable but left unspecified at this time.

protected void engineSetParameter(String param, Object value) throws InvalidParameterException

Implements abstract java.security.SignatureSpi.engineSetParameter.

Doc from java.security.SignatureSpi.engineSetParameter.

Sets the specified algorithm parameter to the specified value. This method supplies a general-purpose mechanism through which it is possible to set the various parameters of this object. A parameter may be any settable parameter for the algorithm, such as a parameter size, or a source of random bits for signature generation (if appropriate), or an indication of whether to perform a specific but optional computation. A uniform algorithm-specific naming scheme for each parameter is desirable but left unspecified at this time.
