Class JSSOAEPParameterSpec

java.lang.Object

org.mozilla.jss.util.NativeEnclosure

org.mozilla.jss.crypto.JSSOAEPParameterSpec

All Implemented Interfaces:

java.lang.AutoCloseable, java.security.spec.AlgorithmParameterSpec

public class JSSOAEPParameterSpec
extends NativeEnclosure
implements java.security.spec.AlgorithmParameterSpec

This class is utilized by JSS to implement OAEP support. Unlike the existing OAEPParameterSpec in the JCA, this class supports NativeEnclosure, allowing it to be used within low-level JNI calls. We support copying from an existing OAEPParameterSpec instance (so use is interchangeable within JSS) and support setting members from JSS-specific types. Note that this class cannot be used with other JCA providers natively.
