Class LegacyFullHybridDecrypt

java.lang.Object

com.google.crypto.tink.hybrid.internal.LegacyFullHybridDecrypt

All Implemented Interfaces:

HybridDecrypt

@Immutable
public final class LegacyFullHybridDecrypt
extends Object
implements HybridDecrypt

Takes an arbitrary raw HybridDecrypt and makes it a full primitive. This is a class that helps us transition onto the new Keys and Configurations interface, by bringing potential user-defined primitives to a common denominator with our primitives over which we have control.
