Class LegacyFullHybridEncrypt

java.lang.Object

com.google.crypto.tink.hybrid.internal.LegacyFullHybridEncrypt

All Implemented Interfaces:

HybridEncrypt

@Immutable
public final class LegacyFullHybridEncrypt
extends Object
implements HybridEncrypt

Takes an arbitrary raw HybridEncrypt 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.

Method Summary

Modifier and Type	Method and Description
static HybridEncrypt	create(LegacyProtoKey key) This method covers the cases where users created their own aead/key classes.
byte[]	encrypt(byte[] plaintext, byte[] contextInfo) Encryption operation: encrypts plaintext binding contextInfo to the resulting ciphertext.
