Class HybridEncryptFactory

java.lang.Object

com.google.crypto.tink.hybrid.HybridEncryptFactory

public final class HybridEncryptFactory
extends Object

Static methods for obtaining HybridEncrypt instances.

Usage

 KeysetHandle keysetHandle = ...;
 HybridEncrypt hybridEncrypt = HybridEncryptFactory.getPrimitive(keysetHandle);
 byte[] plaintext = ...;
 byte[] contextInfo = ...;
 byte[] ciphertext = hybridEncrypt.encrypt(plaintext, contextInfo);
 

The returned primitive works with a keyset (rather than a single key). To encrypt a plaintext, it uses the primary key in the keyset, and prepends to the ciphertext a certain prefix associated with the primary key.

1.0.0
