com.google.crypto.tink.mac.MacKeyTemplates

public final class MacKeyTemplates
extends Object

Pre-generated KeyTemplate for Mac.

One can use these templates to generate new Keyset with KeysetHandle. To generate a new keyset that contains a single HmacKey, one can do:

 Config.register(Mac.TINK_1_0_0);
 KeysetHandle handle = KeysetHandle.generateNew(MacKeyTemplates.HMAC_SHA256_128BITTAG);
 Mac mac = MacFactory.getPrimitive(handle);
 

Since:

1.0.0
