Class MacKeyTemplates

java.lang.Object

com.google.crypto.tink.mac.MacKeyTemplates

Deprecated.

use the key template methods in the key managers, e.g., HmacKeyManager.hmacSha256HalfDigestTemplate().

@Deprecated
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 = handle.getPrimitive(Mac.class);
 

Since:

1.0.0
