Class DeterministicAeadKeyTemplates

java.lang.Object

com.google.crypto.tink.daead.DeterministicAeadKeyTemplates

public final class DeterministicAeadKeyTemplates
extends Object

Pre-generated KeyTemplate for DeterministicAead keys.

We recommend to avoid this class in order to keep dependencies small.

• Using this class adds a dependency on protobuf. We hope that eventually it is possible to use Tink without a dependency on protobuf.
• Using this class adds a dependency on classes for all involved key types.

These dependencies all come from static class member variables, which are initialized when the class is loaded. This implies that static analysis and code minimization tools (such as proguard) cannot remove the usages either.

Instead, we recommend to use KeysetHandle.generateEntryFromParametersName or KeysetHandle.generateEntryFromParameters. One can use these templates to generate new Keyset with KeysetHandle. To generate a new keyset that contains a single AesSivKey, one can do:

   Config.register(DeterministicAeadConfig.TINK_1_1_0);
   KeysetHandle handle = KeysetHandle.generateNew(DeterministicAeadKeyTemplates.AES256_SIV);
   DeterministicAead daead = handle.getPrimitive(DeterministicAead.class);

1.1.0
