Class PublicKeySignFactory

java.lang.Object

com.google.crypto.tink.signature.PublicKeySignFactory

public final class PublicKeySignFactory
extends Object

Static methods for obtaining PublicKeySign instances.

Usage

 KeysetHandle keysetHandle = ...;
 PublicKeySign signer = PublicKeySignFactory.getPrimitive(keysetHandle);
 byte[] data = ...;
 byte[] signature = signer.sign(data);
 

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

1.0.0
