Class PublicKeyVerifyFactory

java.lang.Object

com.google.crypto.tink.signature.PublicKeyVerifyFactory

public final class PublicKeyVerifyFactory
extends Object

Static methods for obtaining PublicKeyVerify instances.

Usage

 KeysetHandle keysetHandle = ...;
 PublicKeyVerify verifier = PublicKeyVerifyFactory.getPrimitive(keysetHandle);
 verifier.verify(signature, data);
 

The returned primitive works with a keyset (rather than a single key). To verify a signature, the primitive uses the prefix of the signature to efficiently select the right key in the set. If there is no key associated with the prefix or if the keys associated with the prefix do not work, the primitive tries all keys with OutputPrefixType.RAW.
