Static methods and constants for registering with the Registry all instances of PublicKeySign and PublicKeyVerify key types supported in a particular release of Tink. 
To register all PublicKeySign and PublicKeyVerify key types provided in the latest Tink
version one can do:

SignatureConfig.init();
