public interface PublicKey
extends Key

PublicKey is an interface which represents the idea of a public key.

A public key is a key intended to be publicly available (not secret) which has an associated private key intended to be secret. The public key normally performs operations such as encryption and verification, where as the private key performs operations such as decryption and signing.

verify

void verify()
            throws InvalidKeyException,
                   InvalidCryptoSystemException,
                   CryptoTokenException,
                   CryptoUnsupportedOperationException

Performs certain integrity checks on the public key parameters. These checks are useful to prevent certain types of attacks that involve modifying the parameters and then using a signed message to calculate the private key parameters.

Throws:

InvalidKeyException - Thrown if the specified key is invalid or malformed.

InvalidCryptoSystemException - Thrown if the specified crypto system is invalid.

CryptoTokenException - Thrown if an error occurs with the crypto token or the crypto token is invalid.

CryptoUnsupportedOperationException - Thrown if a call is made to an unsupported operation.
