Interface PrivateKey

All Superinterfaces:
Key, Persistable, Persistable
All Known Implementing Classes:
DHPrivateKey, DSAPrivateKey, ECPrivateKey, KEAPrivateKey, RSAPrivateKey

public interface PrivateKey
extends Key

PrivateKey represents the idea of a private key, which is a key intended to be secret, and has an associated public key intended to be publically disclosed. The private key normally performs operations such as decryption and signing, whereas the public key performs operations such as encryption and verification.

verify

void verify()
            throws InvalidKeyException,
                   InvalidCryptoSystemException,
                   CryptoTokenException,
                   CryptoUnsupportedOperationException
Performs certain integrity checks on the private 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 real private key parameters.

Throws:
InvalidKeyException - Thrown if the specified key is improperly formatted or invalid.
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.
