CryptoException
represents a cryptography-related exception.
The API classes throw JCRE owned instances of SystemException
.
JCRE owned instances of exception classes are temporary JCRE Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components.
