public class CryptoException extends CardRuntimeException
CryptoException
represents a cryptography-related exception.The API classes throw Java Card runtime environment-owned instances of
CryptoException
.Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment 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.

throwIt
public static void throwIt(short reason)
Throws the Java Card runtime environment-owned instance ofCryptoException
with the specified reason.Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment 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. See Runtime Environment Specification, Java Card Platform, Classic Edition, section 6.2.1 for details.
