Class CryptoException

  java.lang.Throwable
      java.lang.Exception
          java.lang.RuntimeException

All Implemented Interfaces:: Serializable

public class CryptoException
extends CardRuntimeException
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.

Field Summary
`static short`	`ILLEGAL_USE` This reason code is used to indicate that the signature or cipher algorithm does not pad the incoming message and the input message is not block aligned.
`static short`	`ILLEGAL_VALUE` This reason code is used to indicate that one or more input parameters is out of allowed bounds.
`static short`	`INVALID_INIT` This reason code is used to indicate that the signature or cipher object has not been correctly initialized for the requested operation.
`static short`	`NO_SUCH_ALGORITHM` This reason code is used to indicate that the requested algorithm or key type is not supported.
`static short`	`UNINITIALIZED_KEY` This reason code is used to indicate that the key is uninitialized.

Constructor Summary
`CryptoException(short reason)` Constructs a `CryptoException` with the specified reason.

Method Summary
`static void`	`throwIt(short reason)` Throws the Java Card runtime environment-owned instance of `CryptoException` with the specified reason.

Method Detail

throwIt

public static void throwIt(short reason)

Throws the Java Card runtime environment-owned instance of CryptoException with the specified reason.

Parameters:: reason - the reason for the exception
Throws:: CryptoException - always
