public class CryptoException

extends CardRuntimeException

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.

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

ILLEGAL_VALUE

public static final short ILLEGAL_VALUE

This reason code is used to indicate that one or more input parameters is out of allowed bounds.

UNINITIALIZED_KEY

public static final short UNINITIALIZED_KEY

This reason code is used to indicate that the key is uninitialized.

NO_SUCH_ALGORITHM

public static final short NO_SUCH_ALGORITHM

This reason code is used to indicate that the requested algorithm or key type is not supported.

INVALID_INIT

public static final 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.

ILLEGAL_USE

public static final 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.

Constructor Detail

CryptoException

public CryptoException(short reason)

Constructs a CryptoException with the specified reason. To conserve on resources use throwIt() to use the JCRE owned instance of this class.

Parameters:

reason - the reason for the exception.

Method Detail

throwIt

public static void throwIt(short reason)

Throws the JCRE owned instance of CryptoException with the specified reason.

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. See Java Card Runtime Environment (JCRE) 2.1 Specification for details.

Parameters:

reason - the reason for the exception.

Throws:

CryptoException - always.
