Class CryptoException


public class CryptoExceptionextends CardRuntimeException

CryptoException represents a cryptography-related exception. TheAPIclasses 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.

Constructor Detail

CryptoException

public CryptoException(short reason)

Constructs a CryptoException with the specified reason. To conserve on resources use throwIt() to use the Java Card runtime environment-owned instance of this class.

Parameters:reason - the reason for the exception

Method Detail

throwIt

public static void throwIt(short reason)

Throws the Java Card runtime environment-owned instance of CryptoException 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 for the Java Card Platform, section 6.2.1 for details.

Parameters:reason - the reason for the exception

Throws: CryptoException- always
