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.

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.

INVALID_INIT
This reason code is used to indicate that the signature or cipher object
has not been correctly initialized for the requested operation.
|
