extends CardRuntimeException

CryptoException represents a cryptography-related exception.

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.
