38 * @brief This class provides methods for encryption and decryption using the Data Encryption Standard in the Encrypt-Decrypt-Encrypt (DES-EDE) mode.
42 * The %DesEdeCipher class provides symmetric cipher using the Data Encryption Standard in the Encrypt-Decrypt-Encrypt (DES-EDE) mode.
43 * Sets appropriate values for the requested mode/key bit/padding scheme and cipher operation (CIPHER_ENCRYPT or CIPHER_DECRYPT) parameters. @n
45 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/security/ciphers.htm">Ciphers</a>.

58 * The object is not fully constructed after this constructor is called. For full construction, @n
59 * the Construct() method must be called right after calling this constructor.
66 * This destructor overrides Tizen::Base::Object::~Object().

77 * @return An error code
78 * @param[in] transformation The name of the requested mode/key bit/padding scheme @n
79 * For example, "CBC/NOPADDING" or "CBC/PKCS7PADDING".
80 * @param[in] opMode The cipher operation mode @n
81 * The valid values for %DesEdeCipher are @c CIPHER_ENCRYPT and @c CIPHER_DECRYPT.
82 * @exception E_SUCCESS The method is successful.
83 * @exception E_OUT_OF_MEMORY The memory is insufficient.
84 * @exception E_INVALID_ARG A specified input parameter is invalid, or the specified @c opMode does not contain a valid value for the cipher operation.
85 * @remarks If @c opMode is not matching the actual operation, the result of the operation is @c null and an exception is returned. @n
86 * For example, if @c opMode is set to @c CIPHER_ENCRYPT, @c CIPHER_WRAP, or @c CIPHER_UNWRAP and the DecryptN() method is used, then the result obtained is @c null and an exception is returned.
