* @brief This class provides methods for encryption and decryption using the Data Encryption Standard (DES) method.

- * @since 2.0
+ * @since 2.0
*
* The %DesCipher class provides a symmetric cipher using the Data Encryption Standard (DES) method.
- * Sets appropriate values for the requested mode/key bit/padding scheme and cipher operation mode
- * (CIPHER_ENCRYPT or CIPHER_DECRYPT) parameters. @n
+ * This class allows to set appropriate values for the requested mode/key bit/padding scheme and cipher operation mode
+ * (::CIPHER_ENCRYPT or ::CIPHER_DECRYPT) parameters. @n
*
* For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/security/ciphers.htm">Ciphers</a>.
*
* @since 2.0
*
* @return An error code
- * @param[in] transformation The name of the requested mode/key bit/padding scheme @n
+ * @param[in] transformation The requested mode/key bit/padding scheme @n
* For example, "CBC/NOPADDING" or "CBC/PKCS7PADDING".
* @param[in] opMode The cipher operation mode @n
* The valid values for %DesCipher are @c CIPHER_ENCRYPT and @c CIPHER_DECRYPT.
* @exception E_SUCCESS The method is successful.
- * @exception E_OUT_OF_MEMORY The memory is insufficient.
- * @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.
+ * @exception E_OUT_OF_MEMORY The memory is insufficient.
+ * @exception E_INVALID_ARG Either of the following conditions has occurred:
+ * - A specified input parameter is invalid.
+ * - The specified @c opMode does not contain a valid value for the cipher operation.
* @remarks If @c opMode is not matching the actual operation, the result of the operation is @c null and an exception is returned. @n
- * 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.
+ * 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.
