| الملخص: | In this project, a message handler with security features is developed using
Microsoft CryptoAPI. The source code is written in Visual Basic to take advantage
of the extensive graphical features of the language. A Visual Basic module called
clsCiyptoAPI was developed to make calls to the advapi32.dll where the functions
for the CryptoAPI reside. This module comprises seven routines, which are; a
ByteToArray routine, ConvertByteToHex routine, ConvertStringFromHex routine,
ConvertStringtoHex routine, CreateHash routine, CiyptEncrypt routine, and
CryptDecrypt routine. These routines were compiled together to form the Dynamic
Link Library (DLL) file. This dll file serves as a reference for any Visual Basic
application which needs to call the CtyptoAPI function. A simple application is also
developed to illustrate how to use this module to develop the user applications. This
application demonstrates how to hash, encrypt and decrypt the string and various
types of files using several cryptography algorithms provided by the CiyptoAPI
function. This project also shows how to use a cryptography technique in network
systems. |
