Free Visual Basic .Net, VB6 and C# source code download of Text and Database Encrypter, Encryption Decryption Source Code, XOR Encryption Project Downalod
XOR Based text and Database Encryption and Decryption
utility program written in Visual Basic. Click here to
Download the source code.
Introduction
Encrypt the text file and MS
Access Database by using XOR Encryption
technique. It Find each character from supplied
text and XOR each character with supplied
Encryption Key. More details use read me file in
source code folder after download.
This XOR encryption,
decryption program source code written in Visual
Basic 6 programming language is capable of
encrypt and decrypt text file and MS Access
database. This is a utility program, you can
easily integrated it with your main
application.
Screen shot
Logics
This program run on XOR technique. If we XOR two value
say A, B it will give a third value say C, If we again XOR A
with C it will return B. That is the logics.
65 XOR 160
= 225
1000001 XOR 10100000 = 11100001
225 XOR 160 = 65
11100001 XOR 10100000 =
1000001
Rest of the program is very
simple, We load a text file into first text box and XOR each
and every character by the Encryption function it takes two
argument one is KyCode which is numeric value possible value
from 1 to 255 however if you want to display encrypted text
set a range from 150 to 200, because no printing character
will not display properly. Second argument is String Input.

Here I am giving you sample
code how to encrypt and decrypt MS Access Database, If you
understand the logics you can encrypt and decrypt any type
of databases like SQL Server, Oracle. You can only encrypt
and decrypt Text or Varchar field.
Download the source code and project files
It is free to download,
source code are well commented, complete visual
basic source code can be download from the
download link. I did not claim any copyright for
this XOR encryption, decryption program and
source code. You can freely download this XOR
encrypt, decrypt program and use all or part of
this program as you want. This is tested and
live project visual basic source code however,
my advice to you that you should take a backup of your original
text file or database file before use this XOR
encryption, decryption program. This XOR
encryption and decryption VB program is based on
ASCII code, we need to pass same code for both
encrypt and decrypt process.
