Now in this article, we will create a program in VB6.0 that will encrypt and decrypt a text. Now, let's start this tutorial! 1.Let's start this tutorial by following the following steps in Microsoft Visual Basic 6.0: Open Microsoft Visual Basic 6.0, click Choose Standard EXE, and click Open. 2.Next, add two Buttons named Command1 and labeled.

- Encryption is the processes of transforming electronic data from a 'plain text' state to an unreadable state by use of a cipher, also known as a algorithm. Although formerly pretty complex, encryption can now be implemented very easily in any.Net application using the various encryption classes in the System.Security.Cryptography namespace.
- The following VB.NET project contains the source code and VB.NET examples used for Encrypt decrypt file and save with any extension.
This article will describe how to encrypt and decrypt a file in java. We shall demonstrate file encryption using example source code.This source code has been tested to work not only on text files but also on audio video files and images.The name of the file, encrypt/decrypt and the password to be used for the encryption shall be passed as arguments to the .jar file.
This encryption occurs by writing encrypted data back to the place from where it was read,thus after encryption there is no trace of non encrypted data on your disk. The program doesn’t leave the non encrypted data on the disk by creating a new encrypted file,instead writes the encrypted data back from where read.This is accomplished by the use of random access file and filepointers.
Thus file recovery softwares will not be able to recover the plain non encrypted files from the disk.
Source code of the Encrypter Class
Vb6 Source Code Example
The encrypter class has a Encrypt function which accepts the source file name and the password as arguments. the function produces the encrypted file with a the same name but a .enc extension appended to the filename.
In the next page you will read about the source code of the main class and passing of the file name and other arguments to the .jar file
