Encrypt Decrypt Vb6 Source Code

Class: Encryption in Category General VBA/VB6: Encryption and Compression from Total Visual SourceBook Encrypt and decrypt files and strings with Unicode support using XOR password encryption in VBA and VB6. The password is also encrypted as the string or file is processed, providing an additional level of security. Can anyone please tell me how to hide source code of a website. I need it very desperately:crazy. Des Encrypt Codes and Scripts Downloads Free. With AspEncrypt, you can encrypt and decrypt files and messages using industry-standard ciphers such as RC2 or DES. This program interactively lets you. The following Visual Basic project contains the source code and Visual Basic examples used for encrypt/decrypt string.

Introduction

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.

I've put together an Encryption Demo program that demonstrates how to encrypt and decrypt documents using the following encryption classes:

AES (Advanced Encryption Standard)
DES (Data Encryption Standard)
RC2 ('Ron's Code' or 'Rivest Cipher')
Rijndael
Triple DES (Triple Data Encryption Standard)

This application uses persistent keys in combination with the respective algorithms to encrypt and decrypt data.

Using the code

Pass the selected file to the Encrypt and Decrypt methods below
Declare the instance of the AES class that will be used to encrypt and decrypt
The code for the Encrypt Method
The code for the Decrypt Method
Persisted Key and Vector (IV)

Points of Interest

The process for encrypting and decrypting each of the different algorithms is the same. One of the things you will find different is the number of bytes that are used in the different key and vector arrays.

Hopefully this demo is helpful to you!
