Protecting AVI files ...

P: n/a
Hi All,

I am developing a program in Visual Basic .NET 2002. There are some
videos in AVI format. For the protection of these AVI files i encrypted my
files with the use of DES algorithm in the system.security.cryptography
namespace. My program developed in VB.NET will have all the passwords for
these AVI files and my program only can open these files using the same
password. I used Windows Media Player control in my application to show
these AVI files. So the user should use my program to view these encrypted
AVI files.

How can i program in VB.NET so that my program will decrypt the AVI
file and show that AVI file in my program. While doing this the user should
not get a chance of stealing my videos either from the Temporary folder or
any other folder in my computer.

How can I do this? How can i protect my videos while decrypting and
showing in Windows Media Player?

Please help me.

With Regards,
Vanga Sasidhar
