     Authenticate(project1.vbp) and Authenticate Generator(AuthenticateGenerator.vbp) separate projects. I have seen many types of encryption protection, password protection programs to defeat the end users attempts at getting your software for free. One major problem with this type of protection is that users can copy and distribute to whomever they please. I created this program to overcome this problem. Authenticate requires to end user to call for an authentication number. (Note: This could be accomplished on the internet also if you have an internet site.) Once the user calls they give you a 20 character string which you type into the authentication generator, which in turn gives you a 20 character authentication string to provide the user. The user then enters that authentication number and he is registered. This number will only be valid for that particular computer. How does the program do this you ask? First the program reads the Serial Number from the hard drive. When a hard drive is formatted the operating system saves a random 32 bit number onto the disk as a serial number. This makes the serial number unique, or unique enough to prevent the software which you worked so hard to create from being distributed illegally. The program encrypts this serial number with 5 sophisticated algorithms. Any questions will be answered promptly. Don't forget to rate this program. All feedback welcome. Enjoy--

For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
