     This has been updated in a new post on June 4, 2001. Please see that posting for the latest code. This class serves as a wrapper for the Microsoft CryptoAPI (Base CSP) and the Zlib compression dll. It handles all government & business compression, encryption and signature needs, without yet another "look at my new kewl encryption code" (yawn) which is breakable by any gov't agency or professional cryptographer. This latest version now shows you how to do public/private key encryption and signatures. Took 2 solid weeks to research, code and debug this code, so put it to good use. Fully commented. Includes example program to demostrate each function's use.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. 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
