     RCA is used for most standard public key/private key encryption techniques. Due to its burden on resources, RCA is generally used to encrypt random session keys wich are then used to encode messages with RC4. RCA also brings digital certificates into the picture. This, and many other "public" algorithms using RC4 do not truly make the message secure. Encryption is performed in 8 bit blocks - or 1 byte. Typing "AAAAAA", you will see a pattern begin for form with the encrypted data. If someone were to look at the results from encrypting each letter of the alphabet, your data would be compromized. Also, the public/private keys are limited between a range of 1 and about 65000. This is primarily a starting point if you want to enable a more secure encryption scheme, or you just want to learn more about it.

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.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
