Plus Extreme Encryption

Executive Overview of our Privacy Solution

  1. You have control of your files, your messages, your organization's knowledge base. No-one else has any access to your encryption keys, not even Marpex Inc.
  2. Our Automatic Keys system eliminates all the pain of key management.
  3. The solution is founded on a strong encryption technology with 2688 bit keys in the current version.
  4. When MarpX Extreme Encryption PETs (Private Exchange Tools) are added, the privacy solution becomes totally quantum resistant.
  5. The method can be scaled indefinitely so that it will remain fully quantum resistant well into the future.
  6. The technology can be applied to the Internet of Things.
  7. The technology has been published and source code can be made available to potential cybersecurity licensees.

The cybersecurity inventions by Marpex Inc. are intended as middleware to be included within the products of other firms, to improve their efficiency and security. To explore possibilities, please contact Steve Feher at 740 317-4847 or
