MarpxPrivacy -- FREE

MarpxPrivacy is a Windows program, totally free to anyone in the world. It encrypts any file or message you want to send privately over the Internet or store in the cloud. Nobody can read it other that the intended recipients. If a hacker is after your files and messages, or if an autocratic government wants surveillance of your thoughts and loyalties, here is some rather good protection. Using ordinary equipment, and trying a possible key every second, it would take 111,000 years for someone to break through the protection of one message or file... and another 111,000 years to break the next one. If the bad guys have lots of smarts and massively powerful computer equipment that could try a million keys a second, it would still take forty days and forty nights for them to get access to even one file or message. In other words, MarpxPrivacy makes it too expensive to get at your stuff. As for mass surveillance, forget it; no hacker and no regime can afford that any more.

MarpX Extreme Encryption™ Licenses

In the United States there are organizations that might want something stronger. No problem, our U.S. Patent # 10,505,715 provides that too. Forget measuring hacking time in years, measure instead in lifetimes of the universe. Marpx Extreme Encryption™ licenses are delivered in the form of Private Exchange Tool (PET) files. One file and under a minute of set up time provides you with a private sharing relationship for decades to come, and -- note this -- with no worry about keys. (Actually, automatic keys are featured in the free program as well.) Click here to learn what to expect and then see the license purchase options. Note that under the Bureau of Industry and Security's Export Administration Regulations, the paid product is not currently for export from the United States.
