MarpX Privacy™ is a program installed on a flash drive, used to make messages and computer files fully private. The flash drive may be plugged into a USB port on almost any Windows PC (Personal Computer). Under best practices, the PC may be a surplus machine, preferably NOT connected to the Internet. Apple, Unix, and Windows users alike may create and exchange encrypted (private) and decrypted (back-to-original) files and messages with assurance that eavesdroppers and hackers have little to no hope of breaking the privacy.
MarpX Privacy™ and Extreme Encryption™ both are based on a new technology, for which patent application 15816865 was submitted to the United States Patent and Trademark Office (USPTO) in November 2017. MarpX Privacy™ lets the user choose any combination of seven letters as a key for a message or file. The person who is intended as receiver will need the same seven letter key to restore the original content. The sender may choose the same key for successive messages and files, but it is more secure to choose a different key each time.
Seven letters are needed for a key. Capital letters and lower case letters are treated as the same. So there are 26 ways (A-Z) to choose each letter. To choose all seven letters, there are 26 X 26 X 26 X 26 X 26 X 26 X 26 = 8,031,810,176 different combinations. There are no patterns in the privatized (encrypted) version, so a hacker would on average have to try at least half of the eight billion possible keys. The word "try" here means that the hacker would have to go all the way through every stage of a key before knowing whether it may be the right key. It would take a long, long time and/or some fantastic decryption tools to find the key. And that's for just one file or message. The next one likely has a different key.
If that's not secure enough, there's always our Extreme Encryption™ product.
Almost every flash drive that we mail out contains a full set of MarpX Privacy™ -- software, helps, control files, etc. The purchaser is authorized to copy MarpX Privacy™ onto a separate flash drive for any resident of the United States or Canada. Provided copies are accurate, copies may be made of those copies. And so on. Why do we encourage free copying? Because we believe that privacy is essential to the dignity of every human being. MarpX Privacy™ is our little contribution to your dignity and your freedom to control which personal information you choose and choose not to share.
Want MarpX Privacy™ free? Take a flash drive to someone who has a good up-to-date copy. Here is how to make a copy.
Want it at low cost? Purchase your own flash drive at our online store.
Want it nearly free? Chip in with some friends to order a flash drive from our online store.
Whatever way you get your copy, be nice! Share it readily with others. We ask only that each copy be an accurate and complete set of the essential files.
Certainly a download version would be more convenient than delivery on a flash drive. Reasons why we don't offer a download:
- Far and away the most important reason is United States law, in the form of the Export Administration Regulations of the Department of Commerce's Bureau of Industry and Security. Export of strong encryption software from the United States is severely restricted. Assuming MarpX Privacy™ qualifies under (forgive the gobbledegook) "ECCN 5A002", export to Canada is allowed. But that's all. So we mail flash drives as a way of ensuring that the software goes out only to U.S. and Canadian addresses.
- Downloads are normally meant only for only one or a very few computers. In contrast, by using a flash drive, MarpX Privacy™ can be used on almost any Windows PC that is handy.
- For greatest security, MarpX Privacy™ is used on a Windows PC that is not connected to the Internet. There is no way to download anything onto a computer that is not connected.
