What is MarpX Good Privacy?

MarpX Good Privacy is a free program that you may use to make messages and computer files private. This program and its files may be downloaded, ideally onto a flash drive. The flash drive may be plugged into a USB port on almost any Windows PC (Personal Computer, Windows 7 or later). Under best practices, the PC may be a surplus machine, preferably NOT connected to the Internet. If a dedicated Windows PC is used, then Apple, Unix, and Windows users alike may create and exchange encrypted (privatized) files and messages with assurance that eavesdroppers and hackers have little hope of breaking the privacy.


MarpX Good Privacy, MarpX Better Privacy, and Extreme Encryption™ are based on a new technology, for which patent application 15/816865 was submitted to the United States Patent and Trademark Office (USPTO) in November 2017. MarpX Good Privacy lets the user choose any combination of seven capital letters as a key to encrypt 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.


For encryption, seven capital letters are needed for a key. So there are 26 ways (A-Z) to choose each letter. There are 26 X 26 X 26 X 26 X 26 X 26 X 26 = 8,031,810,176 different combinations of seven capital letters. An encrypted file or message provides no clues as to what seven letters were used. That means 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.


Provided you know the right key, MarpX Good Privacy lets you decrypt files and messages that were encrypted by MarpX Good Privacy. As a special added feature, Marpx Good Privacy can also decrypt content secured by Marpx Better Privacy with keys containing upper case letters and/or lower case letters and/or numeric digits.


Neither Marpx Good Privacy nor Marpx Better Privacy can decrypt content protected by Extreme Encryption.
