How your order arrives

Place orders for Private Exchange Tools (PETs) at https://BuyExtremeEncryption.com. When you place your first order, you will be asked the normal questions to support a business transaction. In addition, you will be asked to create a secure seven character key (any combination of capital letters, lower case letters and/or numeric digits). Depending on your order, your supply will arrive either electronically or by mail on a flash drive. Your first order normally takes one extra business today so that we can check your eligibility. You must be in the United States, not a national of a country under U.S. government sanctions, and not personally or part of an entity on the U.S. Consolidated Screening List.

 

Your first order will include one extra PET at no charge. You will be asked to use that PET in a new entry to the roster, with Marpex Inc. as the fellow confidant and the seven character code above as the authentication code. With that confidant relationship in place, we can fulfil your subsequent orders with Extreme Encryption™ security.

 

Unless you order otherwise, your PETs will be in batches of up to one thousand units. Each batch is a self-executing ZIP file which has been encrypted. On the first order, use the same seven character code as above to decrypt the batches. In later orders, use Automatic Keys and the Marpex Inc. confidant relationship to decrypt your batch(es) of PET files.

 

Once decrypted, the batches may be broken into their individual PETs by double clicking on the self-extracting file.

Secure handling and redistribution

When your order arrives, best practice is to set it up using a computer that is not connected to the Internet. If you are unable to do that, at least use a computer with strong anti-piracy protection and extract your new PET files onto a USB flash drive (or some equivalent). The aim is to minimize the exposure of unencrypted PET files as a precaution against infiltration by malevolent persons.

 

If you ordered a flash drive, it has the entire Marpx Privacy program and support files already in place. You are free to make copies of this flash drive for others. The one precaution is to pass along to others only the PET files that they will individually need for themselves and/or to pass along to their prospective confidants. Think security!

Shared PETs and shared authentication codes

Encrypt any PET file that may be at risk when transmitted. Ensure that all recipients understand the security need. They will all need to be aware of how to Set Up To Share Confidential Matters. This includes arranging to share confidant authentication codes for each relationship by some offline method, best face to face, alternatively by telephone or other means.

Install = add a new roster entry

When a PET is used within a new roster entry, it must at that moment be unencrypted. Since confidant relationships would not yet be in place, manual keys might be needed to decrypt the PET file.

 

From there, each participant should follow the instructions of how to Add a New Roster Entry.

What winds up where?

When you add a new entry to the roster, the PET file (if any) is automatically encrypted and stored in a sub-directory named PETs within the MarpxPrivacy set of program and support files. You can at this point delete the unencrypted PET file, or at a minimum store it offline in a secure place.

 

The roster is re-encrypted every time there is the least change in it -- new entry added, entry edited, or entry deleted. Roster.txt.enc resides in the MarpxPrivacy directory.
