PGP (Pretty Good Privacy) is a higher level of encryption that ensures that no one but the intended recipient is able to access your data, making it suitable if you’re sharing highly sensitive data. It uses one key to encrypt the file (the public key) and another to decrypt (the private key) which traditionally makes it much more cumbersome to use than standard levels of encryption.

Preconditions for PGP

There are the following two preconditions for PGP encrypted file sharing:

  1. The Admin should enable PGP Encryption on the Service Settings sub-tab of the Administration tab. 
  2. PGP keys (Private and Public) should be generated. 

Admin can enable/disable PGP for all users on the Administration tab.

Who can share PGP files?

Any Quatrix® user can send PGP encrypted files to other users within one Quatrix account.

The administrator and user can share PGP encrypted files with contacts, whilst contacts can only decrypt, download and return encrypted files.

PGP Key Generation

PGP uses a pair of keys - the public key locks; the private key unlocks. So when sharing files with your users or contacts you’ll be encrypting with their public key and when you are acquiring files from your users the files get encrypted with your public key.

Info
titleKey Security
Your keys are securely stored on the Quatrix platform, additionally all private keys are encrypted using your passphrase. The passphrase is not stored or remembered by Quatrix which gives you peace of mind that no one (and that includes Quatrix staff), can ever decrypt files in transit or at rest.


Public Key Generation

The admin or user should generate PGP keys (in the Edit Profile) at first

and then request another pair of keys from the intended recipient - send PGP key generation request. 

You can send a request to a user or contact while adding or editing them and by selecting the Request PGP Keys icon on the Contacts or Administration tab.

Private Key Generation 

When the sender selects the Request PGP Keys check box, the recipient gets an email with the link to generate PGP keys. The recipient follows the link and generates PGP keys.

Once PGP keys are generated, a confirmation email will be sent to the sender of the request.

Warning

If you forget your passphrase, you won’t be able to share encrypted files anymore!

Encrypting and Decrypting Files 

Encrypting folders and files is a way to protect them from unwanted access. There are a few simple steps to share and acquire files with advanced PGP security in Quatrix.

To share encrypted files you should select the PGP encrypt files check box on the Optional Settings section while sharing files.
