This article explains how merchant's can use the Gnu Privacy Guard (GnuPG) to encrypt sales data.

Feefo supports a sales file encrypted with GnuPG, the suite of free and open source cryptography solutions. The file needs to be encrypted with the Feefo public key prior to uploading to our FTP server. Ensure the file extension is set to .gpg whereupon it will be automatically decrypted and processed.

GnuPG can be downloaded from the GnuPG website. Refer to the documentation supplied with GnuPG on how to encrypt the file successfully.
Feefo accepts file transfers with GnuPG (Gnu Privacy Guard) encryption.
GnuPG encryption relies on a 2-part key, one for encryption and another for decryption.
To encrypt a file you will need to use Feefo's public key which can be found below:

When the encrypted file reaches Feefo it will be decrypted by the private key that's held securely in the Feefo application.

The name of any GnuPG (GNU Privacy Guard) encrypted files themselves are not important however the file extension must follow a strict format.
Any GnuPG encrypted file must include the correct filetype extension (e.g. .txt, .csv, .xml) and then followed by .gpg. For example, exampleupload.csv.gpg.
This naming convention means that Feefo will know what format the file is after it has been decrypted. Failure to include the base file extension will cause the file to sit on our servers unprocessed once it has been decrypted.
