GPG Decryption

---

Files.com site administrators can enable GPG decryption on a per-folder basis.

Enabling GPG decryption for a particular folder also means that files uploaded to any subfolders within that folder will be automatically decrypted unless you explicitly disable the folder setting on a subfolder.

GPG decryption requires a GPG/PGP Private key. You can generate a GPG/PGP key pair using the GPG Key Manager or by using the appropriate GPG software for your operating system. See our steps for Windows, MacOS and Linux. You can also choose to securely generate the key pair in your browser while setting up GPG decryption.

You can use a different private key for each folder you enable decryption on.

Files.com will attempt to decrypt every file uploaded to this folder or its subfolders using the selected private key. If a file cannot be decrypted then it will remain in its original form. Only files that were encrypted with the matching Public Key will be decrypted. If the Public Key has expired then decryption cannot be performed.

To avoid non-encrypted files being uploaded into a decryption folder, you can use the Folder Setting for Limit uploaded files to certain extensions so that only PGP or GPG files will be allowed.

When enabling GPG decryption on a folder, files that were uploaded to the folder prior to enabling the setting will not be automatically decrypted. You can re-upload those files to have GPG decryption applied to them.
