About OpenPGP

OpenPGP is a key-based encryption method used to encrypt files so that only their intended recipient can receive and decrypt them. OpenPGP is used widely to secure e-mail communication, but its technology can also be applied to FTP.

OpenPGP works by using two cryptographic keys to secure files. A Public Key is used to encrypt the file so that only its corresponding Private Key can decrypt it. For more information, see OpenPGP.

Note: Unlike SSL and SSH, OpenPGP is not a type of connection, but a method of encrypting a file prior to uploading it. As such, OpenPGP Mode can be used in conjunction with standard FTP, SSL or SSH connections.
