While Cerberus does cannot PGP encrypt files, you can utilize some of Cerberus' features to utilize PGP encryption.
Automatically decrypt files received and encrypted by PGP automatically (e.g.: Files are dropped by the customer in a share).
You could create a file transfer event along with command line client like Open PGP to decrypt a file when someone uploads a file.
See our documentation on creating events.
Options to use Cerberus with PGP
Cerberus FTP Server does not have a built-in PGP encryption function, a third party application would need to be used prior to the transfer to encrypt the actual file. Cerberus does not endorse any particular third party software to do the encryption. Cerberus would transfer the file only. Cerberus would also not have anything to do with decrypting the file once it reaches its destination.
Generating/configuring a PGP key within the Cerberus FTP software
Cerberus does not have the option to create the keys within the software. You will need a third party tool such as PGP Key Generator.
