Certification Authentication

SSH Key Authentication

If you already have a private key from FTP server administrator, then you can simply enable "Certification Authentication" on "Profile wizard → FTP Server" and specify your private key file and password (if specified).

SSH Key Generation

If you don't have one, you can generate your own key pair and send the public key to FTP server administrator. You can use any standard tool to generate public and private keys, such as PuTTYgen.

Key Export

After it's generated, please export the private key file in OpenSSH format, that's what FTP Synchronizer supported.
