If you are testing this by creating your own user, create the user first as well as generate SSH/SSH2 based key pair. Create a user for your client company and install the SSH/SSH2 based public key provided by your client.You can also set the software to only perform SSH or SSH2 key based authentication. Make sure that there is no firewall blocking this port. Configure the server so that it accepts SFTP client requests.Make sure that server software does support the SFTP and with preferable SSH2 keys. I am deliberately avoiding the name of any product. First download a server software, most of them are available at a very low cost.We are not going in the detail on how does the key pair based data encryption works. Primarily, PGP provides the encryption/decryption (privacy) of the contents as well as Signing (authentication of the sender and integrity of the contents). PGP is an abbreviation of Pretty Good Privacy and it comprised X.509 key pair based security techniques. Importantly, SFTP works with SSH or SSH2 key pairs whereas FTPS uses the X.509 key pairs that are used in X.509 certificates commonly known as digital certs. FTPS is FTP protocol using secure transfers on SSL. Setting up SFTP with PGP support is very simple provided the fundamentals are clear.įirst of all SFTP is file transfer on Secure Shell (SSH), therefore, it is different from FTPS.
