I use two applications based on SSH: SmarTTY and an FTP client (Ipswitch WS_FTP). The latter provides a command to generate a key pair whose public half I export and upload to my Linux servers.
However, I cannot find an equivalent mechanism for SmarTTY. What is more puzzling is that I somehow managed to establish the certificates in client and server (see screenshot), but I cannot replicate it.
What is the meaning of “Set up public key authentication and don’t ask for password again”? Is this something that can be done unilaterally, i.e. dealing with SmarTTY alone and letting it somehow (automagically) transfer the public key to my server?
