Is there a way in WinSCP to configure a known_hosts file with key fingerprints so as to not be queried by WinSCP when you want to connect?

WinSCP does not use known_hosts file. Like PuTTY, it stores known host keys into Windows registry (or optionally an INI file)

[HKEY_CURRENT_USER\SOFTWARE\Martin Prikryl\WinSCP 2\SshHostKeys]

The format of the keys is different to that of known_hosts.

If you have the host key cached on another machine, you can copy it over to the new machine.

But you can import the host keys from the known_hosts file.

Another way is to have WinSCP save new site with a known fingerprint of the host key, like:

winscp.exe sftp://username;[email protected]/;save
