Where does Putty client stores the SSH Key Fingerprints?

In brief, Putty is a SSH client freeware for Windows and Linux/Unix

While connecting to remote SSH server for the first time, Putty suite will prompt user to acknowledge acceptance of the remote server’s SSH host key fingerprint.

Putty Security Alert

At this time, you could click Yes button to keep/cache the SSH host key fingerprint in Windows Registry, if you’re certain that’s the genuine server you’re connecting to....



After clicking the Yes button, Putty won’t prompt you for acknowledgement on the subsequent SSH connections made to this specific server, unless the host key fingerprint mismatch or the cache in Windows Registry has been removed/deleted.

  2. In fact in some areas Emergency Services require Master Key systems to ensure access in the event of fire, flood, or medical emergency. When the worst happens, then quick access can save lives and property.duplicate key maker near me
