For
all those of you who have been trying to clear Putty’s cache of host
fingerprints (Windows) for development or testing, here is the
answer:
1. Open the registry
(regedit)
2. Go to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys
There you
should see Putty’s cache of host keys.
The ‘name’ column tells you which key
is for which server.
For
example, it will have the format of
@: [rsa2@22:172.16.117.159]
3.
Delete the rows that you need and presto!
That’s all there is to
it.
