| Class | Net::SSH::HostKeyMismatch | 
| In: | lib/net/ssh/errors.rb | 
| Parent: | Exception | 
Raised when the cached key for a particular host does not match the key given by the host, which can be indicative of a man-in-the-middle attack. When rescuing this exception, you can inspect the key fingerprint and, if you want to proceed anyway, simply call the remember_host! method on the exception, and then retry.
Returns the fingerprint of the key for the host, which either was not found or did not match.
