Remove RSA Keys from Authorized List

I am testing an application and want to remove the RSA-keys that I have previously accepted.

How do I remove these keys?

Thanks for any assistance

If you want to remove all cached SSH server host keys:

If you need to remove some only, you need to do this manually by removing respective entries in SshHostKeys section of your configuration:

Thank you.

That is what I needed
