I am currently trying to setup an authenticated scan but when entering my private key - I am getting a message saying invalid or empty private key. I have tried generating a new private key from other articles I have read but nothing works. I need to be able to use a key based on my original puttygen generated private key as my public key is on all of our servers. I have tried conversions using multiple methods - generating openssh keys, changing the generation versions and other methods) but nothing works. I changed the type to ed25519 as mentioned in another article but this does not work either.
Do you have a standard method that works - to regenerate a private key from an existing private key - that will work in the Greenbone Openvas system. Nothing I have read so far has worked so I really need some help here.
