Which means that your local Personal computer will not recognize the distant host. This will transpire the first time you connect to a brand new host. Kind Certainly and push ENTER to carry on.
The general public key is often shared freely with no compromise in your stability. It is actually not possible to ascertain just what the personal key is from an evaluation of the general public essential. The private key can encrypt messages that only the non-public important can decrypt.
