This entire panel is only relevant to SSH protocol version 2 none of these settings affect SSH-1 at all. If you don’t understand what any of this means, it’s safe to leave these settings alone.

Key exchange is a cryptographically intensive process if either the client or the server is a relatively slow machine, the slower methods may take several tens of seconds to complete. It is therefore very important for the security of the connection that the key exchange is secure. Key exchange occurs at the start of an SSH connection (and occasionally thereafter) it establishes a shared secret that is used as the basis for all of SSH’s security features.
