types you want to support in your sshd_config. We use the ssh_version fact to determine the default hostkey types. Only enable rsa and ed25519 for ssh versions greater or equal to 6.5, otherwise enable rsa and dsa. Some distributions, such as debian, also enable ecdsa as a hostkey type, but this is a known bad NIST curve, so we do not enable that by default (thus deviating from the stock sshd config)
