The current OpenSSH defaults (7.5+) are reasonable, and do not include the insecure rc4 ciphe= r: chacha20-poly1305@openssh.com, aes128-ctr,aes192-ctr,aes256-ctr, aes128-gcm@openssh.com,aes256-gcm@openssh.com, aes128-cbc,aes192-cbc,aes256-cbc I think I recall there being a reason for a specific list of ciphers on G= CE at the time, but I do not recall what it was, and cannot find any current GCE documentation of such a list. So, just revert the explicit configuration and use sane openssh defaults.
