ssh-keysign is used by ssh(1) to access the local host keys and gener‐
ate the digital signature required during host-based authentication.
ssh-keysign is disabled by default and can only be enabled in the
global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to “yes”.
ssh-keysign is not intended to be invoked by the user, but from ssh(1).
See ssh(1) and sshd(8) for more information about host-based authenti‐
Controls whether ssh-keysign is enabled.
These files contain the private parts of the host keys used to
generate the digital signature. They should be owned by root,
readable only by root, and not accessible to others. Since
they are readable only by root, ssh-keysign must be set-uid
root if host-based authentication is used.
If these files exist they are assumed to contain public cer‐
tificate information corresponding with the private keys above.
