ssh-keysign -- ssh helper program for host-based authentication
ssh-keysign is used by ssh(1) to access the local host keys and generate
the digital signature required during host-based authentication with SSH
protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global
client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign
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
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
certificate information corresponding with the private keys
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)
ssh-keysign first appeared in OpenBSD 3.2.
