OpenSSH helper for host-based
ssh-keysign is used by
ssh(1) to access the local host keys and generate 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 authentication.
- Controls whether
- 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-keysignmust 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 above.
