SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
ssh-keysign — ssh helper program for host-based authentication
ssh-keysign
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‐
cation.
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_ed25519_key
/etc/ssh/ssh_host_rsa_key
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.
/etc/ssh/ssh_host_dsa_key-cert.pub
/etc/ssh/ssh_host_ecdsa_key-cert.pub
/etc/ssh/ssh_host_ed25519_key-cert.pub
/etc/ssh/ssh_host_rsa_key-cert.pub
If these files exist they are assumed to contain public cer‐
tificate information corresponding with the private keys above.
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)
ssh-keysign first appeared in OpenBSD 3.2.
