1SSH-KEYSIGN(8) OpenBSD System Manager's Manual SSH-KEYSIGN(8) 2 3NAME 4 ssh-keysign - ssh helper program for host-based authentication 5 6SYNOPSIS 7 ssh-keysign 8 9DESCRIPTION 10 ssh-keysign is used by ssh(1) to access the local host keys and generate 11 the digital signature required during host-based authentication with SSH 12 protocol version 2. 13 14 ssh-keysign is disabled by default and can only be enabled in the global 15 client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign 16 to ``yes''. 17 18 ssh-keysign is not intended to be invoked by the user, but from ssh(1).

They should be owned by root, 29 readable only by root, and not accessible to others. Since they 30 are readable only by root, ssh-keysign must be set-uid root if 31 host-based authentication is used. 32
