SSH: keys and structure

[Wim Barthier_2]

Hello,
I am running OpenVMS 7.3-2 with TCPIP 5.4-155

I need to set up ssh between OpenVMS and MainFrame as well as Sun Solaris.

1) Is there anyone who can tell me how ssh keys should be formatted?

2) Is my perception correct if I only need to:
- config with publickey authorization
- start SSH daemon
- TCPIP$SSH_HOME:[SSH2.HOSTKEYS]key_22_hostname.pub put the public host keys of the machines to which I want to connect with
- [username.SSH2]AUTHORIZATION. the index of the private keys of the users who will connect
- [username.SSH2]KEY_22_username_hostname.pub all the clients public keys

May be my notes can help you.

The easiest way to see that is to make a set
of keys (SSH_KEYGEN) on the VMS system. (You
don't need to use them, of course.) And the
file format on Solaris does seem to differ.
On Solaris, "ssh-keygen -X" (or -i,
depending) will convert _to_ the Solaris
format. I don't know if there's a non-manual
way to go in the other direction. (I started
with VMS-generated keys. Tru64 likes them
with no changes.)

I believe that these are created
automatically as needed when the first
connection attempt is made.

Otherwise, that sounds about right.
