Hello

When I look in my file /etc/ssh/ default key rsa , for activated the key Rsa I just changed shhd_conf in removing the argument #

I do not understand your previous posting. Are you asking a question about public key use?

If so:

Server keys for SSH (all /etc/ssh/*key* files) are created automatically the very first time you boot OpenBSD after installation. These are used to authenticate the SSH server with SSH clients.

Client keys are created with ssh-keygen(1).

Here is a simple "how to" to switch from password authentication to public key authentication -- I hope it is clear to you once you run it through a translation into French:

Overview:

1. You disable password authentication. Public key encryption is enabled by default.
2. A user generates her own pair of keys -- one is private, the other is public. She may do this on her own, remote system.
3. The user sends her public key to you, if necessary.
4. You install the public key in her account, if necessary, or she does it herself, if she is local.

How to:

1. Edit /etc/ssh/sshd_config:
   Change "#PasswordAuthentication yes" to "PasswordAuthentication no"
2. The user generates her key. If she's using OpenSSH, she uses ssh-keygen:
   $ ssh-keygen -t rsa -N "the pass phrase she will use with her private key"
3. If she is remote, she sends you only the public key. (She keeps the private key on her remote system.) Any method may be used to transfer the public key to your system, including e-mail, web page, or posting on a forum. This half of the pair is safe to submit via any method. The private key is not transmitted.
4. She, or you, place the public key into her .ssh directory:
   $ cd /path/to/her/home/directory
   $ cp /path/to/her/public/key/file .ssh/authorized_keys

She can now log on via public key authentication. Neither of you need ever send passwords back and forth.
