SSH Public Key Authentication

[Pedro Cirne]

Hi,

Is there a way to make a private key valid only if used from a certain host?

In other words, I want to setup an authentication method in a way that the my private key only works if I'm using it to login a server from my PC. So if I (or someone else) copies my private key to another PC it won't work to login on the server.

There is a key generator for Windows that should let you generate and distribute a private key that will only work for you.

Yes, use from="hostname" in your ~/.ssh/authorized_keys file.


The from entry will be on the same line in front of the public key.

from="ip_address" ssh-dss ...

Hope this helps,
