I use Vandyke’s SecureCRT to access my linux machines. Due to the recent increase in the number of attempts to break-in to my systems via SSH, I decided it was high time I switched to using public/private key authentication instead of simply password.

I had devil of time figuring out how to get the public key generated by SecureCRT into OpenSSH’s authorized_keys2 file.

After digging through the SecureCRT help file for a bit I finally found the command (it was pretty obvious, had I read further).

cd .ssh
ssh-keygen -X -f Identity.pub >> authorized_keys2

Now I just have to figure out a way to keep my public keys with me whenever I might have need to access my systems without a system I work on normally.
