I wanted to connect to my Unix server using SSH keys. For that I had converted my id_rsa
file from ./ssh
directory to a ppk file using PuTTYgen, but after loading my .ppk
key I get this warning:
PuTTY key format too new
If I use my default id_rsa
file, then I get error:
OpenSSH SSH-2 private key (old PEM format)
Either way I am getting stuck. Can anyone please help me?

If you have a key in the new PPK version 3 format, you can use PuTTYgen to export it to the old PPK version 2 format.
I don't know what Operating System you're using PuTTYgen/PuTTY on, but if it's Microsoft Windows you can set PPK Version 2 by default for PuTTYgen selecting in the app menu:
Key->Parameters for saving key files...->PPK file version: 2.
