With file.ppk file to connect to server using ssh. As I am a Ubuntu user, I need a key that supports the terminal command. So want to convert to .pem file.

I am sharing the steps to convert PPK to Pem format on the Linux terminal using a putty gen tool.

  • Step A – First of all, install the putty tools on your Linux system using below command.
    sudo apt-get install putty-tools
  • Step B – Now, convert the ppk file to pem file using puttygen command line tool.
    puttygen server1.ppk -O private-openssh -o server1.pem
  • Step C – Change the .pem file permissions. Set the read-only permissions to the owner of the file, remove any permission to group and other. Otherwise ssh will refuse this key for use.
    chmod 400 server1.pem
  • Step D – Finally, connect to your remote Linux server with ssh using this pem key.
    ssh -i server1.pem ubuntu@
