How to use Putty private key with git
  1. Convert Putty private key to OpenSSH private key.
  • Linux: with your package manager, install PuTTY (or the more minimal PuTTY-tools):
    • Ubuntu sudo apt-get install putty-tools
    • Debian-like apt-get install putty-tools
  1. Generate the private key: puttygen id_dsa.ppk -O private-openssh -o id_dsa
  2. Generate the public key: puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub
  3. Copy id_dsa (600) and id_dsa.pub (644) to ~/.ssh folder
  4. In ~/.ssh/config, add:
