Creating ssh keys for Windows

SSH keys allow for improved access to Research Computing clusters by bypassing the need for 2Factor authentication. Adding your public key to the cluster will allow tools such as Filezilla, ssh, putty and others to more quickly and easily connect. 

  1. To generate a key pair use PuTTY’s generation tool called “PuTTYgen”
  2. Once Launched make sure RSA is selected in the bottom left, then click “Generate”
  3. Move your mouse around the blank area near the progress bar to add randomness to the key
  4. Enter a keyphrase and confirm it (not necessary but recommended)
  5. Click “Save private key” and save it
  6. Click “Save public key”
  7. Copy the whole Public key on the top of the generator
  8. Open
  9. Login
  10. Click the tab “Clusters” and select “Koko 3 Shell Access”
