Unable to load private key file .ppk (file format error)












1














I generated an Ed25519 key pair with puttygen, and saved the private key on my computer.



When I try to authenticate with it, I get



Unable to load private key file "my_private_key.ppk" (file format error)


I checked that it really is a private key file, the file format should be correct as it it generated by puttygen.



Any ideas how to fix it ?

          The version of Putty I used was too old, it did not support ed25519 at the time.
          With the latest version (0.70), the error is gone.
