When I try to convert the private key I pulled from CloudHSM with PuttyGen for use with Putty, I get an "unrecognized private key format" error. Anyone else running into this?
I had same problem
If you have open ssl try: openssl rsa -in inputkeyfile -out newkey.pem
Then use puttygen to conver to ppk
this worked for me.
Same problem. I used Francesco.ricci’s suggestion. We were already using openssl on our EC2 instances so I converted the private key to a new .pem file which Puttygen successfully turned into a .ppk file. command: openssl rsa -in
