"Error Message Invalid Key" WebStorm when connecting to Google Compute Engine instance as a remote server

Question

When I am trying to add .ppk file in WebStorm for getting remote server access for my Compute Engine instance I am getting an error in WebStorm:

google_compute_engine.ppk is corrupt or has unknown format. Only SSH2 Keys in OpenSSH format (DSA, RSA, ECDSA) or PUTTY private Key *.ppk are supported. Error Message Invalid Key : [xxxxxxxx]

Answer 1

I went through this post how-to-convert-ssh-keypairs-generated-using-puttygenwindows-into-key-pairs-use and then I did these steps.

1. open puttygen

2. Go to file and then load private key

3. Generate public/private key value pair click on generate.

Now use this newly generated key inside Webstorm.

Answer 2

Invalid

-----BEGIN OPENSSH PRIVATE KEY-----

Correct

-----BEGIN RSA PRIVATE KEY-----

Step to fix

Remove old files

rm -rf ~/.ssh/*

Create new File (-m pem)

ssh-keygen -t rsa -b 2048 -m pem -f ~/.ssh/google_compute_engine -C username
