This week I needed to verify an SSH private key password as I wasn’t sure if it was the correct password.
After some Google research, I found this blog post with the exact solution to my question: How to verify your SSH private key password
ssh-keygen -y -f /path/to/ssh_key
-y: parameter will help us to verify the password key, checking the private key and printing the public key to the stdout.
-f: enables us to select the ssh key we want to verify.
