The problem
I was on AWS and needed to select SSH Key pair.
It has been a while that I needed to create one that might require SSH Key pair.
So to be sure I got the correct key, I needed to compare fingerprint listed on Key Pair list.
I do have pem key with name contain aws so I want to generate finger print for that key.
How to solve it
openssl pkcs8 -in path/to/private_key_file -nocrypt -topk8 -outform DER | openssl sha1 -c
or use AWS tool
sudo apt install ec2-api-tools
ec2-fingerprint-key path/to/private_key_file
That’s it!
Cheers!
