How do I get the public key of a pem file?

January 15, 2023 by Tarik

Copy the public key to clipboard.

Linux

ssh-keygen -f private.pem -y | xclip

MacOS

ssh-keygen -f private.pem -y | pbcopy

Save to file

ssh-keygen -f private.pem -y > public.pub

Note that if your permissions are vague on the .pem file, then ssh-keygen will generate an empty .pub file.

You can usually fix this with:

chmod 400 private.pem
