How can I test my ssh-keys locally without a server

Question

I want to test my keys in ~/.ssh. I do not have sshd running (Git-Bash@Windows does not provide it). I'd like to test if I still remember the passphrase for my keys.

I found these answers [1], [2], but they do not work for me.

Is there an easy way to verify my ssh keys without an ssh server?

Answer 1

This should work:

ssh-keygen -y

Or to avoid filename prompt question:

ssh-keygen -y -f key_file
