Thanks! What if I need to use the private key associated to a Metamask wallet to sign? Can I do it by manipulating the key or do I need another type of key altogether?

Thanks!
BTW @ygotthilf you can add -N '' to ssh keygen and it will not even ask for passphrase

Now, it doesn't work because newer version of ssh-keygen no longer uses PEM format as default key format. It have changed to RFC4716 for default key format. Thus, I have to set PEM format explicitly :

ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key

This will work 👍

In case anyone is getting an error from openssl, try this.
