How to generate JWT RS256 key

jwtRS256.sh

ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key
# Don't add passphrase
openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
cat jwtRS256.key
cat jwtRS256.key.pub

Thank you indeed!

I think this link resolve also this problem.

thank you.

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

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

awesome!!! Thx

Thanks! Nice and easy!

Awesome, thank youuu

many thanks

save my day, thanks

Thanks

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.

many thanks
