jwt-demo

A simple demo about JWT token with Go.

go jws - PEM

• openssl req -newkey rsa:4096 -x509 -sha512 -days 365 -nodes -out certificate.pem -keyout privatekey.pem => this generates the certificate together with the private key
• openssl x509 -noout -in certificate.pem -text => used to see in a text-form the content of the certificate
• openssl x509 -pubkey -noout -in certificate.pem -out publicKey.pem => to extract the public key from the certificate
