  • on https://jwt.io/#libraries-io you can find a lot of libs, and usually you get examples for their usage in the docs or homepage. – jps Jul 26 '19 at 14:30

You can create it for example with Java JWT: JSON Web Token for Java and Android

Example:

import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import io.jsonwebtoken.security.Keys;
import java.security.Key;

// We need a signing key, so we'll create one just for this example. Usually
// the key would be read from your application configuration instead.
Key key = Keys.secretKeyFor(SignatureAlgorithm.HS256);

String jws = Jwts.builder().setSubject("Joe").signWith(key).compact();
