How to use

import com.ducreyna.jwt;

String key = "secret";

try {
	// Encode a JWT with default algorithm
	HashMap<String, Object> payload = new HashMap<String, Object>();
	payload.put("name", "ducreyna");
	payload.put("admin", true);
	payload.put("state", new HashMap<String, Object>());

	String token = Jwt.encode(payload, key);


	// Encode a JWT with an algorithm of your choice
	HashMap<String, Object> payload = new HashMap<String, Object>();
	payload.put("name", "ducreyna");

	String token = Jwt.encode(payload, key, Algorithm.HS512);


	// Decode a JWT with signature verification
	Map<String, Object> decoded = Jwt.decode(token, key, true);
}
catch(Exception e) {}
