create json web token

// 12시간
val expiration = System.currentTimeMillis() + 12 * (60 * 60 * 1000)
val base64EncodedSecretKey = "your_secretKey_abcdefghijklmn=="

val builder = Jwts.builder()
    .signWith(SignatureAlgorithm.forName("HS256"), base64EncodedSecretKey)
    .setIssuedAt(Date())
    .setExpiration(Date(expiration))
    .claim("userId", userId)
    .claim("name", userName)
    .claim("gender", gender)
    .claim("age", age)
    .claim("userScore", userScore)

val jwt = builder.compact()
tvJwt.text = jwt
