JWT configuration

In KDone login works with JWT tokens, so it is necessary to configure JWT login before configure models and users.
JWT configuration is done passing JWTConfig to startKDone function.

startKDone(
        port = 23146,
        mongoURL = "mongodb://localhost:27017/games",
        jwtConfig = JWTConfig("<secret>")) {

}

JWTConfig needs at least the secret string to sign JWT token. Other parameters are

• issuer string, by default set to “kdone.com”
• validityInMs represents JWT tokens validity, by default set to null, which means that JWT tokens never expire
• algorithm used to generate JWT tokens, by default set to HMAC512
