Editing Security


This page describes the current status of security in AAGRINDER.

== Authentication ==
In AAGRINDER, users authenticate with their passwords.
The password is chosen when the account is created and needs to be at least 1 character long.
The password may contain any characters.

The password is transmitted to the server in plaintext. However, if you are using a https connection,
this transmission will be encrypted.

On the server, the password is hashed and salted using [https://www.npmjs.com/package/bcryptjs bcryptjs] and then saved in a [[wikipedia:MySQL|MySQL]] database. The relevant part of the code can be found [https://gitlab.com/MRAAGH/aagrinder/blob/master/server/User.js#L120 here]. The plaintext password does not persist in memory on neither the client or the server.

Users can change their passwords by using the '''/passwd''' [[client command list|client command]] in-game. It is also possible to change the password with a direct [[AAGRINDER REST api|api call]]. In both cases, the current password is required in order to set a new one. If you lost your current password, you should contact the server administrator.

There is currently no functionality for changing an account's password. If you want your password changed, you should contact the server administrator to reset your account (progress in the game will not be lost).

There is an alternative mode called [[Running in insecure mode|insecure mode]] which can be enabled by toggling a server setting. We call it "insecure" to decrease the confusion between the similar words "authentication" and "authorization". If enabled, passwords will be completely ignored at login, and the client will not prompt the user for password.

== Authorization ==
Additional privileges may be granted to specific users at login.

Among the in-game commands that get executed on the server, some are in the group of ''admin commands'', which prevents users from accessing these commands unless they have the ''admin'' role. The names of users with the admin role are specified in the file ''admins.txt'' in the server directory. This file needs to be edited manually.

Older versions of AAGRINDER have a ''/sudo'' command, which allows a user to run a command as any other user, and requires additional privileges (an entry in ''sudo.txt''). The ''/sudo'' command [https://gitlab.com/MRAAGH/aagrinder/-/commit/e89398ba2f59e5f84a601d87d5fe7dd8296612b1 was removed] on September 4, 2022.
