Alright so after about a week of working on this I THINK it's done (for now but more is planned). It may be a bit sloppy but it works. You are all welcome to comment, suggest or even help clean this beast up a bit. Welcome to my login system! Let me take a minute to explain it's features.
LOGIN FEATURES
PLANNED FEATURES
PASTEBIN
LOGIN FEATURES
- Matches username and password to allow access to a program that requires credentials. (username is a file in users/[username] and password is a line of text within said file)
- Ignores blank entries for both username and password and after several failed attempts will kick you back to the main menu.
- Will ignore unknown usernames.
- Will lock down an account after three failed attempts to log in with an invalid password. (locked accounts are moved from users folder to pending folder and renamed to a random number for safe keeping. Will also check to ensure the random file name is not already in use)
- Admin override feature allows the system owner to enter the system shell without risk of major security breaches by utilizing a random password algorithm to generate new passwords upon each override request. (Current algorithm is (rnd + 11) * 83 where rnd = a random number generated by the system and displayed as an override code. Admin override login name is currently adminovrride)
- Reads the user account and applies an access level based on what the Admin has set for that user. (Currently only two access levels, admin and user, with more able to be added)
- Allows user to create an account by providing a username and password. The system then puts the information in a randomly generated file in the pending folder for safe keeping and admin approval at a later time. (Will check to ensure random file name is not already in use)
- Ignores blank entries for both username and password and after several failed attempts will kick you back to the main menu.
- Will ignore usernames already in use.
- Will disallow the creation of an account using the same login of the admin override feature.
- Matches password and confirm password to ensure the user selected a proper password for themselves.
- Ctrl-T is disallowed.
- Max input length is currently set to 12 but can be changed.
- Easy to modify to suit your needs.
- Self-sustained program in itself to allow easy integration to your system and it's other programs.
- Basic design to allow users of both basic and advanced computers to use this login system.
Two directories need to be pre-made prior to running. These directories are [users] and [pending] without the brackets and must be placed in the root of the system.
PLANNED FEATURES
Ability to determine whether the user is an admin or user. (Possibly other access levels as well)- Integration into an overall OS where the system boots and does a system check. (memory, file structure etc.) If the check fails it will initiate a system restore sequence from disk to restore the system to it's previous state including any back-up files saved.
Checks to see if the "pending" and the "users" directory exists. If not the program will create them.
