Server based password door lock

[RokutheBasiliskTamer 2]

This is a simple door opening script that requires a password to be entered. That being said it took me a ridiculously long time to work out all the bugs. It works by taking an input from one computer and sending it to another to check if the password is correct. This makes it much harder to simply look at the file to check what the password is.  It also now has the ability to automatically encrypt your password if you have a T1 data card along with the server asking you to input a password on the first run. These ideas came from the user RandomRedMage

Requirements:

• At least 2 computers with basic parts
• 2 Network cards or Wireless Network cards
• Redstone T1 card
• Data card T1 (optional)

The pastebin id for the server version is 8Y2y9xH3 

The pastebin id for the client version is F5P5V05P 

Source code for both here

Currently it needs to be placed into /home/bin and named door.lua to work but editing the 4 spots where os.execute is called will let you place it wherever with any name

Also you need to enter the password twice the first time it is booted in order to have both computers recognize each other this can be circumvented via hard coding the address of the modem of each system into the other or adding a file into each /home/bin called MAC.psd with the modem address of the other.

It is currently set up for only one computer but it could easily made to work for multiple by making the address var into a table and having a loop check thru them though that may slowdown the process.

Really simple, but a great start. I would at the minimum change this so that the server program when booted for the first time, asks for the password you want, encrypts it. and stores the encrypted password in a file.

Thanks for the input I implemented both of those ideas

Why not set it up using an coroutine to check for any computers listed in the MAC file once every so-and-so cycles?

what you also and do is add multi user register as well as access limiting like level 1 to level 3 door access 

and also user logging eg. (door name, door access level, player name)

 

if i may all take a look and see what i can do to add this, but its still a cool program thanks for sharing

That's what hashes are for.
