Changelog

Spoiler

4.8.1
INITIAL RELEASE

4.8.2
- Added keypad censorship
- Changed colors around for greater visibility
- Customizable vertical position

4.8.3
- Fixed the bug allowing you to have 0's in your pin despite the keypad lacking a "0" key.

4.8.4
- Added persistent data. To edit config, terminate program and type "edit pin/data". I will try to make this an easier process eventually.

4.8.5
-Made the configuration easier and added an option to change the PIN

Upcoming

• Config file (persistent data , very easy to implement, just very late at night right now and i'm going to bed.) (sort of done)
• Bug Fixes that I already spotted (Report any bugs you notice please :D/> )
• Automatic monitor scaling
• easier customization (better setup wizard)
• more options
• Zero.

Known Bugs

• If anyone can get the hash they can get the pin because of readily available rainbow tables

Video coming soon if the feedback is positive.

Awesome! Im going to have this in my base! ;)/>
Easy to use and edit!
Good Work! =D

5/5 Stars! =D

I like it when new members make new things. I really like this. Kudos to you ^_^/>

Thanks for the feedback guys. I've been reading the forums for a while and into CC since I discovered it in Tekkit. CC is my first programming experience.

You should add the 0

Oh, is it possible to hide the numbers on the monitor with a * ?

I havn't looked at the program at all yet so I don't know what you are doing but, you could make it so every time the event passes from a key being pressed on the monitor it prints a * instead of printing the letter.

Yeah. Thats what I want

local input = read("*")

This can be used with any character/letter/number

Mackan90096, on 09 April 2013 - 06:07 AM said:

I don't intend to add a '0' key. I intend to make sure you don't make a pin containing a 0.

I have added this feature and pushed the first update
simply run the following commands

delete startup
pastebin get SDvHNe61 startup

and then restart your computer again (Ctrl+R)

This doesn't make sense in the context of how I render the page. I don't use read, the program is based on monitor touch events.

Oh, I didn't read that carefully. Forget the read("*") code I posted. You would need to do something with tables, which I don't really feel like explaining at the current moment. However, if you already use tables to render your screen, then this would be easier for me to explain/make a script.

I have already added the feature in question and have added a new configuration variable at the top of the program to toggle it

Wow, you're new and smart :)/> I like you already ^_^/>

Good job, i'm really liking this.

This thing is epic. Thanks!

Instead of removing the 0 bug, why not add a "0" button?

Mind if I make something like this? It's a keyboard program for an adventure map I'm working on.

what does the "COR" button on the monitor do?

Can't remember, but I can remember the colors of the bottom buttons:
Orange: Backspace
Red: Clear
Green: Confirm

And also, this is how to make editing easier:

Spoiler

Make a new line of text on the terminal:
'E - Edit config' and make this code if E is pressed:

m.clear()
m.setCursorPos(1,1)
shell.run("edit pin/data")

Because shell.run(<program>, [arguments]) runs that program.
<> = required
[] = optional

Edit: I found a bug:
The new wired modems don't work with this program.

Here is my verison of the same thing, except I opted to make it small so it can be put out of the way. Its only one monitor, but it works pretty well:

[media]http://youtu.be/gcuINzwYdV0[/media]

Also in that video is my sensor door lock, but that can be for another thread. Here is the code I used for the keypad. I have had it working for about a week now with no problems, so if anyone finds any bugs, please let me know. Also, any pointers on ways I can optimize the code would be nice.

At the moment, the password is hard coded and I have plans to change that. Also, I'm planning on adding a bit more feedback on the gui, making it flass green with "access granted" and red with "access denied"

Let me know what you think.

Hello,

This program is great. the problem is that the hitbox of the buttons is pretty messed up, especially for the first row (1,2,3). Pressing a number sometimes even gives the wrong number. Maybe it's a scale issue? It's not usable in the current state.

Also, putting censor to false doesn't work.

Edit: In fact, none of the changeable options I tried at the beginning work.

how to edit pin?

That was a giant, 5 month bump.

how to edit pin?

Try editing the program on line 135 and see if that works.

Unfortunately, SHA-256 is not suitable for 1-5 digits pins, and a simple lookup of the hash on Google will yield the pin,
since there are rainbow tables of 00000 through 99999 on the net.
A way to mitigate this would be to implement a salt, if you need help with that, I can give you a hand, just PM me :)/>

Edit: Sorry for the bump, but I felt that it was necessary to bring this up.

how did you hack into a computer blocked and protected from access the only way to access it was to break a protected block?

That's not the point of the post, but anyway, you can do that by breaking a protected block and clicking the computer before that protected block respawns.

I have released an update for this program. Pease see the change logs in the first post.

It stands for "correction" and its basically a backspace.

Let me know what you think.

I think your layout looks really nice. One issue that I'm having with my program is that in order to use it at optimal size (scale 0.5) you need to stack two monitors or you lose the frame.

Not sure what was going on with the hitboxes. Should only accept hits on the number itself or either of the blank spaces beside the number. Haven't had a chance to test this yet. almost all of the options were broken with the last update. I have fixed it somewhat. anything that isn't in the main config should update with 'edit pin/data'

ah yeah that makes sense. But to be fair this is more for show, even with protected blocks and anything else you can think of short of Adventure Mode, I am sure there are 1000 ways to break into this. if you can access the computer you could just Ctrl+T and open the lua console and write 'for _,v in pairs( rs.getSides() ) do rs.setOutput( v , true )'

alright so i need to know. is there a way to use a modem to link it to a monitor for far distances (better security basically)

Hello! Thank you a lot for this program!

I've modified it as you can see in this video:
https://www.youtube....eature=youtu.be

I've changed it to actually do a "secure" PIN authentication against a remote (wired) 2nd computer.
It requests a salted 1-time hash from the pin server and then sends the password hashed against that to the remote side which can then validate it or not.
This simultaneously solves the rainbow table attack, and makes it so the terminal granting/denying access can be placed remote of the terminal for entering the codes.
It also makes it so you can have multiple PIN Terminals but only a single authenticator controlling access, as seen in my video.
I have plans to make the Pin Server program keep logs and display logs to monitors, and to just generally make this nicer.. For now it's too rough to be considered releaseable for other people..
But here's the code if you want to see!

My modified version of your script: http://pastebin.com/1Qqk7c6D
My PIN Server script to run on the other terminal: http://pastebin.com/JHV9wG73

Thank you for your keypad script it's very well written!

Thank you, I have been looking everywhere for something like this! I think this will be epic for my base! :D/>

If you have the numbers visible then it makes the lock a bit unsecure.

This makes me pretty happy. I read through your additional code and I enjoy it. It's still hackable though ;)/> . Your plans for the base control system are ambitious and I would recommend scrapping most of what I've done in favour of something that can be more modularized and expanded upon. In my code I have hard coded a lot of things that should not be hard coded.

That's true unless it's in a back part of your base and you know nobody is gonna be around when you're opening it. The whole program is more for design than functionality. The whole thing is super insecure. I'm no goggle or yayhoo or what have you.

Hey. First off i think this key pad works great. I am using this for a drawbridge door. I have figured out how to invert the redstone signal but i need to be able to activate the door with 2 monitors. What do i have to add to have this work with a monitor to the right of the computer and behind?

you should make it "Ask for current password when you want to change password"
