#258475 Krist - Minable currency that works across servers (paste updated)

Posted by PokeAcer on 26 August 2016 - 10:26 PM in Programs

Wait, Krist is harder to mine now? AWESOME I OWN SO MUCH /s



#251205 Krist - Minable currency that works across servers (paste updated)

Posted by PokeAcer on 30 April 2016 - 01:10 PM in Programs

73 pages? :o
I'm so happy we still are going!
Can someone TL;DR this for me? I'd love to go through 73 pages again, but my sleep schedule wouldn't :P
(I already have Krist and have the basics)



#240286 Pocket Computer Bug on Server

Posted by PokeAcer on 12 December 2015 - 07:39 PM in Bugs

It's a bug due to MCPC/Cauldron, and it won't be fixed due to that.
If you have to use them, look in the air, so you're not moused over any block.



#239961 Krist - Minable currency that works across servers (paste updated)

Posted by PokeAcer on 09 December 2015 - 04:36 PM in Programs

Well ceriat.net is back :P
@3d6 I suggest getting SSH on it if it hasn't got it (or VNC if Windows), and to get a few UPSes if it needs to be online all the time (connect your modem and/or router up to one too)



#239910 Krist - Minable currency that works across servers (paste updated)

Posted by PokeAcer on 08 December 2015 - 08:22 PM in Programs

3d6, you should get a dedicated VPS :P



#239780 Krist - Minable currency that works across servers (paste updated)

ceriat.net is down :(

Hey,
I had created a Wallet for Android! It would be cool if you check it out! :)

This is my first app, so it can have some bugs, but I found no one (except the date error :( ).

Features
  • Check you Krist Amount on your Android Wear or as a Notification
  • Check your Transactions
  • Save multiple Krist Wallets
  • Send Krists

You can download the apk here! or see the source code here!

Thank you all for testing!
Timia2109

Awesome man!
Maybe put this on Aptoide? I'd put it on my store if you don't want to, but I'll credit you :P

Awesome! As per usual, I am wondering if you are encrypting this in any way - maybe connect to the server on each connect, and it gets a random string from thin air and hashes it, so that each connector can use AES for it :P
From me tinkering with is, what I know is a client does a post() call, and that text appears on the screen.
Sounds VERY similar to a program designed for 3DS (homebrew)

This looks cool! Few questions:
  • Are you encrypting the RedNet data before sending, with something like AES? :P -http://www.computercraft.info/forums2/index.php?/topic/18930-aes-encryption/ is the AES API link

Thanks for the feedback :D

About encryption:
I want to implement AES, but the SquidDev's API isn't working in CraftOS 1.74 and I can't find a good and fast encryption API. Even so include encryption is one of my major priorities. Currently, rednet traffic is only Base64 encode...

About hashing:
Currently, the passwords are stored in server with a SHA1 hash. Next version change this with salted SHA256. Added :P
he fixed the api today

#232549 Door lock with Dynamic Password

^^^
You could make it download it and then tell users what to edit and where, or make the program do it for you :D

#232140 I started a small CC server.

Just saying, if you're using Cauldron (Bukkit+Forge):
DO NOT OP EVERYONE!!!!
Use a permissions plugin instead, it's more safer.



#231606 BlueBank v3.0

Alternatively, using diffe-hellman is a much better option I'd say. You can securely establish a new key with each connection, meaning even if an attacker somehow got a hold of the key, it would change next time you connected, rather than remaining the same for all eternity. Also, for computers to be able to encrypt and decrypt text, they both need to have the same key. The method you're suggesting seems to leave every computer with a different key and no way to share it securely.

My idea is this:
- Building has machines for money transfer
- Machines have wired network cable onto ONE floppy drive, with a blockbreaker (if you have relevant mod installed) on the cable right by the drive for security. one machine creates the file (the server) and then that is the key used via AES. If you need to reset due to compromization, you eject the floppy, then make someone go downstairs, throw the floppy away, then put a new one in to generate the key. It sends it via wired network cable (we will need to stop termination aswell) - the key is checked then removed from memory each time you change (so it connects, gets key to use, waits for message back, decrypts, then overwrites the variable)
- The blockbreaker is for if you think someone's placed a wire leading to their PC (griefing?), so you can securely break the connection.

About the DH approach

'You will have problem with Diffie-Hellman because calculations required for it to succeed use to big numbers for LUA to understand(300 digit prime)
I have unfinished version of this that went to trash because of such problem. I am working on workaround in free time (meta-tables rule!) but sadly no time estimate on this. Sorry for that :P Still good luck in future endeavors i am sure someone else can help :lol:'



#231576 Social Net API (CC's own social network)

Posted by PokeAcer on 31 August 2015 - 12:28 PM in APIs and Utilities

This is pretty cool! :D
I have already thought of many uses - perhaps server updates on a monitor which checks for one account (please make it so you can get a user's posts w/o having to login) and then display it on screen :P - then you don't need to use RedNet, or have people look on a website.



#231575 Advanced Password Utility

Posted by PokeAcer on 31 August 2015 - 12:09 PM in APIs and Utilities

Umm, AES encryption?
That's WILDLY insecure for passwords - you HASH a password, not encrypt it. Use SHA256 (I have the API in my program - http://pastebin.com/8fyFyw3B line 15-197) and a salt.



#231548 PXE Boot (Networked startup files)

Posted by PokeAcer on 30 August 2015 - 09:45 PM in Programs

View PostTiin57, on 30 August 2015 - 09:16 PM, said:

Well, the program isn't exactly designed to be run wirelessly. It's possible, but not recommended. I say that because the client will use the first PXE host it can find. If you're using a wired network where you know all devices, it's much more secure. Otherwise, someone can fire up another PXE host in range and completely disable whatever you were doing.

Yet you can set the host, so it'd still be good.
And you can still get into wired networks if you somehow glitch to place the cable down.



#231547 BlueBank v3.0

Posted by PokeAcer on 30 August 2015 - 09:19 PM in Programs

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Use a new key per install (generate on first boot from, IDK, a hash of the microtime and some random characters? (echo it in a PHP script + a random string generator) sha256 of course, just make the server handle this) then require that you insert a floppy disk into a *wired networked* drive for encryption - if you think people have compromised your bank and stole it, pull that out and make a 'reset key' functionality which recreates the key and sends a message to the client to shutdown.

And maybe make a key using the script aswell.

I've made a script that will function perfectly for keygen:

#231543 PXE Boot (Networked startup files)

Posted by PokeAcer on 30 August 2015 - 08:59 PM in Programs

This is pretty cool, but,
maybe make the the program encrypted using AES (http://www.computerc...aes-encryption/) so programs aren't transmitted in plain-text OTA (example - door lock)?



#231541 Door lock with Dynamic Password

It rather is insecure from that standpoint, but as I said in the code, the algorithm to generate them can be changed
Problem is, I can't encrypt it or else I wouldn't be able to decrypt it for it to be shown (assuming one-way encryptions like SHA-256).

http://www.computerc...aes-encryption/
^^ use to encrypt data. Maybe make a fully random string, hash it x times with sha256 and then use that as the key - don't even store the key on the machine, store it on a connected floppy drive *inside* the base so people can't get it.
