#242822 MD5 Hash

Posted by Noodle on 10 January 2016 - 09:32 PM in Programs

I also want to note that the computing power of the Computercraft computers is not enough to crack any hash.
Also, Make a passphrase because not every word/phrase is cracked in md5 yet, you just have to find the one that isn't.
Using my website, your MD5 converted query will not be stored to any database.

MD5 in insecure. Consider using SHA256+salt. Also, you made a website to convert the password the user types in to MD5. Worse yet, the password is sent with the URL. This means that anyone with access to

The Minecraft server
The Minecraft server's local network
A server between the Minecraft server and your website
Your website

could read your password in the end of the URL. If you ever need MD5 in Computercraft (hint: you don't), find someone who has ported MD5 to Lua, and use their code. But you don't even need that. Just use SHA256 (like here), and a salt.

I would actually like someone to make this.

#242781 MD5 Hash

Hello again, it's been a while..
I quit Minecraft then I kinda came back for like all of a few days on my friend's server and I needed some security for my computer so nobody messes it up..
I found this quite useful, you can use it how you would like..

I wanted to hide my password from the people on the server so I figured I'd use md5 in order to hide it.
I made a website to convert my queries into md5 and echo the output.

Example: http://pastebin.com/diMwJXuy

How it works is you request a query to the website using 'cn' as the GET request.
So, as in the example, I have the computer make a request using the convert link, the website outputs the query in Md5 and if check it with the password.

The way you can use it is going on to a website and converting your desired password into MD5 (or using mine) then create a variable on the computer called password with the md5 hash encrypted password as the string.

local convertlink = "http://md5hash.netne.net/md5.php?cn="
local pwd = '098f6bcd4621d373cade4e832627b4f6'

Then do the normal input = read("*") stuff, and create another variable for the link.

local input = read("*")
local s = http.get(convertlink .. input).readLine()

That will read the md5 result from the website and set it to s..
Then do the normal "checking if password is correct"

if (s == pwd) then
    print("Access granted.")
end

And that's it.

You can use the website for anything other than that too.. it doesn't just have to be password programs, but I can't imagine there would be any other reason..
Just remember: convertlink is "http://md5hash.netne.net/md5.php?cn=<your_request_here>"
