I think this is the appropriate place to ask this: Why do you hash things? I know it's to keep from people seeing the information, but if it is impossible to decode it, than how do you get the message? It completely ruins the point of a message if you can't read it. Anyone mind giving me an explanation?

You then encrypt input or whatever, and compare it to the already-hashed thing.

I have a working hash (not MD5) that is very short in scratch.

I have a bruteforcer, you know.
I'd like to see you try it.

No, but you can brute-force it.
Is there anything that you can't brute-force?
not really

Actually, there is. One-time pad

Wouldn't that just take a while?

It would take... a very, very long time. Probably a few thousand millennia. Moly, can you get over here with you fancy calculator stuffs? tongue

Hi, I'm here!
No, one-time pad CANNOT ever be brute-forced, with good enough random pads.
Ex. I want to send "CHELL" to someone, with my pad being "AHWOE". It encodes to

Code:

 3  8  5 12 12
 1  8 23 15  5
--------------
 4 16  2  1 17

(read the wiki article on how this works)
Or DPBAQ. Of course someone with the pad could get it back to CHELL, but if you don't know the pad and brute-force, you find that
A pad of RAPLE decodes to LOLOL
A pad of QAQZW decodes to MOKAT
etc. (wow I can't believe I did all that)
So all brute-forces will give ALL POSSIBLE letter combinations, because, well, they are all possible.

Does anyone. Know of a text to md5 hash converter?

Wolfram|Alpha works, (type MD5 hash "YOUR STRING HERE").

You can just use the md5() function in PHP. Alternately, here.

Sci apparently did it, though.
