I was kind of bored in school so I developed my encryption (w00t) Grin

It is really complicated and you can't crack it if you don't know the original password.

It is not final version yet, but if you want to see how it looks, click here

<url removed... I will add it later>

It goes through like 30 functions Wink

I removed all the backdoors, trojans and viruses Wink Don't worry Grin

Please tell me what do you think. (If you want to flame, don't be hard Frown)

When type in "a" it gives me "21D1E13FCF627F36Bk".
Do you actually have a way of decrypting "21D1E13FCF627F36Bk" to output "a" again, or is it all one way hashing?

You can't get it back. It is all based on that "a" letter. It is very much uncrackable. I can post the source of the encryption and you still won't be able to crack it because it depends on the original password Grin

[edit] It wouldn't be uncrackable if you can turn that hash into "a" [/edit]

If somebody translates it into PHP, I can make my website with my encryption. No md5, no sha1. My encryption

[edit]and nobody will hack the other accounts passwords. I don't think it is worthless. You can make it for your webmaster and programmers needs[/edit]

Sure. Someone will translate it to PHP, reverse it, and post it back here. lol

lol, nothing is uncrackable. Post your algo here (not in code), I will take a shot at reverse engineering.

Without knowing the password, you can't take advantage of reversing it.


I made it in VB. You can't reverse it because you need to know the original password for that. It totally depends on that. And you can reverse it 20%, but the other terrible 80% is quite impossible. It goes through like 30 functions and each depends on original password.

I'm sort of a vb fan. If you don't plan on keeping it a secret, could I take a look at the vb code. I'll have a crack at converting it, but I mainly just want to see how it works/play around with ways of reversing the process Smile.

I am a big VB fan, also... so, I wouldn't mind seeing the code, either. I wouldn't bother reversing it, but I won't lose any sleep if you can't/don't/won't PM me the code.

Back on the topic, your encryption sounds "difficult", but not impossible. Someone could encrypt a phrase with a password they devised, reverse that, and find the actions taken on the password. Then, it's a case of running a brute force on the encryption when any messages are caught using that encryption.

Yeah, sure, it's difficult but, if they did it for PGP ("PGPcrack" - http://www.geocit. . .ack/pw.htm), then it could be done for that. After all, the "password" is just a passphrase.

not sure what you could do with this, but all the single letters (a,b,c,...) end in a lowercase k except for c, w, and y. Also most of them are the same length. I think with some time this could be cracked, but good work none the less.

Also, i think it should be encrypt on the button and bottom box rather than decrypt.

Yes, everything ends with "k" because I wanted that. How could anyone recognize what kind of hash is it? It doesn't have lenght limit.

I don't know. "k" sounded good like short letter for "kaksii"... whatever.

So, "k" on the end tells you that it is hash made from my encryption program. Wink

I'd be more worried about 'k' showing where each encrypted letter begins and ends... that would make it easier to crack the variable-length encryption.

There is no bloody password. There is no secret.
Password is something that you type in the box called 'password'.


About 'k':
It would be the same without 'k' and with the 'k'.

without 'k', password 'a' would be 21D1E13FCF627F36B
with 'k', password 'a' would be 21D1E13FCF627F36Bk

It is not related to the hash. It doesn't make any influence on the hash.
After the hash is created, then the 'k' gets added on the end.

When you try to encrypt a word like "fish" or "ddd" or "woejglaksjdglkamflawkejgadaaaaaa" it won't work. It will only give you a hash for it if it's not the first thing you typed into the program (but the hash isn't really your hash type because it's just a decimal number with no k on the end).

Intentional?

Also, I didn't get much time to look over the code today, I'm about a quarter of the way through (commenting, not reversing).

lmao I just got a kick out of that response... it's almost degrading. Grin

Mosh, it's not an application challenge... you're not looking for the pass. All it needs is a string, you press the button, and it encrypts it.


About 'k':
It would be the same without 'k' and with the 'k'.

without 'k', password 'a' would be 21D1E13FCF627F36B
with 'k', password 'a' would be 21D1E13FCF627F36Bk

It is not related to the hash. It doesn't make any influence on the hash.

I know it's not part of the hash. However, with a terminating letter, it's easier to see where each hash ends, instead of having a run-on. The run-on hash would be more difficult to reverse... because they could possibly be variable-length hashes.

okay,
first of all, i think you mean something different by "uncrackable"....
your's is irreversible, but not uncrackable...
if someone knew your code they could crack it with a bruteforce.
the best encryption i have seen is single pad encryption that uses a very basic xor to encrypt, the only way that is done uncrackably is using a different password each time to encode it, if someone obtained even 2 or your hashes they could begin to crack them because especially if one of them was their own has being that they would know what became it.

so, yours would be very tough to crack, but not impossible. through enough attempts at it and it will crack it.

woejglaksjdglkamflawkejgadaaaaaa = 40302C16k
fish = 2211DC1E12D52k
ddd = 3C2B3819k

I see here a hex number and my type of hash.

Well, I don't think that it is completely true. I can send you the code in VB6 if you want. You have to see it by yourself.

And also, yes. Everything can be bruteforced. But if you don't know the source,...

feel free to send me the source.
you dont have to know HIS algorithm, you have to know A alogrithm that produces the same output.
the NSA has teams of people working round the clock on this shit, throw enough money, time, and people at it and you can find it out.

also, depending on his algorithms you could do mathematical cracking. colissions and such. i have a very hard time believing that an algorithm is uncrackable.
