Thanks dude. I appreciate it. I just need to do the 'things on code

And the translating in PHP will start. B)


Whats up now? Nobody can't find any bug? :happy:

It worked fine for me with a 200 char password Smile

good job, now I think that it is very unlikely for it to break on any input.
I tried it with a couple of thousand different inputs including all the 255 ascii chars up to the length 200 and it didn't break Wink
now you should be worrying about collisions :happy:

Collisions yeah Frown


Can you please check again. I added one extra line to the code, so nobody knows the latest source.


Please check

It would be kinda difficult to eliminate collisions after making the algorithm. Wouldnt it be wiser to design an algorithm to be collision-free?

@kaksii - would you be overly upset if I wrote a bruteforcer in MASM?

Just a proof of concept.... be a good reversing exercise. Having said that, I'm a little short of time right now so it may not happen for a few weeks.

I'll work from the latest .exe in this thread.

I am begging you to do that.

But you should know that it will be translated in php, there will be no use in bruteforcing it.

And also, you can bruteforce it, but it is not what people want.

People want solution how to crack the hash. Not to bruteforce it.

But you can try. Good luck Wink

The whole point of a hash is that it cannot be reversed (as yours cannot).

The only method of attack (apart from full cryptanalysis) is to bruteforce it (or use pre determined rainbow tables).

I'll code the brute forcer at some point..... seeing as you only use basic string manipulation it should be reasonably quick to brute a key length 0-6 or 7. It wont be optimised but it will give a solution.

I'll update when I get some free time and work gets less hectic.

You won't be able to bruteforce it in php

I hope you won't


I'll make something to stop bruteforcing Wink

you can't stop bruteforcing. Sure, use a chain-block method. Still is bruteforcable. You can just make it take so long to bruteforce that the sun will be gone by the time you decrypted it with current methods available.

For example.

I have website with my encryption system.

Dude wants to bruteforce the login box.

I put limit on 10 allowed wrong passwords and after that, dude is
not able to login for 5 mins.

It is still bruteforceable, but dude will have to wait for about 10 years to crack it.

What do you think now?

too easy, i set my script up to change proxies evey 10 tries. so my IP changes, and the block is effectively lifted.


ZING!

You'd still need a lot of working proxies though

Nice zing. :happy:

A better alternative might be to lock the account after a number of failed attempts for a particular user account, not an IP.

They'd just need to be tested as working first, but...
