600€ de gain en PB !!!!!!

[SPH]

Hi,

I finished coding my file encryptor.
As I think it is unbreakable, I offer 600€ to the first person who will decrypt a file.

Everything is explained here:

Good luck...

If do you want to keep the crypted algorithm safe, better not challenge hackers

Come on, I'll help you by giving you 5 files and an indication of the number of bytes in the original file (See the site)

If you encrypt multiple times, just "remixing the keyword" in some creative way, it would be VERY hard to decode… but that's not very good for "real time transmissions"…

As I think it is unbreakable, I offer 200€ to the first person who will decrypt a file.

If you're so confident, post your challenge in https://www.reddit.com/r/crypto and be prepared to lose your money. I'll be watching that site to see if you posted it.

What algorithm do you use? And don't say you don't wanna tell anybody. Security by obscurity just makes no sense.

Edit: I just found the source code, now the challenge makes a lot more sense.

But I will summarize it here:
I give the crypteur.exe and also the .PB
You can examine it as precisely as you want, do debugging and other to understand it.
On the page, there are also 5 results of the encryption of a TXT file. 5 results using the same TXT and the same passwords.

It's up to you to make the cross-references

You still have 3 months

So do you have found something ?

I already heard this sentence but no one could ever demonstrate it. Please can anyone demonstrate this dogma.
Thank you.

Only 2 months left to find!

I'll give you some secrets here:
- There is no red key
- a key is a piece of decor present only once on the site
- I like Nirvana
- the password is almost a sentence present on the screen

Phew, maybe I said too much...........

I'm just curious. You write "encrypts your data with a monstrously large key.". What is the difference to a One Time Pad, which is in general nearly unbreakable? (https://en.wikipedia.org/wiki/One-time_pad) It is much more easy than yours and just needs some XOR function.

The most crypto algorithms like AES are cool because they use a "short" key of only 128 Bits to encrypt with high security. If I do passwords neary as large as the content, a simply XOR encryption may even be extremely secure (a One Time Pad). So the hard part in encryption is to have a good balance between minimum key length and being resistant against brute force (simply trying all possible combinations).

So a short key of only 32 bits is an easy target for brute force. 1024 bits is simply to much to handle (keep it small, eg for small chips on cards or small bandwith etc). Today, 128 bits are hard to break with brute force, if the algorithm is strong. So 128 bits is the perfect balance today. Small as possible and highly secue algorithm. Some say 256 is needed today, but anyway.

So having some "monstrously large key" is usually not what is needed in real life, right? So why this?

I also can't find your challenge on reddit r/crypto, which would be the first place to ask such. They will give you some better insights in pros and cons of your algorithm than we here will ever be able to.
