Hey!
My solution is not excepted although I'm sure it's correct. I got the complete plain text so the answer should be ok, too. Would be nice if someone could check if there is a typo in the hex code.

The answer isn't hex. Once you find the plaintext, you should be able to go from there

I know that the answer is not hex. As usual the answer something in English. I meant the hex which is given in the challenge. I checked the plain text twice now and everything fits quite nicely.

The entire plaintext isn't the answer either.

I just checked, and the ciphertext on the page right now decrypts fine, and the answer it gives is accepted by the site.

Unlike some of these, I can't see any way you could get something which looks correct but is actually wrong. Hmm. If you want, you can PM me your answer - but I'm not sure whether I'll be able to say what you're doing wrong though.

I know that, too! As in most of the other challenges the answer is not the complete text but just a part. In this case I got something like "xxxxxxxxx". So the answer should be xxxxxxxxx.

I'm just not getting something in the code, the use of the Member by Pointer operator " -> " is confusing the hell out of me. Is it supposed to represent something else in the context of this code?

the 4 bytes from txt[x] to txt[x+3] get XORed

Hello There,

Can you tell me how you know that

(txt -> txt[i + 3])

is the 4 bytes from txt[x] to txt[x+3] get XORed?

There is some standard about it?

I just have doubt about it ...

Yes " -> " means from txt[x] to txt[x+3] (4 bytes).

I know this because i've solved the problem and can verify thats what it means

ok, i just had the doubt ... usually the "->" denote a pointer member from an object ...


But thank you for your replay

I have a i5 processor and just guessing the four bytes key with a c program of 50 lines is taking a couple of minutes
By brute force it takes around 3 min of program running.
