    Hackerz Only - Encryption Challenge

    Hi,
    I made a quick exe. When you click a button it gives you a number. If any of you can find that number, you are very smart . . . Because I encrypted the exe several times. I'll give you a few hints:

    I used some type of winzip, but a type of winzip that compresses and encrypts.

    Then I used blowfish.

    I will attach, in a .zip format. But, the file is not zip . . .

    Thanks all!

    So if i click on the button im smart?

    btw. With a topic title like that, do you expect anyone to download and run the exe without source?

    huh ?

    also if you mean source, like Private Sub bla bla then here it is:

    Private Sub Command1_Click()
    Text1.Text = " (number not showing because you find it)"
    End Sub

    If you mean .vbp and stuff, that would be giving the number away. Also, you said if you click the button your smart, yes you are, because in order to click the button you need to decrypt it like 2 times in some of the hardest encryptions invented . . .

    *edit*
    I know everyone doesn't believe this, but I have no eminence in hacking you.

    Also, its no exe. . . I told you, and I will say this again to enliven you people's brains. I encrypted the exe, so you cannot automatically click the button. Right now, its a .enc file in a .zip file. You have to unencrypt the .enc (in blowfish, *hint*) and then I encrypted it in some zip type thing.

    It may be impossible, but I don't know maybe some hacker can get past it. I'm not a hacker, and don't want to be one. I just posted Hackerz Only so I can see if a hacker can get past my work

    No, because that would be extremely easy to get past, since I told you what encryption it was. I was giving you a head start, the first encryption is blowfish, so you need to download a blowfish encrypter and decrypt it, then you need to get past something else.

    nah, i'm afraid its not, its a long number like 13 digits

    lol just tell me, how'd you get that number? it has nothing to do with it, did you press the button ?

    It is easy to get past BlowFish?? What are u talking about. Its impossible or at least it would take a very very long time. No one can crack a string encrypted in blowfish without know the key .

    And encrypting a string with multiple encryption algorithms is useless. It makes it no easier and no harder.

    Oh, I made a mistake, I was thinking of another encryption. My bad, I have like 12 different ones with like 4-5 different programs. Yes it is hard. But, it would be even harder if I didn't even tell you the encryption method. Because you'd have to guess which one and then find the source key or the key, whatever.

    My bad, hehe

    BuggyProgrammer, you might be joking, but I meant the Blowfish Encryption.

    BTW NuLLziLLa, the number is not 4829048672013

    Good try.
    Can you tell me what you did to find that? Did you make another guess like scrop?

    Thanks,

    Nope, for now on when you try to guess/know the answer can you tell me what you did you try to find it ?

    nah

    *huge edit*

    I don't understand why you guys are saying oh is that it and its not true. I told you, and I will enliven your brains again. I made a program, where if you click a button it makes text1.text say a 13 digit number. I encrypted that 2 times. So, if you are going to give me a number, it must be the real 13 digit number because there is no other way you can get a number.

    Thanks all, maybe this will help you understand. . .

    Im not working on it, got no time for that.
    If you used encryption apps it should be possible to crack the encrypytion, but why waste our time on it.

    Self made encryptions are harder to crack.
    If you wanna encrypt data,
    1. Encrypt to an unreadable format (just play a little with the ascii values )
    2. Mess up the file a little,
    for example (an encryption i use myself)
    take a buffer of 128 characters, take the first 8 and last 8 characters and switch them from place, take a few other characters and put them in mirror
    there are a lot of these funny things you can do with a buffer.

    Then let them find out what you did, allmost impossible because its not only encrypted but also the data is totally scrambled

    Have fun

    Hi,
    Your funny because maybe its a waste of your time, but maybe not others. Maybe people want to join the CIA and uncrack encryptions, eh ? Thanks for taking granted of everyones opinions and using yours.

    I think that was enough

    i know,

    i used to like encrypt things myself, its funny .... if you got the time.
    But i program for living, so i don't have time for these things.

    Maybe people want to join the CIA and uncrack encryptions
    you can also land in jail for decrypting without permission, so be carefull with that.

    I once join a kind of crack contest of a company that made an encryption, but they offered lots of money.

    So maybe you should also offer something to the people joining.
    I allready downloaded the zip but dint take a look at it, i will, but will not try to crack it if it takes tomuch time.

    What i do wanna know, is who the first will be thats can crack your app.

    Hi everyone,

    Personally, I think I put up too much of a challenge. I don't think anyone of VB Forums will be able to crack it. But, my key for blowfish was foolish. I'll just tell anyone who tries to crack it, which you can, its very easy to know . . . I know I said it in an unclear way, but if I made it more clear, you'd know. But I think to decrypt it you have to know how I did it . . .

    Thanks,

    I'm afraid not . . . You only got 1 number out of 13 digits right. Its the ten thousand column and its a 2.

    Unless you decrypted it the wrong way, causing it to screw up the code, giving you the wrong number.

    Make a simple encryption, once they cracked it, place an better encryption.

    This way you can make a real contest out of it

    I have a challange for you WaR_MaN3...

    1. I thought of a number
    2. I wrote an application that displayed a different number
    3. I wrote down the origional number on a paper
    4. I encrypted my application
    5. I tore up the paper with the origional number
    6. I opened the encrypted application in a Hex Editor and removed every second byte
    7. I burned up half of the pieces of the threaded paper
    8. I uploaded my now totally destroyed application to the Internet (just try to find it, it's somewhere around on the Net)
    9. I forgot what the origional number I wrote down was (and I also forgot why I even bothered to reply to this topic)

    Now my question is, how many pints of milk did I drink last year?
    .... and what the heck has this to do with VB?

    Hi,
    Clearly I don't think this needs any feedback . . . Its a stupid question. If you want me to come up with one ask me. If you are relating that to my post at the begining, then you have the worst brain for analogies.

    Thanks,

    Well, home-made encryptions are definately more easier to crack than blowfish or anything else out there. If this was home-made, Id give it a go. I wouldn't even bother trying to crack BlowFish. Your challenge is impossible. Not even the CIA could do it, sorry. You'd need to give us at least a couple of different strings, encrypted with the same routine and with the same key. You can't crack any encryption with just one sample.

    I think this is the most reasonable and pertinent response so far in this thread, since it makes more sense than the original post.

    Hi,
    Your right ordinary. I will make my own encrpytion sometime. Just takes some time. phinds, your a retard . . . your not funny at all. Plus, my post was better. That is impossible. If you forgot it, no one is going to find out . . . That is clearly impossible. My post isn't impossible. Its super hard though. Guys its common sense, the number to decrypt blowfish is 95681, the name of the .zip . . . lol. You change that 95681.enc (after decrypted) to 95681.CyT. Then you goto planetsourcecode and search for CyberCrypt 8.0 SelfExt. But, of course, no one is going to know its CyberCrypt. Anyway, can anyone try it now? hehe

    What I wondered is why you posted this in this forum. It's called "General VB Questions" not "Hack this encryption if you can".
