Security through obscurity is a bad idea.

Just because a couple of people can't crack it doesn't mean there's no flaws, and seeing multiple messages or having some idea of what the plaintext is can expose massive holes.

I suggest you share what you use to generate it, and talk to a cryptography community - we don't have much of that here.

I am merely posting what anyone would see, if they obtained my encoded text. They would not have any background data, or any other source of information to go by. Thus, I refrained from providing hints and tips. If no one is up for the challenge, I understand. However, my intentions are to see if one can grab anything from the said raw text, without using any tips or hints

Only if there is value in hacking into a victim computer like a bank or a company secret valuable database, if not then it is a large waste of time for a professional hacker to get into.

CWEric - My main concern is to see if there can be information obtained from the raw text, thus showing security flaws.

Say that this was an email, getting snatched, now analyzed, and hence the cracker would not have anything, but the shown text.

If you can point me to a better place for this challenge to be accepted, I would appreciate that extremely.

security.stackexchange.com might be worth looking at, but will likely tell you much the same as we have.

They would likely get a large number of other emails, along with more context. They could also get any other data stored on the same PC, including the generating software but hopefully not the keys because they shouldn't be stored. They now know everything about your 'encryption' system except the key. And they know what (potentially flawed) PRNG you used to make the key.

An encryption system is pretty useless if you can only use it once, because you then have to a) design another, and b) get the details to the recipient without them being intercepted (though one-time pads are a slight deviation on this idea).

You're arguing entirely from security-through-obscurity, which is a very bad idea.

Be that as it may, say that my machine was not attacked, but in fact this was on a simple piece of paper, thus it would not contain anything else. Now the person who now has my encrypted text would in fact try to gather more intel, although they would not just sit around twiddling their thumbs in dismay. My question to you all, is what does my text say? And, where can I find people who want to accept my challenge, instead of giving me speeches on security. I am looking for flaws in my encryption, not here to learn about the proper way of security. The proper way of security is stop using computers, which are easily accessible, and go back to typewriters, or simple pen and paper.

That's not how you audit security. It's like declaring a bridge safe because you drove a car over it once.

The proper way of security is stop using computers, which are easily accessible, and go back to typewriters, or simple pen and paper.
Properly done, computers can be way better than pen & paper. Humans are notoriously useless at picking random numbers, and pen & paper is known for leaving an imprint on the piece(s) of paper below it.

Typewriters are even more vulnerable to listening attacks than keyboards, I imagine.

And, where can I find people who want to accept my challenge, instead of giving me speeches on security.
I don't know. I gave you one option, but anywhere reasonably security concious will laugh at you because you're going about this completely the wrong way.

Okay, so how would you go about doing it?

Also I would like to point out, that computers are pseudo random, and not truly random. It would be more secure if I went in a library, went through fifty books, gathering their page numbers for my random numbers. A computer uses an algorithm, and thus it can be found out in due time.

Keyboards can have hardware keyloggers installed in them, thus giving an extreme vulnerability. In fact, if we want to go down that path, ones every move can be watched, and no privacy allowed; cameras everywhere, microphones picking up anything audible, and so then nothing would be safe.

Paper does leave an imprint on the surface of the written transcript, however if one is knowledgeable of this simple fact, they then can take precautions. Paper needs hands on. Computers, not so. That is all I meant by saying that paper is much more secure. You cannot access my code on a paper from across the world, although you can with a computer.

I did take your advice, and I posted there as well. Like I have said before, this is not about auditing security. I want to see how this would be assessed. I am thrilled to see that this code didn't get cracked easily by some online tool, and that it is still being observed. This is not the only place I have posted this......

Many OSs now have cryptographically secure randomness sources built in. Intel (probably AMD too, not sure) has them built into CPUs, and many drivers for e.g. radios now collect atmospheric noise.

How do you select the fifty books, or the page numbers? Which ones look eye-catching in the right way, typically.

Social engineering is a pretty major component of most security breaches now. Ringing someone up and asking them to urgently mail you a document works remarkably well.

The only reason you'd do this would be as a PR stunt. It's worthless otherwise.

Most online tools won't pick up anything more difficult than a simple substitution cipher.

Alright, I see that you have no interest in trying to figure this out. I thank you for the debate.

I have to disagree with you on a lot of what you said.

Computers are built by large corporations, Intel especially has backdoors built in their CPU chips, you can find this out easily. It is used for remote access support. To even think that computers are more secure than pen and paper, is extremely laughable.

You are correct about the social engineering aspect, however if it were me and you talking to each other with this encryption, then why would a social engineer have anything to do with us? First thing is, stay off the radar. Second, learn your security, taking all precautions.

I am not here to debate the proper way of security, and how to go about it. All I am interested in is if there is a way that the message can be found, and how one would do so.

Did I say that it convinced me? No, I did not. I put forth a challenge, and none of you have provided me with any useful data acquired from my text. Either you check it out yourselves, or move on to more important things. Stop putting words in my mouth, saying things that I never said (mdd1963).
