Can you break my code?
Hello folks, jumper_0 here! I have entirely revamped my system of encryption based on the previous code I made. This is the second ever encryption method I have made. This one makes me sad, because I had to inhibit the security of it to test some things, but it will be very useful. I could have made this super complex and hard to decrypt, but I need to make it secure as well. I dont want any small loops in it. Anyways, make of it what you will! This is only my second code... Can you crack my code?

After a week, If no one can crack the code, I will post the second half of the code that is hopefully REQUIRED to crack it. Good luck! the more ways you try and crack it, and the more people you get involved in this the better!
I forgot to mention, that please post your progress when ever you make a breakthrough, in a spoiler so that i can figure out the best way to make it more secure, and also post a comment when you start work on it, and your initial thoughts.

Given that spaces and punctuation seem to stand for themselves, and the very non-uniform distribution of letters,
I'd say this is just a substitution cipher.

I suppose you could say that... Although if you manage to discover the answer just from the text i will be very surprised and sad. My objective is to make this nearly uncrackable with out the second part of the code. that is why im not posting the second part yet.
OKAY, someone cracked the first line of the code, but is stuck on the rest of it.

It's not just a simple substitution cipher. I just ran 'HQMDGXEXGEHX' against a dictionary of 12-letter words and found no matches.. I mean just testing for matching letters within the sequence, eg all the 'X' characters have to be the same in their pre-encrypted state.

ha-ha it is more secure than that! anyways, i found a place with some very, very intelligent people who cracked nearly every single word, but the part that i was testing for was never found out, and they had some trouble with other words. Any future advice would still help greatly! I am well on my way into creating the hyper secure (but still not as secure as i could make it) version three, and holding back on possibilities to make it even better by removing flaws from version 4! i have decided the call this code the 'BCcode' for various reasons. enjoy!

Well, an easy way for me to say that doesn't work like that is that i really dont care what you say unless you can give proof? im not doing this to use it, im doing this for fun. I'm releasing code that is MEANT to be decrypted, and has been both times. I'm doing this to learn about how encryption works, and i am pretty sure that this next one will be entirely uncrackable with out the second part of the code... If you can write out what it means in English, than you can read it. I dont go on word, i go on proof.

you'll learn a lot more about cryptography if you have people look over the actual algorithm and discuss it with you. This "crack my super secret code" stuff is more of a child game. It might be interesting for puzzlers, but I'm afraid it's not very interesting for people who are into cryptography, because you don't have any elegant algorithm or fascinating idea to offer. Just the 500,000th version of some secret homegrown "uncrackable" cipher. What does it do? What makes it secure? Nobody knows -- which is kind of boring.
I don't know where people got this idea of keeping crypto algorithms secret from. Maybe they've watched to many bad movies. In reality, you want the exact opposite: You want your algorithm reviewed and tested by as many people as possible. You publish a paper on it and put an example implementation on your home page. If it has survived all the reviews and tests, then it's good.
Anyway, if you just wanna do some puzzles, keep going.

I am not really doing this for anything specific.. but what i really want to test is how easy it is to crack without the key... that is my objective, and i got exactly what i wanted out of this code on another forum - they solved it, and told me exactly what made it easy to crack, and what made it difficult to crack. The first one was a glorified substitution cipher, with some extra bits stuck on and a really cool way of getting the alphabet, this one uses that a bit more and took longer to crack, which is what i want. My next one is.. well, its an actually difficult one to crack, and it should be quite impossible without the key code. and even then it is very very difficult to crack. The next one is the one you want to look at if you really want to test your abilities. :I

I have read many of your wise lines. I have decided to do exactly what you suggested and like you I believe keeping an algorithm a secret goes to the puzzlers not for people into cryptography.

Be as critical as you have always been and see if there is something there. Note the example on the site is the most fundamental of what could be achieved for the highest entropy of data.

could you tell me what forum you went to that cracked it? I have a code I need cracked lol.. also, I did decipher this code. can I pm you how?
