This was one of my projects that I did with a classmate during my coding class. It was based off of an old algorithm that he made up during elementary school and we both decided that it would be pretty neat to turn it into a program that is easy to encipher and decipher.
Text: We the people of the United States
Very nice! Would you mind explaining how the cipher works?
Sure, I'll go through the ciphering process
Input Text: Hello World!
Encryption Level: 5
First, the program splits the text entered into a number of lines that depends on what the user types in for the Encyption Level field.
The number in the Encryption Level field tells the program how many characters are in each line.
So, if we rearrange the text into this format, it would look like this:
The program then replaces spaces with ` and extra space on the last line with ~ until the number of characters on the last line is equal to the Encryption Level (5).
Next, the program reads the lines downward like this:
And finally, the text is reversed and it is done.
One of the only flaws with my ciphering program is that if the user types in ` or ~ as some of their characters, it assumes that they are spaces and filler spaces respectively. But since those characters are rarely used in normal conversation, I don't think it should be a problem.
Interesting cipher, kpa! Reminds me of the cipher game we had going on here some while back. I made a couple of pretty simple ciphers myself, such as this little one:
Thou shalt honor thy Brother, protect thy Mother, and take thine Father to ye olde ball game.

I.. uh... don't remember how it works off the top of my head anymore, though
Ahhhhh, very clever, kpa.
I've used that kind of cipher before. And you should indeed check out the topic that Tsukasa is referring to and perhaps consider bumping it:
Wow, after viewing all of the ciphers that yall came up with, my friend's cipher feels very insecure
I'll be sure to show him all of the ciphers that you guys were able to come up with because he is really into those types of things.
The credit for the original algorithm should go toward my friend, I was just the one that programmed it.
Also, I am interested in that other thread. I have no idea on how to even start with weregoose's cipher, but in the meantime I think I will try to come up with my own difficult cipher.
