Usually, for Known Plain Text Attacks, we need to know at least a plain text and its corresponding cipher text, 
but in some occasions we can even analyze it without knowing the plain text, just knowing some details

To demonstrate this, I have designed the following challenge. To solve the challenge, all you are given is 
the cipher text, the algorithm and the fact that the plain text conta
