shadowslayer> my dad won't give me his credit card number
Parents... sheesh! What if you let him type in the credit card number and submit the order himself while you're not looking? Also point out the message that " Your credit card data is completely secured and encrypted using the latest 128bit security."
if you can crack the code, why not just hack yourself a membership?
shadowslayer, here is a paragraph of English text encrypted using 128-bit AES. It begins "Dear shadowslayer" and contains 59 words. Enjoy! :)

Heck, I'll even offer a prize. If anyone, individually or in collaboration with others, correctly decrypts the entire paragraph above before 1st March 2008, I will buy shadowslayer a 1-year gold membership to chess.com. I will be the judge of the results since only I know the original text, and my decision is final and binding. ;)
I'll hold you to that :)
But I want the sub...
*opens google*
Lol I love a good challenge...

Your search - "how to crack 128-bit AES" - did not match any documents.
:(
Since I I have no chance of actually cracking that code, I have to resort to testing my phycic (how do you spell that?) abilities:
"Ok, I admit it, it's possible to crack 128-bit code. No doubt you managed to somehow find a mathamatical flaw in the way the code works. Well, Congrat's for that. Now lets' go on in life. Did you know that hippos enjoy eating purple flowers?! Anyways, I lately played against Garry Kasparov. I was White. It was a version of the Kings gambit I made up. It went: 1.g4 e5 2.f4 exf4 3.h3 Qh4#"
Imagine I actually got it right!
Itaibin, impressive! While your psychic abilities may still need some fine-tuning, that's closer to the original than anyone else has gotten.
4=A or I
+=space
/=space
close?just from one good look!
MASSAVEE BREAK THROUGH!!!!! caps only :-)
I just want to make some groups I'll pay $5 and for a month so I'm fine

Alas, the romantic days of cryptography are over. In the 1800s and earlier, codes often worked exactly like that. Alphabetic and polyalphabetic substitution ciphers were all the rage--and a skilled codebreaker could use letter and word frequency analysis to eventually break the code. James Kahn's "The Codebreakers" is a wonderful read, if you can find it.
But now everything has changed. There are public encyrption algorithms like DES, 3DES, and AES... and hashing algorithms like MD5 and SHA... and the only way to break them would be to solve complex mathematical problems or have access to computers faster than any known to be in existance, at least when a sufficiently long and hard-to-guess or random key is chosen by the end user.
From time to time, foolish companies make the mistake of deploying a 'secret encryption scheme', and those tend to be much weaker than the tried and true public ciphers, but that's the exception rather than the rule.
Even the existance of an encrypted message is easy to hide these days, at least from the unsuspecting, using technologies like steganography. Basically, you can hide a message within the noise of a digital photograph!
I don't want to cough up $30 and my dad won't give me his credit card number even though I'll pay him but he will do pay pal.
