I wish people like cnn would do more research, or ask an encryption expert. I could produce a dozen encryption systems which are fatally flawed, yet impossible to hack given only a page or so of encrypted text. The challenge comes when people A) Know the algorithm. B) Have Gigabytes of encrypted text. Because there is no way you will ever keep your algorithm secret once you release the software, and people will encrypt lots of text. I am sure under these circumstances, their encryption will fall very quickly, unless the underlying basis is one of the existing good encryption systems (which I doubt). EDIT: Found the following hilarious clip of text: "We make you a deal: We will reveal our algorithm the same time when Google reveals theirs. Does the fact that Google does not reveal their search algorithm make their algorithm questionable?" The very idea that google not sharing their search algorithms, and these people not sharing their encryption algorithm, are the same thing, shows either these people fundamentally misunderstand encryption, or are frauds. Or both.
