Skype makes use of AES-256 to encrypt its calls. Skype encryption has been cracked; and yet, I claim that AES-256 remains unbroken. What gives?

Well, it's the way that Skype's encryption was broken. What the computational linguists have done is best summed up thusly:

The simple description is: By looking at the size of the encrypted data packets you can guess what phonemes were spoken. Yes, that's all there is to it. They are just looking at how much data is sent and guessing what might be said that reasonably fits in that size. [Anonymous Coward]
There you go.

Doesn't SSL have measures to prevent snooping like this? This isn't the first time I've heard of guessing what's in the data by its size. I think SSL randomly changes packet sizes to prevent some of these methods from being used and see no reason why Skype couldn't either.

You couldn't be further from the truth. Governments have been trying to crack Skype for years. Skype was designed with this in mind...

I really hope people read a bit more about the technology before commenting on such things.
Skype uses industry standard 256 bit encryption and unless there is a flaw in the standard , the AES encryption by itself cannot be broken in the entire time the universe has existed.

He might have tried to hack the protocol which uses this standard but he still needs to get around the encryption which is impossible .Unless he has access to a hundred super computers which can try to guess every possible combination and key.Highly unlikely.

I read a post about someone justifying this because he will make it open source.
Iam sorry to say,but stealing someone's intellectual property has nothing to do with open source.

Wouldn't surprise me if the person who cracked it was a Bill Gates spy....

It won't ruin it for the end user... not necessarily, anyway. This makes it so you can write your own Skype-compatible client.

Of course, this also means that making Skype spambots is a lot easier.

He didn't crack AES... he reverse engineered Skype's protocol. You can glean this from the thread title.

edit: Oh, I guess you understood this. My excuse for missing that is I'm very tired Oh well, this is then directed at everyone else who thought he cracked the encryption.

Dear hackers.

Stop hacking all the services that i use and love, including Gmail, PSN, and skype.

I have lost all respect for the underground community behind them.

Cheers.

Microsoft didn't buy a technology they bought a name and a customer base. People around the world know Skype because it is called Skype not because of the technology behind it. All people care about is the fact that it allows them to communicate and any variety of technology's can accomplish that feat.

That said, they are screwed. I'm sure Microsoft cannot wait to insert unspeakable amounts of Bloatware inside the Skype service, using all sorts of known functionality that they would like to get in the short term instead of doing it right, rewriting some of their off-the shelf functions for the online world...

Hopefully i'll be proven wrong for their customer's sake. My opinion really doesn't matter. I don't use Skype. Many of my cousins do.
I've been happy with the lack of bloat in Windows 7 (or at least the reduction of it from Vista), hopefully that will translate to some of their other products.
