The Skype protocol has been reverse engineered
 

Skype has been in the news a lot recently, mainly due to rumors of it being acquired a few months before a planned IPO. We thought Facebook and Google may pounce on the company for as much as $4 billion, but then Microsoft turned up, put $8.5 billion on the table, and walked away with their very expensive prize.

Now Microsoft own the most popular VoIP service out there, and surely plans to make it an integral part of their operations and products going forward. At the same time, one researcher has decided he wants to make Skype open source by reverse engineering the protocol the service uses.

In fact, he claims to have already achieved that reverse engineering feat on a new skype-open-source blog. The source code has been posted for versions 1.x/3.x/4.x of Skype as well as details of the rc4 layer arithmetic encoding the service uses.
