Outlook.com also now has Perfect Forward Secrecy (PFS) encryption, which Thomlinson said uses a different encryption key for every connection, "making it more difficult for attackers to decrypt connections."
PFS support has also been added to OneDrive's website, mobile app and desktop sync clients. "As with Outlook.com's email transfer, this makes it more difficult for attackers to decrypt connections between their systems and OneDrive," he wrote.
Thomlinson also announced the opening of the first Microsoft Transparency Center at the company's Redmond, Washington, headquarters. These centers will let "participating governments" review source code for key Microsoft products and verify that they contain no "back doors," he wrote.
The intention seems to be to assure foreign governments that Microsoft isn't giving the U.S. government access to its cloud computing systems in order to let it spy on individuals, government agencies and businesses abroad.
The Redmond center is the first of several that Microsoft plans to open, including one in Brussels that was announced in January.
