Microsoft helped NSA spy on users
vendredi 12 juillet 2013 à 14:00Microsoft changed several systems to help the NSA spy on users. These systems include Skype, web chats, email, and remote file storage.
This means that Microsoft's claims about encryption and privacy in these programs and services are effectively fraudulent.
There is no US law requiring user software for encryption to have a back door. But you can't trust encryption unless it is done by a free program in your own computer.
