Microsoft says it doesn't give NSA secret encryption keys

Microsoft, addressing persistent concerns that it has helped the U.S. government gather customer information, said it doesn't provide direct access to e-mails, instant messages or Skype calls and refuses to grant agencies the ability to break its encryption. In a letter to U.S. Attorney General Eric Holder, the company asked for permission to share more information on its communication with government agencies, saying it has a constitutional right to do so. Microsoft said such permission has been delayed and asked Holder for personal help.
