Why even bother trying? The New York Times reveals:
The NSA is winning its long-running secret war on encryption. Below are encryption tools the agency has had some success in cracking, according to documents provided by Edward Snowden.
Virtual Private Networks – Commonly used by businesses to allow employees to access work networks from outside the office, via an encrypted “tunnel” through a public network.
Encrypted chat – Available with chat programs like Adium or with software added to programs like AOL Instant Messenger, providing “end to end” encryption, in which the data cannot be decrypted at any point along the transfer (even by the messaging service).
Encrypted Voice over Internet Protocol – Services like Microsoft’s Skype and Apple’s FaceTime allow users to make free, encrypted phone and video calls over the Internet. The documents suggest that the N.S.A. is working with some VoIP services to obtain pre-encryption access to such messages.
SSH Secure Shell – For Linux and Mac operating system users, this is the standard way to gain access to a remote computer.
HTTPS (Hypertext Transfer Protocol Secure) – This has long been a standard way to encrypt password and financial information when sending information from a computer to a server, and it is becoming more common with social media sites like Facebook and Twitter and Webmail services like Gmail. A URL that begins with “https://” and displays a small padlock icon designates a secured web page.
TLS/SSL (Transport Layer Security/Secure Sockets Layer) – The most common way to secure information sent over the Internet (including Web browsing and e-mail) and internal servers. HTTPS is secured by applying TLS/SSL to a Web site.
