"Over the weekend, German news outlet Spiegel published a story about the NSA’s ability to crack encrypted forms of communication, exposing the agency’s routine interception of SSL/TLS, which are used by web servers to transmit sensitive information. The report also exposed the fact that the agency has the ability to decrypt a virtual private network."
"... more significantly, ... documents leaked by Edward Snowden show the forms of encryption the NSA struggled to break (at least at the time of the documents in 2012). That list includes PGP, Tor, CSpace, OTR and ZRTP."
"Another alarming statistic ... is the number of https connections, the type of secure connections used by sites like Facebook, that the agency intercepts. One document showed that by late 2012, the NSA was cracking 10 million such connections a day."-TechCrunchKnowledge is key
