      @bascule With a CA cutting bogus certs they can intercept (MitM), with exact private key they can intercept everyone without being detected

      @bleidl it's still an active attack though. The C|Net article implied a passive eavesdropper. The way TLS is deployed today that can work

          @bascule It would be interesting to know if they are asking for those keys or not since it would speak to capabilities and intentions.

          @bleidl @bascule unless the NSA asks for them regardless to deny us information about their actual caps.

          @marshray @bascule I'm surprised that NSA asks for keys at all rather than say gaining possession of them after they fall off back of truck

          @bleidl @marshray with a big bag of 0-days straight from Microsoft et al I'd guess endpoint security is a larger concern

          @bascule @bleidl 1/2 century of #NSA history suggests three things:1) They are very very good at not getting caught red-handed.

          @bascule @bleidl 2) #NSA greatly prefers passive eavesdropping to active attacks (see 1) whenever possible.

          @bascule @bleidl 3) But for Booz-Allen, #NSA is highly compartmentalized. Even those setting policy probably don't know all the capabilities

          @bascule In most cases I'm sure the NSA wants to decrypt years of sniffed TLS traffic, but there's also motive to ask Google for (FS) keys.
