The longest key in the world won't protect you from a FISA warrent.

  What. A FISA warrant doesn't magically render RSA invalid. If all your comms are encrypted, they can get whatever warrants they want, and they still won't be able to read your information unless you surrender your passphrase and key.

    They can, and do, force you to divulge your key.

      I understand that they can, and sometimes may, force you to divulge your key, but it's not a consistent thing in the United States. There are judgments that require the divulgence, and judgments that claim such forced divulgence is precluded by the Fifth Amendment. In any case, you buy yourself a very large amount of time if you don't just leave all your communiques out for them to read in plaintext. If you're encrypted, you have a lot of due process to exhaust before they ultimatley MAY order you to divulge the key. They have to go through your lawyer. He can file motions and appeals. The accused may incidentally forget the password. There are a lot of options. With plaintext, there are no options; there is only the government with all your content, and you with no control over anything. See this here, with reference to the conflicting case law in the U.S.: https://en.wikipedia.org/wiki/Key_disclosure_law#United_States https://en.wikipedia.org/wiki/Key_disclosure_law#United_Stat...

        The point is really that they could just change their mind. It's already obvious that the gov't will go to great lengths to violate privacy and what we assumed were constitutional protections, so why would they respect your 5th amendment right and not just demand keys in the future?

      That's what happens with extraordinary rendition, not FISA warrants.
