Be sure that you are aware of the laws on where you travel to. In the United Kingdom, the police can seek a warrant that requires you to either decrypt a specific piece of data or to surrender any encryption private key or password under Part III of the Regulation of Investigatory Powers Act 2000. Refusing to do so under this act is a criminal offence with a sentence of two years in prison (longer if they allege that the encrypted data is either related to terrorist activity or child pornography). The crazy thing about the TSA: I flew back from SFO to London last month. I had three laptops in my carry-on bag. I also had a can of Red Bull. Apparently, the can of Red Bull is highly suspicious, but the three laptops are not. I had a perfect excuse though: one was running OS X, another was running Linux and the last was running XP.
