These sorts of techniques make great comments, but are nearly useless in reality. First of all, even if you're being truthful, saying "I don't know my password" will likely not be believed. Explaining the process you went through to safeguard your password will merely elicit suspicion by a border agent. Why would you go through such pains if you had nothing to hide? And once they are suspicious of you, you will almost surely be detained and have your equipment seized. Yes, the government might not be able to decrypt it for years, but they still have your laptop, and they are still in possession of your data, encrypted as it may be. So, I ask you, who won this little battle? It sure wasn't you. IMHO, the only valid approach here is to host everything on an external server, and VPN / SSH into it to do your work. Don't store the connection info locally, and don't store any passwords / keys locally. Make sure no confidential files ever touch your hard drive, even in a cache. Most agents have no idea how that process works, and unless you have a shortcut on your desktop / home directory labeled "connect to home fileserver" they probably won't even think to ask you for any further info. EDIT: Stupid spelling error. Thanks, recursive.
