We all need to be cypherpunks now

Hello dear reader, please take a look at the text below:

What has just landed in your computer is a block of cyphertext encrypted using a Serpent serpent, 256-bit key, 128 bit block cypher with a RIPEMD-160 hash.

And you do not know the decryption key.

So, as of this Monday just gone, when PC Plod comes round to your house and finds this on your computer and demands you decrypt it and you say you can't because you don't have the key then that is no longer a defence and you can get two years in the nick. Welcome to the Regulation of Investigatory Powers Act 2007 and the overturning of the principle of innocent until proven guilty. Also remember that you are deemed to have "made" that piece of cyphertext too because having downloaded it, albeit unwittingly when you opened my blog on your browser, you have made a copy and that counts as "making" - you know all those people they get for child porn and they get done for x counts of "making images" that's what it means, it doesn't mean they got their cameras out.

Ihr papieren ist nicht in ordnung. Kommen Sie bitte mit uns.

So what to do. Well you could do worse than get yourself a copy of TrueCrypt which is a free, open source encryption utility that's really easy to use and has one killer feature that'll keep you safe from Brown's Geheime Staatspolitzei. What it does is you can tell it to create an encrypted disk drive within an encrypted disk drive; that way you can have an encrypted drive with a key you can reveal to the plod in which all they see is a bunch of files with your bank details and other mundane stuff in them that any normal, prudent citizen would want to keep safe in the event of their PC being stolen. However hidden on that drive is the second secure drive that unless you type in the right passwords doesn't even appear to be there, nor is it possible to prove their is a second drive and of course it is on this second drive that you store all your bomb making instructions, plans for setting fire to the Labour front bench and of course your dragon porn.

I've been using it for a couple of days now and it's supplanted my previous software (DriveCrypt) as hiding things tool of choice. Go get a copy, even if you have nothing to hide (but trust me that you do), just to stick two fingers up at the fascists we call a government
