However for me plausible deniability is not that important. Living in Europe in a country that has ratified the European Charter of Human Rights I have basic freedoms granted to me among the right to remain silent without facing any negative consequence (well, this only plays a role in criminal proceedings).

Right. However, you should know that many countries in Europe have circumvected this. I am sure for France, and the judge who teached us that told us it was copied from other European countries (which I do not remember).

 The idea is that, as you cannot be forced to reveal your password (because you cannot be forced to incriminate yourself) two laws are done for each IT-related felony. For example up to 2 years of prison if data is unencrypted and up to 5 if the data is encrypted. They offer you to be charged with the lesser one if you decrypt it yourself.

 The basic idea is that having encrypted the data probably indicates you knew the data was illegal (which is outrageous !). This is one of the terrible drifts law has followed on IT in the last years. Just as being blamed because someone uses a software you have done (e.g. P2P sharing) for something illegal (DRM violation). It is as if a knife-maker was accused of the crimes done with his knives !!!

Thank you in any case for your HOWTO!
