Self Incrimination

[Ian BROWN]

Greg Sergienko has a long examination of this issue at
http://www.richmond.edu/jolt/v2i1/sergienko.html

His conclusions were that:

* written-down passphrases have absolutely no protection

* passphrases in your head are likely protected, as disclosing them provides a 
link between you and potentially incriminating ciphertext just as clearly as
giving the police the location of a buried murder victim

He then goes on to describe the sad decline in the protection of private 
papers during the 20th century due to successive Supreme Court judgements.

Unfortunately, as I remember reading his paper, it is all US-law 
jurisprudence. There are very few references to relevant English law prior
to the founding of the US, even if it was still applicable here now.
