It is an  ENCRYPTED PDF document, which means the only  thing i can do
with it is use adobe's software to view it. I can not cut and paste. I
can not extract the text from  its layout. I can only search and index
it through  their clumsy software. I  can not pipe the  text through a
voice  synthesizer  to read  the  text aloud  to  a  blind friend  or
translate it into braille.

Do not misunderstand  me. i enjoy having an  electronic version of the
text, and i am grateful HUP did it. but it it is not a FREE version of
the text.

There is a  reason why the man who broke this  encryption scheme is in
jail. This  kind of lame  encryption scheme is  the last hope  to turn
bytes into  a commodity. Merchants  need commodity. The  government of
the US is very concerned by the well being of merchants.

i had the feeling they were  collecting the $ through a US company who
discontinued the collaboration after the arrest..i might be wrong

well i won't  ask how you did. my  hope was to be able  to find enough
information in the slides  from defcon, which are available somewhere,
to decrypt the pdf, but since someone already did it...
