"There is a First Amendment right to speak in a encrypted way...The right to speak P.G.P. is like the right to speak Navajo. The Government has no particular right to prevent you from speaking in a technical manner even if it is inconvenient for them to understand." « Eben Moglen, Columbia U. professor of law and legal history, in a _New_York_Times_ article by John Markoff, Sep. 21, 1993 »
