In what country is there actually a "right to private, encrypted communication"? At best there's rights for "privacy", which is a pretty woolly concept, but generally don't cover copyright infringement. More to the point, unless you reject the concept of copyright entirely, you have to accept that free speech rights will have to be "violated" to enforce it.
I recognize that this is not a popular opinion, but IMHO IT SHOULD BE covered by the "secure in their papers" section in the 4th Amendment in the US, and/or with established precedent regulating encryption export as armaments, by the 2nd & the Heller decision granting the rights afforded by the 2nd to the individual
at least that's the correct interpretation of the founding document as far as I can tell. not that it matters anymore.
