RE: This file is protected...


Dov is correct when he says a protected file cannot be re-distilled directly
from a .ps file after printing etc but this is if there is no human
intervention at the .ps stage. The .ps file is just a .txt file per se, so
the blocks of encryption (and there are many of them scattered throughout a
file) can be replaced with an appropriate statement that will then allow the
.ps to be distilled creating an unprotected PDF.

Obviously there are potential ramifications of removing the encryption
without the appropriate permissions (and why someone would give them is
beyond me) but it is technically feasible.
