File types used by ArtistScope security
applications include a new type known as
.ENC, which opens in CopySafe PDF Reader.
The .ENC file type is created by CopySafe
PDF Protector when encrypting Adobe PDF
files. It is a library file for viewing with
CopySafe PDF Reader, which may also be
referred to as the CS-PDF Reader.
.ENC files are most useful when publishing a
series of CopySafe protected PDFs because
they do not include the reader, which
reduces the file size by 2 MB.
To deliver .ENC files from a server, you may
need to add ENC to the server's Mimetypes:
.enc application/octet-stream
An ENC file is a generic encrypted file usually of
proprietary encryption origin and encrypted to protect it from unauthorized use.
ENC files may be encoded in the .UUE format, which can be opened with a program
like 7-Zip. However, ENC files
using a proprietary encryption may be opened by the program that was designed to
do so.
