pdfcrypt allows you to set permissions on a PDF file. For example, you can publish a document without permitting users to print it. The button to print the file will be disabled in the Acrobat Reader application. It can be used as a batch application to set permissions on a large group of PDF files, or as a filter in a Unix pipeline, or within a CGI application. Only binary executables are distributed, but the original Perl source code may be requested.
