EVO PDF Security Library
The EVO PDF security for .NET can be used in any type of application to manage the security settings of the PDF documents. You can encrypt the PDF content, add user and owner passwords, control the PDF document permissions for printing, copying, assembling, filling forms, editing content, editing annotations, etc or you can specify the length of the encryption key to 40 or 128 bits, remove all the security settings by providing the user or owner password. If you need a simple ready to use tool for combining your PDF documents and images we offer you a command line utility. The integration is extremely easy and no additional installation is necessary in order to get started. It's just a .NET assembly that you have to reference in your application.
