Comments

The Low Level encryption method (40-bit RC4), allows access for some PDF document areas to be restricted. If set, the user may allow/disallow the following features of the created PDF document: print document, modify document content, extract text and graphics, modify comments, etc.

The High Level Encryption method (128-bit RC4), allows for more restrictions than those of the low level encryption method. They include such options as whether high resolution printing and document assembly are allowed.
