Encrypting PDF files with 256bit AES protection by EEPDF PDF Security

Use PDF Encryption Software to Encrypt PDF Files & Documents

Why would I want to encrypt PDF documents (PDF encrypt)?

There are many reasons why you would want to use PDF encryption. The information in the PDF document is confidential and only a restricted number of people should be able to see it. This could include training courses, price lists, bid documents, takeover plans, healthcare records, and so on. The information is valuable – you sell it – perhaps a newsletter, or an analyst's report, or a consulting report or a periodical or a book. You obviously don't want to give it away!

If you don't encrypt the PDF file then anyone can read it and the value of your information is lost.  But if you are going to encrypt PDF files you need to select a package using a reliable encryption method.

How does PDF encryption differ from PDF Security or PDF Digital Rights Management controls?

Well, PDF encryption prevents those who are not authorized from using the PDF document.  But those who are authorized to use it can decrypt it and then do whatever they wish with it – copy it, send it to friends, edit it, print it and so on.  In some instances, such as transferring financial data for computer processing, encryption on its own provides all the requirements.  But information in published documents such as the ones we listed above means you need additional controls to actively prevent a user who is authorized to see the document from doing other things that you do not want to approve.
