How to open encrypted PDF files

The PDF specification includes support for AES-128 and AES-256 bit encryption. Compliant PDF viewers are able to decrypt .pdf files that have been encrypted. Strong encryption makes the PDF format a practical way to protected important documetns and files. The PDF Postman add-in for Microsoft Outlook leverages PDF encryption and lets you easily convert your important email messages into an encrypted PDF document that virtually any anyone can decrypt on any device or platform.

The process of opening opening an encrypted PDF file is easy. The recipient only needs to click on the file. If a PDF viewer is present on the device it will prompt the recipient for a password. If the recipient does not have a .pdf viewer, they can easily obtain one from their favorite app store, usually for free.

To experience the process yourself using the PDF viewer present on your device right now, download this sample encrypted PDF file that was created by PDF Postman.
