PDF Postman, An Alternative To Traditional Outlook Email Encryption Solutions

PDF Postman is the add-on for Microsoft Outlook 2013/2010/2007/2003 that secures your email message using the PDF frmat.  It's an alternative to traditional email encryption software schemes intended to simplify the sending of sensitive messages and files for the recipient.  PDF Postman is a good solution where the sender needs to deliver documents or a message by email, but does not need to receive a reply from the recipient.

PDF Postman leverages the Advanced Encryption Standard (AES) encryption that is part of the PDF format.  It supports encryption strengths of 256 bits or 128 bits.  Since compliant PDF viewers are available across all platforms, from Windows, Linux, Mac, Android, iOS, Blackberry, etc., the recipient of a PDF Postman encrypted message need only know the password.

The process for the recipient is simple. They click on the encrypted PDF file, and it opens in their local PDF viewer. The recipient's PDF viewer detects the encryption and asks for a password. If the password is correct, the PDF message and file attachments are displayed. If the password is correct, the message is displayed. The same password to encrypt the file is used to unencrypt it. This is called symmetric key encryption.
