Secure PDF Viewer Sample

The Aloaha Secure PDF Viewer is a project to demonstrate the broad functionaly of the Aloaha PDF Form Saver OCX.

PDF suffers of one big limitation. It is not easy to control if a user can save a PDF document locally. First of all most PDF Viewer have a save option as such and secondly most of them cache the PDF in the Window temp folder. Even the traffic between the server and the PDF Viewer could easily sniffed and used to rebuild the secret PDF document.


The Aloaha PDF Viewer is based on the Aloaha PDF Saver OCX. This OCX is included in our Aloaha PDF Saver and Aloaha PDF Signator. To be able use the Aloaha Secure PDF Viewer either the PDF Saver or the PDF Signator has to be installed.

Since viewing of PDF Documents is a freeware feature of the Aloaha PDF OCX no license key is required to use the Aloaha Secure PDF Viewer.

Usage of Secure PDF Viewer

The usuage of the Aloaha Secure PDF Viewer is pretty straight forward. Just use as an commandline option the file to be opened.

For example:

c:\> "Secure PDF Viewer.exe" http://www.aloaha.com/download/test.pdf

or

c:\> "Secure PDF Viewer.exe" MyPDFDocument.pdf

It is also possible to load a PDF directly from a memory location. This is usefull if a PDF should be retrieved/transported encrypted. A decryptor could store the decrypted document somewhere in Memory and instruct Aloaha to load the document from there. 

How this is being done is demontrated in the sourcecode.
