Pretty Good Privacy (PGP) is a computer program that provides cryptographic privacy and authentication.
PGP is often used for signing, encrypting and decrypting e-mails to increase the security of e-mail communications.
It was created by Philip Zimmermann in 1991.

The use of PGP in file exchanges has increased over the years and has become a common way of securing file contents. Thus, encountering use of PGP in projects has become more common as well.

There are several implementations for popular platforms such as Java and .net; however the availability of easy to implement PGP solutions for ColdFusion is limited. In particular, I found existing implementation rather difficult to use.
Thus, I embarked on this project. To make a long story short, I ended up using the underlying work of the league of bouncy castle (bouncycastle.org) folks. The complete source code for those libraries can be downloaded from there.

I am packaging this in an installer for Windows as the installation is slightly more complex than I would like. There are instructions for manual installation if you do not use Windows OS or want to do this yourself.

Sample code should show most common operations. I have not exposed all areas of PGP. This may come in future versions as I have time or demand is there.

Updated underlying libraries to latest release.
Added support for Unicode filenames.
Added support for Single Pass Signed file creation.
Improved Examples and made them easier to use.
Improved release of file resources.
To upgrade uninstall (remove jars), and install (copy) new jars. Or use installer.

This has been tested for CF 8,CF 9 and Railo 3.x
You can use the PGP libraries in Flex as well if you backend it with ColdFusion.
Simply change the Access Modifier of the functions in the main controller cfc.
