Earlier this year, the email encryption system known as Pretty Good Privacy was rescued from the nincompoops at Network Associates, and will soon be available from the PGP corporation.
The best news is that we will finally have an OS X-native version. You can try it out now through PGP’s public beta program. Highlights include: Full support for Mac OS X 10.2; full PGP Disk interoperability with PGP Disks created by all prior PGP Disk products for Mac OS, as well as with PGP Disks created with PGP Disk for Windows 7.0 and later; AES (Advanced Encryption Standard) support in PGP Disk; significantly expanded Unicode support; built-in support for Apple Mail and Microsoft Entourage X; PGP encryption and digital signature features are accessible as a Mac OS X service from Cocoa applications and Carbon applications that support services; PGP features are also accessible from the PGP’s Dock menu, providing a second ubiquitous method for accessing PGP.
This may actually get me back into the crypto game. You may very well have to finger me for my public key soon!
