I just want to announce a thing that the Mobility Project has been making: it's a special security toolkit with GnuPG, built-in support for TIGER192, support for IDEA encryption through IDEA.DLL, and technology from GPG2GO allowing everything to work from any location (and leave not trace in the Windows registry). Basically, it's a mobile security toolkit supporting virtually every hashing and encryption format you're likely to need.
IdeaTiger is designed to be the encryption toolkit for Mobility Email, our forthcoming email client distribution. However, it's able to work on its own (on my own machine I use it instead of the standard GnuPG distribution).
I'd love to hear your thoughts on the toolkit, and suggestions about how to improve it.
