Back in October, LWN reported on a talkabout thestate of the GNU Privacy Guard (GnuPG)project, an asymmetric public-key encryption and signing tool that had been almost abandoned by its lead developer due to lackof resources before receiving a significant infusion of funding and communityattention. GnuPG 2 has brought about a number of changes andimprovements but, at the same time, several efforts are underway to significantly change the wayGnuPG and OpenPGP are used. This article will look at the currentstate of GnuPG and the OpenPGP web of trust, as compared to new implementationsof the OpenPGP standard and other trust systems.
