A few months ago I posted statistics of the types of digital signatures used on Usenet and in mailings lists. It turns out that the moderators' signatures in a moderated newsgroup were tabulated for the individual posters, resulting in somewhat too big figures for one particular version of PGP. Here are the current figures: 56.6% PGP 2.* 33.7% PGP 5.* 3.6% other OpenPGP implementations 4.0% S/MIME The sample contains 249 unique (e-mail address, software version) pairs taken from various international and local newsgroups and mailing lists that happen to be available in my news spool (consisting of some 24,000 articles). Perhaps someone with a full newsfeed -- whatever that is in these days -- would like to try the same? These are the PGP Version headers: 55 2.6.2 24 2.6.3i 19 2.6.3ia 17 PGPfreeware 5.5.3i for non-commercial use <http://www.pgpi.com> 15 2.6.3in 14 PGP for Personal Privacy 5.0 10 PGP for Personal Privacy 5.5.3 9 2.6.3a 8 PGPfreeware 5.0i for non-commercial use 7 PGP 5.5.5 6 2.6.2i 4 PGP for Personal Privacy 5.5.5 4 2.6.3a-sha1 3 PGP for Personal Privacy 5.0.1iRu 3 PGP for Business Security 5.5 3 2.6.3 2 PGPfreeware 5.5.5 for non-commercial use <http://www.nai.com> 2 PGPfreeware 5.5.3i for non-commercial use 2 PGP for Business Security 5.5.6 2 PGP for Business Security 5.5.2 2 PGP Cyber-Knights Templar build 5.5.3ckt 2 GNUPG v0.3.1 (GNU/Linux) 2 GNUPG v0.3.0 (GNU/Linux) 2 CTCDOS 0.1 1 Version 2.0.0 1 PGPfreeware 5.5.3i for non-commercial use 1 PGPfreeware 5.5.3 for non-commercial use <http://www.pgp.com> 1 PGPfreeware 5.5.2 for non-commercial use <http://www.pgp.com> 1 PGPfreeware 5.0 for non-commercial use <http://www.pgp.com> 1 PGP for Personal Privacy 5.5 1 PGP 5.5.3 It's not only for cool looking messages! 1 PGP 5.0i 1 PGP 5.0 1 GNUPG v0.3.2a (GNU/Linux) 1 GNUPG v0.3.2 (GNU/Linux) 1 GNUPG v0.3.1a (GNU/Linux) 1 4.0 Business Edition 1 2.7.1 1 2.7 1 2.6.i 1 2.6.3uin 1 2.6.1 1 2.6
