After further investigation: Actual version of 'Symantec Encryption Desktop 10.2.3' (former known as PGP...) is supporting subkeys for signing or encryption in both directions, accurate interaction with GPG-2.0.26/GPG-1.4.18.
NOT working with subkeys for signing or encryption are: PGP-6.5.1 / 6.5.1ckt PGP-8.1 (thanks to Symantec support...) I did try to get old version of PGP-9.0x, -9.5x, -10.0x, but it seems to be impossible to get it even from Symantec enterprise support. Didn't find it in download archives. Maybe someone can help from private trial archive (email...)? So finally there is still this open question: How is the collaboration between actual branches of GPG-2.0/GPG-1.4 and PGP versions: 9.0x 9.5x 10.0x? Before generating new series of long term keysets, what do you think about this keystructure: Example-keystructure: pub 4096R/97CA9679 erzeugt: 2014-11-22 verfällt: niemals Aufruf: C Vertrauen: uneingeschränkt Gültigkeit: uneingeschränkt sub 4096R/9D22119A erzeugt: 2014-11-22 verfällt: 2016-11-21 Aufruf: A sub 4096R/884627F6 erzeugt: 2014-11-22 verfällt: 2016-11-21 Aufruf: E sub 3072D/37F05D01 erzeugt: 2014-11-22 verfällt: 2016-11-21 Aufruf: S [ unbek.] (1). vorname nachname (kommentar) <n...@edu.com> Thanks and regards, Chris _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
