The prefs associated with your key, is advertising to the sender what you would prefer. However the capabilities to decode an encrypted version is really determined by your gpg version and what ciphers it was associated with. Unless you force an algorithm -- with the cipher-algo preference, if your personal-preference list and the preferences associated with the public key (showpref or pref) have no matches in common (this is not a union of the sets), then 3DES is chosen by default. I believe all gnupg version since inception have had the capablities to decode 3DES encrypted messages as dictated by the OpenPGP RFC specifications. (I could be wrong on this very last statement). The use of personal-cipher-preferences rather than cipher-algo is preferred, since it prevents the problem of sending an encrypted communication that the recipient can not decode. If there is a null union of the personal-cipher-preferences and the key preferences, then 3DES is chosen. -- Kevin Hilton _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
