Welcome! And your question is not trivial. The following is the procedure I use on UNIX systems: First, export all public certificates into a public keyring: $ gpg --armor --export > pub.asc Second, export all secret certificates into a secret keyring: $ gpg --armor --export-secret-keys > priv.asc Third, export ownertrust values and save those: $ gpg --armor --export-ownertrust > trust.asc Fourth, copy all the *.conf files in ~/.gnupg into your current directory: $ cp ~/.gnupg/*.conf . Fifth, put these, and all your GnuPG .conf files, all into a single archive: $ tar cJf gpg-backup.txz pub.asc priv.asc trust.asc *.conf Copy gpg-backup.txz to the new machine. Once you've done that, uncompress it on the new machine: $ tar xJf gpg-backup.txz Import your secret certificates: $ gpg --import < priv.asc Import your public certificates: $ gpg --import < pub.asc Import your ownertrust values: $ gpg --import-ownertrust < trust.asc Make sure your ~/.gnupg directory exists. If it doesn't, run gpg with no arguments and hit Ctrl-C to break out of it. $ gpg Copy your .conf files into ~/.gnupg: $ cp *.conf ~/.gnupg ... And at that point you should be done. This technique should work regardless of whether you're migrating from 1.4 to 2.0, 1.4 to 2.1, 2.0 to 1.4, 2.0 to 2.1, 2.1 to 2.0, or 2.1 to 1.4. No matter which you're doing, you're covered. > I've just copied my .gnupg directory to a usb key as a backup measure, which > I found as a method (more or less) on > http://www.glump.net/content/gpg_intro/. It's a good idea to not copy the random_seed file. PRNG states should not be shared between computers. > How can I make sure my private key and trust assignments were copied properly? Follow the above process and they will be. Your private certificates were exported, as were the trust assignments. > Once I have completed my OS upgrade how do I restore my keys and the > trust levels assigned to them? See the above process. > I use Thunderbird/Enigmail which is using gpg2 but I originally created my key > pair using gpg 1.4. Does this have any ramifications? None. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
