GnuPG 1.4.23 is part of GnuPG-Pack with old but convincing GPGrelay included, which needs older version 1.4x. http://www.rose-indorf.de/gnupgpack/ Exporting (older) RSA keys should be independent from GnuPG version 1.4x or 2.2x, isn't it? Importing those keys are working faultless with: Flipdog CryptoPlugin/ Android-8.1: https://i.imgur.com/TmR3oiz.png and OpenKeychain/ Android-8.1 too: https://i.imgur.com/vYa1pUl.png Expiration dates of key and 3 subkeys are correct set to 31.12.2019! Only importing with R2mail2/ Android-8.1 causes described expiration error. In my opinion it depends on key structure (1 main key, 3 subkeys for S/A/E)!? If using a 'normal' key with 1 main key S/C/A and 1 subkey for E, importing to R2mail2 works, even if expiration date has been enhanced. Any hint how to bypass this issue? Thx + regards. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
