I'd love to test and patch, but the latest GnuPG release is 2.0.21 and I can't find mentions of 2.1 on their website. 2.0.20 doesn't have the --pinentry-mode option by default (tested in Gentoo). I assume this is the relevant commit that introduces it: http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=21feecd48f990b2569cb4b385dea3e57b9501525 It seems that GnuPG has to be explicitly compiled with --allow-loopback-pinentry which IMO is a really painful requirement to pass onto Emacs users. I am surprised by this, but perhaps I've misunderstood something? Ted
