Hi cuttenweiler, I haven't used GnuPG myself, but the docs state: The API is accessed through methods on a GnuPG object which is a wrapper around the gpg* program.* ... whereas you apparently have `gpg2`? Maybe this helps. The way forward always starts with a minimal test.	[reply] [d/l]

Indeed - gpg2 is installed and operating correctly. When I run all of the tests in the test.pl from the command line using the native tools, I succeed. (Get key, encode, decode, import, export, etc etc.)	[reply]

"gpg2 is installed and operating correctly" ... whereas the docs for GnuPG begin with: `GnuPG - Perl module interface to the GNU Privacy Guard (v1.x.x series)` [download] The way forward always starts with a minimal test.	[reply] [d/l]

PS -> GnuPG does work with gpg2. Verified on a Gentoo box, and a few other distros. Am I the only guy working with the GnuPG module on CentOS 7? 'Cause I just tested it with a fresh out of the box CentOS 7 image and Vendor perl (5.16.3) and it fails the exact same way as 5.20.2. Severe weirdness!	[reply]

This might be the same as RT 117002 and/or the test failures to which it refers. So I'm working with Perl 2.20.2 I assume here that should be 5.20.2. If you aren't using the stock CentOS7 perl (5.16.3), why install such an old one? Or are you using an update/respin of CentOS7?	[reply]

Typo's make life more interesting... yes indeed it's 5.20.2. I'm locked into that at the moment because of a very very large confederated perl legacy application that uses / is verified on that version. I'm using perlbrew to overlay the vendor perl. I've verified my paths and libs are correct. I also reverted back to vendor perl and still have the same issue. I'm about to launch a fresh CentOS 7 and try to install the module there to see if there is something about perlbrew that could be causing the issue. I don't have high hopes for that... but we'll see.	[reply]

Looks like this was addressed on Debian by forcing the module to use GPG1, perhaps other distros have done the same? https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=834522 Perhaps try setting gnupg_path to point to GPG1 binary and see if that works.	[reply]
