在PHP中使用PGP加密文件，GnuPG版本意外

Question

I am using gnupg in php to encrypt content.

In a dev environment, encrypted messages begin with:

-----BEGIN PGP MESSAGE----- Version: GnuPG v2.0.22 (GNU/Linux)

For the production environment, encrypted messages begin with:

-----BEGIN PGP MESSAGE----- Version: GnuPG v1

I am at a loss as to why the files are being encrypted differently. Both are valid encryptions, but they decrypt differently (per the recipient, the "GnuPG v2.0.22 (GNU/Linux)" version keeps the file name on decrypt while the other one does not, which is causing an issue on their end).

The following appear to be the same between dev and prod: gpg.conf file, php version, pear version, gpg version, CentOS - version. For the keys, I copied over the .gpg directory from dev to prod (permissioning is the same).

How can I get the prod server to use v2.0.22 of GnuPG on the encryption?

THANK YOU!

Copied over /usr/lib64/php/modules/gnupg.so from the dev machine and this worked in prod as expected. Per the SA, there was a compilation issue due to permissions.
