How can I install GnuPG on my CentOS 7 system?  I want to use GnuPG alongside Thunderbird and Enigmail to manage pgp keys, as per the instructions in this link.  The problem is that the download instructions I find for linux all have to do with Debian.  Here is an example.  EDIT typing which gpg resulted in /usr/bin/gpg, however, it is not clear that this is the same aspect of GnuGPG that needs to be integrated with Thunderbird and Enigmail to manage gpg keys.  Before this question can be considered answered, I need to know that GnuPG is installed in a way that can run with Thunderbird and Enigmail.  Thus, the answer would give instructions for checking status, and instructions for downloading if it is not properly installed yet.  I imagine this might only take several lines of actual methods.
installing GnuGPG with Thunderbird on CentOS 7
centos;email;encryption;gpg;thunderbird
install EnigmailThunderbird > Add-ons Menu > EnigmailIf you do not already have a PGP key, generate one:gpg --gen-key(follow its prompts to complete the process; default values are generally fine) 3. Restart Thunderbird. Enigmail will probably auto-detect the presence of your GnuPG keychain and use it. If it does not, point it to your GnuPG dir:Thunderbird > Enigmail > Key ManagementIn the Key Management window, select File > Import Keys from Fileand show Enigmail to your /home/$USER/.gnupg directory. Import your key; ignore errors from Enigmail that it already knew about your key. You should now see your key listed in the Key Management window. 5. Email somebody!
