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.

  1. install Enigmail
Thunderbird > Add-ons Menu > Enigmail
  1. If 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 Management
  1. In the Key Management window, select
File > Import Keys from File

and 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!

Go to Enigmail > Key Management.</p> <p>In Key Management window, go to File > Import Keys from File.</p><p>You gnupg folder is in /home/$USER/.gnupg, so point to that directory and Enigmail figures out the rest. I just tested it and it told me that the key already had been added to Enigmail; ignore that message. As long as you see your key listed in Key Management, you should now be ready to go. – Klaatu von Schlacker Feb 3 '15 at 23:03
  • You should not run gpg --gen-key as root. You are generating a key for yourself as a user, not as root. – Klaatu von Schlacker Feb 3 '15 at 23:07

You can just install gnupg2 (2.0.22) from thebase` repo, but chances are that it is already installed (as it was on my CentOS system).
