gpg2 is the OpenPGP part of the GNU Privacy Guard (GnuPG). It

You only need to use GnuPG 1.x if your platform doesn’t support GnuPG 2.x, or you need support for some features that GnuPG 2.x has deprecated, e.g., decrypting data created with PGP-2 keys.
In contrast to the standalone command
gpg from GnuPG 1.x,
the 2.x version is commonly installed under the name
