dirmngr

Description

GNU privacy guard - network certificate management service
dirmngr is a server for managing and downloading OpenPGP and X.509
certificates, as well as updates and status signals related to those
certificates.  For OpenPGP, this means pulling from the public
HKP/HKPS keyservers, or from LDAP servers.  For X.509 this includes
Certificate Revocation Lists (CRLs) and Online Certificate Status
Protocol updates (OCSP).  It is capable of using Tor for network
access.

dirmngr is used for network access by gpg, gpgsm, and dirmngr-client,
among other tools.  Unless this package is installed, the parts of
the GnuPG suite that try to interact with the network will fail.
