define Package/gnupg2/description
GnuPG is a complete and free implementation of the OpenPGP standard as
defined by RFC4880 (also known as PGP). GnuPG allows you to encrypt and
sign your data and communications; it features a versatile key
management system, along with access modules for all kinds of public
key directories. GnuPG, also known as GPG, is a command line tool with
features for easy integration with other applications. A wealth of
frontend applications and libraries are available. GnuPG also provides
support for S/MIME and Secure Shell (ssh). 
endef

define Package/gpgv2/description
 GPGv is a stripped down version of GnuPG that only checks signatures.
endef

define Package/gnupg2-dirmngr/description
Since version 2.1 of GnuPG, 'dirmngr' takes care of accessing the
OpenPGP keyservers.  As with previous versions it is also used as a
server for managing and downloading certificate revocation lists (CRLs)
for X.509 certificates, downloading X.509 certificates, and providing
access to OCSP providers.  Dirmngr is invoked internally by 'gpg',
'gpgsm', or via the 'gpg-connect-agent' tool.
endef

define Package/gnupg2-utils/description

 This package is needed to import keys from a keyserver.
