DESCRIPTION="An OpenPGP keyserver which is decentralized with highly reliable synchronization"
HOMEPAGE="https://bitbucket.org/skskeyserver/sks-keyserver"
SRC_URI="https://bitbucket.org/skskeyserver/sks-keyserver/downloads/${P}.tgz"
LICENSE="GPL-2"
SLOT="0"
KEYWORDS="~amd64 ~x86"
IUSE="optimize test"
DOC_CONTENTS="To get sks running, first build the database,
start the database, import atleast one key, then
run a cleandb. See the sks man page for more information
Typical DB_CONFIG file and sksconf has been installed
in /var/lib/sks and can be used as templates by renaming
to remove the .typical extension. The DB_CONFIG file has
to be in place before doing the database build, or the BDB
environment has to be manually cleared from both KDB and PTree.
The same applies if you are upgrading to this version with an existing KDB/Ptree,
using another version of BDB than 4.8; you need to clear the environment
using e.g. db4.6_recover -h . and db4.6_checkpoint -1h . in both KDB and PTree
Additionally a sample web interface has been installed as
web.typical in /var/lib/sks that can be used by renaming it to web
Important: It is strongly recommended to set up SKS behind a
reverse proxy. Instructions on properly configuring SKS can be
found at https://bitbucket.org/skskeyserver/sks-keyserver/wiki/Peering"
