The Distributed Privacy Guard (DKGPG) implements Distributed Key
Generation (DKG) and Threshold Cryptography for OpenPGP. The
generated public keys are RFC4880 compatible and can be used by e.g.
GnuPG. The main purpose of this software is distributing power among
multiple parties, eliminating single points of failure, and
increasing the difficulty of side-channel attacks on private key
material.
DKGPG consists of a number of command-line programs. The current implementation
is in experimental state and should NOT be used in production environments.
A shared private key and a common public key (currently only
DSA/ElGamal) are generated. Further interactive protocols perform the
private operations like decryption and signing of files, provided
that a previously defined threshold of parties/devices take part in
the distributed computation. Due to the interactiveness of the
protocols, a lot of messages between participating parties have to be
exchanged in a secure way. GNUnet's mesh-routed CADET srvice is used
to establish private and broadcast channels for this message
exchange. A TCP/IP-based service is included as an alternative. It
may be combined with torsocks and NAT of a local hidden service.

Changelog

2019-04-28 - Karol Babioch <kbabioch@suse.de>
- Update to version 1.1.1:
Some small improvements have been applied for dkg-generate: Two new
options ("-u" and "-N") allow providing the initial user ID and to
disable the passphrase at command line. Moreover, since this release
dkg-timestamp and dkg-timestamp-verify require a special key usage flag
from recent RFC 4880bis draft to select so-called timestamping keys.
Finally, the synchronization time of the internally used broadcast
protocol was reduced to a more reasonable amount and in dkg-decrypt the
detection of end of data for message and decryption shares was changed.
2018-12-10 - atoptsoglou@suse.com
- Update to version 1.1.0:
This release supports Authenticated Encryption with Associated Data (AEAD)
in accordance to RFC 4880bis (draft); this can be enforced with the new
added option "-a" when  dkg-(d)encrypt is used. For using domain parameters,
as described in RFC 7919, one should specify the new option "-r", when
dkg-gencrs is used. Last, for key generation (dkg-generate) the timestamp
option was added ( "--timestamping") which sets a key usage flag.
2018-11-12 - Karol Babioch <kbabioch@suse.com>
- Update to version 1.0.9
This release improves the possibilities of DKGPG further. With the new
programs dkg-adduid and dkg-revuid an user ID can be added and revoked,
respectively. The program dkg-revoke now supports a human-readable
reason for revocation (by option "-R") and dkg-decrypt verifies an
included signature according to a given key ring (option "-k"). Last
but not least, by the program dkg-addrevoker an external revocation
key can be specified.
2018-09-13 - Karol Babioch <kbabioch@suse.com>
- Update to version 1.0.8:
First of all, passive support for ECDSA, ECDH, and EdDSA (cf. RFC 6637
and Werner Koch's draft RFC 4880bis) has been added by relying on the
most recent version of LibTMCG. The threshold signature scheme and the
threshold encryption are still limited to finite field cryptography
(i.e. DSA and ElGamal). Moreover, the programs generate and recognize
a few other new OpenPGP features (e.g. issuer fingerprint subpackets)
from RFC 4880bis. Compressed messages are now decompressed by the
program dkg-decrypt using zlib Compression Library (and optionally by
library routines from libbzip2). This completes DKGPG's compatibility
with other OpenPGP software, however, the prefered compression algorithm
(i.e. "no compression") in self-signatures of generated keys is kept
for now. Support for symmetric-key decryption by dkg-decrypt has been
added too. The program dkg-verify now reads the signature from a file,
if option "-s" is used. To keep track of later protocol changes, all
interactive programs include a version identifier in their common ID of
the reliable broadcast channel. Thus programs from previous releases
will not communicate with those of this release. With the new programs
dkg-timestamp and dkg-timestamp-verify a OpenPGP timestamp signature
can be generated and verified, respectively. Last but not least, by the
new option "-y" some programs (dkg-generate, dkg-decrypt, dkg-sign,
dkg-keysign, and dkg-timestamp) will work with regular OpenPGP keys too.
The README file contains a configuration sample showing how to replace
classic PGP by DKGPG in the famous mail user agent mutt based on this
option. Please note that this feature is experimental and semantics
may be changed later.
- Added new build requirements:
* zlib
* bzip2
2018-07-09 - kbabioch@suse.com
- Update to 1.0.7:
* Small improvments due to the new OpenPGP structures from libTMCG
* "-k" option has been added to further programs
* OpenPGP cleartext signatures can be generated with the "-t" option
* Output of potentially malicious user IDs has been sanitized in
dkg-keycheck, dkg-keyinfo, and dkg-keysign
- Applied spec-cleaner
