425e2dcd66 Add client code back in 
Client code basis back in, parsing of command line options as well.
Client does not do anything yet, though.

9ea0a9695c Fix bug with commandline parsing 
For each parameter, all previous parameters were overwritten with
default values. Fixed.

2143adc91f Added detached thread handling code 
Make it easier to create a detached thread, it's always the same and
error-checking is quite repetitive.

8200c9668d Rewrite README 
A lot has changed, let's update the README even though it's not all done
yet.

luksrku server.

603e63876f Server implementation seems to work 
Rudimentary functionality of server (not including responding to
announcements over UDP) is working now.

3e5c7d541c Implement actual lookup of luksrku entry 
Now with a proper UUID the PSK is looked up from the key database.

d70bd1f672 TLS-PSK connection is working in TLSv1.3 
Apparently, I need to spell out "-ciphersuites
TLS_CHACHA20_POLY1305_SHA256:TLS_AES_256_GCM_SHA384" in the openssl
s_client command, or it simply will not work.

969eae12c7 Started with server implementation 
Running into issues with TLSv1.3-PSK. Connection establishment does not
work at the moment.

667ff55af1 Integrate editor properly from command line 
Now have a way to invoke the editor functionality from the command line
and also provisions to include the server and client parsers.

ecbf3827ca Integrate current state-of-affairs into luksrku 
Now integrated into the official Makefile. All functionality is broken
(was for a while), but it's progress nevertheless.

20ffe38b53 Implemented export of key database 
Key database is exported on a client-per-client basis, but with
sanitized LUKS passphrases of course. This is implemented now.

722476e7fd Implemented more useful commands 
Implemented add/delete operations of hosts and volumes and rekeying of
both as well.

0cb0e5d470 Further work in keydb 
Work in transcribing the binary LUKS PSK to ASCII. Still buggy, had an
error in thinking (it's not 4 bytes transcribed to 3, but 3 to 4 of
course). Needs fixing.

bcd794a6c1 Further work on creating correct type-4 UUIDs 
Have the UUIDs actually look and feel like Type-4 UUIDs according to
RFC.

ffca14559f Further work on UUIDs and the interactive editor

68c74de050 Saving and loading of key database works

9c888cbe4e Major rework of keydb and file encryption 
Currently, main program does not compile, massive rework of the internal
database storage mechanism to allow integration of vault and online
editing.

b79ae0b417 Initial work on providing an editor 
Just laid out the framework for online editing of the key database,
which was just horrible before.

1790275960 Release v0.02 
If this release ever makes it to a disto, we want to be able to identify
it by version number, not by commit. Therefore, introduce re-release
with proper tagging.
 2019-10-19 15:08:30 +02:00
Johannes Bauer
73ab437fc9 Include tags in released version number 
We want the displayed version number to contain tags, so add it to the
Makefile option.

f824198abd Release v0.01 
First release after three years of daily use seems a justified testing
period.

363fc70f1c Use pkg-config and have git-based version number 
Use pkg-config to find OpenSSL headers and library. Use "git describe"
to determine current version.

d8208fbab5 Make vault iteration count adaptible to hardware 
We want to specify a real time for key derivation and let it figure out
by itself how many iterations it needs.

1312bce9af Add license header to vault files 
Since this was just work-in-progress, I had forgotten to include license
header text.

aa9fa3e995 Started working on a coldboot-resistant "vault" implementation 
When not needed, encrypt the keys in-memory with a large pre-key so that
forensic acquisition of data using coldboot becomes infeasible. Not used
yet internally.

2cde43d357 Fix issue with TLSv1.3 negotiation 
TLSv1.3 behaves differently in how PSK identity/PSK identity hints are
exchanged, at least in regards to OpenSSL. This caused the TLS client to
not send their TLS identity to the server, which rejected the connection
(it expected "luksrku v1"). Couldn't solve it with TLSv1.3, so we're now
simply forcing TLSv1.2.

1c61480b71 Show log output even in verbose mode 
Compiling with -DDEBUG isn't required to show output of commands,
verbose mode is sufficient.

bc291dcbd8 Change stupid debug message and output more debug info 
When compiled in debug mode, output more info. Also change the insanely
stupid "exited successfully" message to something actually sensible.

625998fc8a Only execute luksrku when an actual server config is present 
Previously, it was always executed (although it shouldn't have made it
into the image if no /etc/luksrku-server.bin were present).

781b10c0c9 Assume system-wide installed OpenSSL v1.1 
After Debian has pretty much migrated to v1.1, we now assume that
OpenSSL is preinstalled system-wide -- it's not experimental anymore.
Currently we assume it's preinstalled in /usr/local.

b8659ae8fc More README.md fixes 
Mixing terminal output and lists isn't apparently well supported (or I
cannot figure out how to do it). Change text a bit as a workaround.

8b892e3347 Update OpenSSL version and change sig algs 
While the PSK cipher suites do not use any ECDHE/RSA signatures, in the
future someone may change the code. In that case, as a robustness
measure, already set the acceptable signature algorithms now.
Additionally upgrade to OpenSSL v1.1.0e and include the comment to
include X448 once it becomes available for TLS ECDHE (it's not yet,
unfortunately).

58a73a552f Try to use initramfs IP autoconfig 
Trying to get rid of the current (shitty) manual IP configuration
process. This should enable you to specify on the kernel command line a
parameter like ip=:::::eth0:dhcp and the initramfs scripts would take
care of acquiring a DHCP address instead of static configuration in the
script itself.

6089d98721 Introduce --max-bcast-errs command line option 
This enables luksrku to terminate if a certain number of broadcast
attempts has failed (usually due to unavailable networking), therefore
enabling a second method of unlocking LUKS disks (e.g., by manually
entering the password on the console).

0d4d2220b2 Implemented unlock cnt and blacklist 
Can now unlock a specified number of hosts as specified on the command
line (e.g., if you want a luksrku client run indefinitely) and also used
the already implemented blacklisting functionality (i.e., if an
unlocking is unsuccessful, it is retried in 120 seconds, not
immediately, as not to spam servers with illegal credentials).
