Slackware 14.0 GPG-KEY
 
Im happy we are almost there for a new version, but...

Wouldn't it be better if we had a renewed/new GPG-KEY to sign Slackware 14.0 packages?

** The current GPG-KEY is from 2003 and will expire on 21st december 2012 **

I know that many people thinks the world is gonna end around this time, but... I'm pretty sure Slackware is going to survive this impending doom, so...

Of course Slackware will survive the apocalypse, as will all slackers. Bob will protect us, and we will party on.

Somewhat related to that end-of-the-world thing... Slackware 14 will have an easter egg which only becomes visible if you install Slackware 14 on 21 december, 2012...

What? Sends a signal via the intertubeswebnet thingy to detonate the entire world's nuclear arsenal? That will be worth seeing. Can't wait. :D

Updated my journal, I'll definitely try that.

It reminds me one fortune cookie: "The world will end in 5 minutes. Please log out." It would be nice to hack fortunes to schedule that one for December 21 :)

H_TeXMeX_H 08-27-2012 09:14 AM

I have to remember to try it.

If you need to update Slackware's GPG key, run

# slackpkg update gpg

The GPG key doesn't change. This should be a "one time" command - run it once and forget it...
So, is that true? or in december we must re-run slackpkg update gpg?

Zerouno,
All digital certificates expire after a certain date. This is because the technology to pose security risks to them can improve a lot between "computer generations".
The current GPG-KEY used by Slackware was issued on february, 2003. That one will expire on 21 december this year. This can be verified using the following command in a bash prompt: gpg --list-keys.

I made a "time change" test in a virtual machine with slack 13.37 and tried to verify a patch signature. It was ok, with return code
0 but also displayed a note saying "This key has expired!".

The question is: will Slackware-14 release a new GPG-KEY, so that all packages are signed with that "future-proof" certificate or will we stick with the current one?
Sticking with a 9 year old key a few months from expiration is at least strange for such a traditional secure distro, IMHO.

But I'm pretty sure Pat will answer us very soon :-)

The patches released in 2013 for slackware 13.37, which gpg-key will use?

Good question!

If the GPG-KEY remains the same, after december 21st, it'll be impossible to sign anything with it. But it will be still possible to verify the old signatures.
I'm not a gpg especialist, but I'm sure there's a decent solution to that problem, maybe using subkeys.

re-sign all old-packages with a new gpg-key :-)




Slackware 8.1 packages are marked in the year 2002. The key presents on the repository is marked 2003.
Which key was used to sign, and when?

Some patch are marked in 2002 and some patch 2012. Are they signed with the same key?

Fortunately slackware 8.1 is End-Of-Life, so it will not soffer the Maya-bug :-)



Edit:
On the original cd of slackware 8.1 (that is downloadable) there is no gpg-key, and packages was not signed.
This means that the original packages was signed in future.

Well. This means that the 13.37 and all not EOL slackware will must be re-signed with a new key.

If a GPG key's expiry date is updated, then files which were signed with the old version of the GPG key will still validate OK.
I'll let you in on a secret:
Code:

$ gpg --refresh-keys
$ gpg --list-keys "Slackware Linux Project"
pub  1024D/40102233 2003-02-26 [expires: 2038-01-19]
uid                  Slackware Linux Project <security@slackware.com>
sub  1024g/4E523569 2003-02-26 [expires: 2038-01-19]
$ gpg --verify ~ftp/pub/Linux/Slackware/slackware-13.37/CHECKSUMS.md5.asc
gpg: Signature made Mon 25 Apr 2011 04:56:55 PM CEST using DSA key ID 40102233
gpg: Good signature from "Slackware Linux Project <security@slackware.com>"

Thank you Pat and Eric!
Ive just noticed Slackware 14.0 RC4 included the updated GPG-KEY.

So...
Maya BUG: Bye, bye!
Year-2038 bug: Well squash you at the right moment ;-D

Aak! I don't have access to my laptop today to reinstall Slackware 14.0! I won't see the Easter Egg! 'Tis the end of the world! :'(
I'm going to hazard a guess and say that the Easter Egg is a Mayan themed Lilo boot screen... even though I dreamt (can you believe it!) a while ago that the first boot would flash ASCII keys (yes, the ones that open doors) in place of the ASCII... things that appear during first boot. But I'm probably incorrect on both fronts. Has anyone seen the Easter Egg?
