Status of the OpenPGP keyring: 1024D is a thing of the past!

Having seen the end of December and the beginning of January, this is the time of year where we say "Happy new year!"

But this is a very interesting new year: We have also went past our much announced deadline for the <2048 bit keys to be removed from the Debian keyrings. And yes, our highly efficient keyring-maint team managed to deliver on the promised time — And, I'd say, with much success. Lets see the numbers — Only before that, refer to Jonathan's mail to debian-devel-announce for further, fuller information.

So, first of all, how do overall numbers look? Just remember, the following are not the number of DDs, just the number of active keys. That is, the holders to the 252 DD and 35 DM keys we removed are still valid Debian Developers/Maintainers, but have to get a new key accepted to perform many of their tasks in the project.

The graph above shows the sharp change between tags 2014.12.31 and 2015.01.01. But my definition of success is that we managed to get the number down to just 252+35=287 from what we had back in August, when we did our DebConf presentation and started the aggressive push: 490 DD keys and 49 DM keys. Since then, 34 DDs requested their retirement, becoming emeritus, and practically all of the rest managed to get their key transition done!

So, lets go again easiest-to-hardest. First, the Non-uploading Debian Developers keyring:

As this is the newest keyring in existence, and is also the smallest one, we were already without <2048 keys since 2011. Nothing to see, move along.

Then, as for the Debian Maintainers:

We did have a sensible migration from weaker to stronger keys, but it was not as sharp as I'd have liked. That makes sense, after all, since DMs have less involvement and compromise in the project in regard to DDs. So, we only processed 15 DM keys since August, which is almost a third of the keys we needed to process to reach the ideal 100% migration.

Now, as for our biggest and oldest keyring, and the one that denotes more project involvement, here is the graph for the uploading Debian Developers:

And yes, here you can see the sharp turn we saw in the second half of this year: By DebConf time, we were happy because the red and yellow lines had just crossed. But we were still sitting at 490 DD keys needing to be migrated. Half of the DD keys (compared to almost a fourth for the DM keys).

I'm almost sure we anticipated in our presentation (I know, I should check the video) that, by January 1st, we would have to retire around 300 keys. And I'm very, very happy and proud that we managed to get the number down to 252.

And, yes, people leave things to the end: We already have some more pending requests in the Request Tracker to introduce new keys for our fellow friends who were disabled. We will be working to make keyring pushes more frequent than our usual monthly uploads until requests go back to a sane level.

So, if everything runs smoothly, this will probably be the last of my posts in this regard. This has been quite an interesting (and exhausting!) experience!
