All TI Signing Keys Factored
Posted by Duncan on 13 September 2009, 00:13 GMT

In July, we reported on the factoring of the 0004 key, required for the signing of TI-83+ and TI-83+ SE OS updates. Thanks to an unprecedented community effort, all of TI's signing keys have been factored (Details on the United-TI thread), including both operating system and application signing keys for every upgradeable model.

The Nspire and Nspire CAS aren't included; very little is known about them yet.

These keys allow free user-created operating systems to be installed without having to use awkward work-arounds such as Free83P and FreeFlash. Free operating systems already exist for the TI-83+, the TI-89, and the TI-92+. As of this writing, none of the operating systems available on ticalc.org right now are signed, but we look forward to accepting signed OSes from authors.

To sign your own operating system or Flash apps, you will need Benjamin Moody's RabbitSign (Unix, Windows). For 68k calculators (TI-89 / TI-89 Titanium / TI-92+ / Voyage 200), Brandon Wilson's resign68k works as well.

Yes, due to a gigantic effort by the entire community, via the boinc project, we could factor keys within a week.

Everyone on the boinc client.

The keys are factored, and downloaded at several locations, so we won't lose them.

What happened to TI's C&D letters?

We ignored them?

Now that all the keys are factored and they're being spread throughout the internet, there's no stopping this. Any further letters/orders would be a waste of time. Perhaps they've realized that by now (but I doubt it).

Yes. It should be on at least 20 computers for record, maybe more. We will never lose them, and any further attempts to give C&D notices would be illogical, difficult, as well as costly for TI.

A total wast of time for TI to do anything. Besides, we still didn't do anything illegal, and TI failed to realize that.

So spread the keys!!!

It's definitely exciting! I'm just afraid of the ramifications of this a little. I mean, this whole procedure was in complete defiance of TI's wishes....

I just dunno. Glad we finished them, though. Even the troublesome 73s as well, right?

Yes, everything from the 73 to the Voyage 200.

What TI wants hasn't mattered to this community since day one. We want third-party OSes installable in an easy way, and Flash applications on any model, and now we have it.

We factored keys within a _month_, not within a week ;)
But yeah, the community has definitely made a significant achievement here.

While I'm at it: we're redirecting the power of the rsals BOINC grid towards more general-purpose integer factoring. A mail was sent to all participants.

The first one was done in two months, and a week.

Considering how many keys there were, and how long ago this all started. (Jul 9, 2009).

That means that out of 12 keys, it took us 65 days. That means it took us about 5.5 days for each key.

Congrats everyone!

(but: wasn't the 0004 key the first to be factored?)

Yes, it was. Why?

The 0004 key only allows 83+/SE OSes, not 84+/SE ones, or anything else.

unfortunately, unitedti was sent a dmca notice about the OS, but not about the apps.

I'm amazed they took this long.

This will do nothing...the keys are out in the wild and everyone that wants to experiment with them knows who to contact to get them.

Wikileaks articles and torrents are going to go up about this, and that can't be taken down. TI is wasting their time. It's pretty amusing now that we're done.

Yes. The keys are out there. They can send as many DMCA notices as they want, but if they take us to trial, it will be on what grounds? We did absolutely nothing wrong.

I hope we don't try to break the nspire. I would rather see TI suffer in trying to sell that crap.

But maybe somewhere down the road, when TI has dropped the nspire and moved on to some other crappy spire. Then... we strike... opening up the hardware for assembly programming lol.

--------------------

Wait... what was i saying... lets just crack the nspire asap lmao.

seriously, cracking the nspire will unlock a whole host of possibilities.

what about the 84+/SE OS key? I want that. It wasn't in the zip file I downladed, and someone told me that the 83+/SE OS key won't work.

On topic, the NSpire is crap, but with an NSpireload of memory <font-color:"Light blue">(get that, I called that crap, then used it as a synonym of crap)</font>

Are you sure you don't have the 00A0 key?

The 83+/SE (04) key works only on the 83+ and 83+SE.

The 84+/SE (0A) key works only on the 84+ and 84+SE.

The 0A key is in every zip I've seen, and it's on Wikipedia and Wikileaks.
