All TI Signing Keys Factored
Posted by Astrid 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.

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

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.
