These are the OS signing keys for different Texas Instruments calculators.
The key for the TI-83 calculator was first published by someone at the unitedti.org forum in this message.
He or she needed several months to crack it and the other keys were found after a few weeks by the unitedti.org community through a distributed computing project.
The keys make it possible to sign your own operating system for the Texas Instruments calculators.
Texas Instruments now contacted several people with a DMCA notice to take down the keys from their websites.
Some of the websites which got a DMCA notice are: unitedti.org, brandonw.net and reddit.com.
Here are the three keys:

These keys are posted as a public service to the Internet community as the DMCA is not applicable under UK law and being the owner of this site, the server it lives on and the network which it is hosted on makes me best placed in fighting any attempt by Texas Instruments to have it taken down.
You cannot copyright a number; especially a private key which, by definition, has not been published by Texas Instruments but has been discovered independently by a third party.
