These are the .key files necessary to sign your own TI-compatible operating systems or third-party Flash apps. I do not yet have information on how to do the signing itself for the 68k calculators. For z80 calculators, Benjamin Moody's RabbitSign (Unix, Windows) works well.
These keys are provided for the express purpose of creating software compatible with TI calculators, specifically the bootloader software permanently installed on such calculators. I state in good faith that I believe such action is permitted by United States law. Other uses may not be permitted. I do not support taking actions that are illegal, and I do not take responsibility for any misuse. This material is provided for lawful use only.
These are big-endian hexadecimal.
You can download a .zip file of all the keys here.
