Hello,

For create descriptor and txe binary, i found this documentation:

In the chapter 5.2 Creating Secure Boot Manifest and Signing IBB

5.2.1 Prerequisites

Public and private key to be used for signing the BIOS

- how to generate  Public and private key ? you can use ssh-keygen -t rsa -f ./keystest for example ? which type key ? rsa, dsa, 1024,2048 ?

- i don't find IBB binary on intel business portal, where is ?
