83Plus:OS:Certificate/Headers:Fields:073
From WikiTI
Synopsis
Field Number: 073h
Purpose Standard Key Header
Parent 070 - Standard Keys List
Usual Size Dh - 40h for OS keys, Dh - 41h for app keys
This field must follow a 071 field and contains the actual key data for the key listed in the 071 field. For the OS keys, the size byte of this field is actually key size too. For the app keys, the size byte for the key and the size byte for the field are not the same number. The reason for this is inconsistency among TI's routines.
