Hi, all,
This is Shirley from, I am a newer of IMA.
I have some questions. Can you help?
According to the guide: https://sourceforge.net/p/linux-ima/wiki/Home/#linux-extended-verification-module-evm.
1. How to calculate the template hash in /sys/kernel/security/ima/ascii_runtime_measurements? Like below:
PCR template-hash filedata-hash filename-hint

2. Ubuntu 20.04 is installed on my machine, but ascii_bios_measurements can’t be found under /sys/kernel/security/tpm0/.
There is only binary_bios_measurements under tpm0/.
So where to find the bios measure list on Ubuntu 20.04?
Thanks.
