Thank you Qi. 

i recommend we file a bugzilla on the scope of the problem

After the scope is agreed, then you can send the patch. 

For example, I can ask why not remove the sha1supported field at all?

I hope the community can reach consensus on the problem statement at first. 


thank you!
Yao, Jiewen

I agree.

We already have a number of BZs related to the disablement of SHA1 and MD5:

https://bugzilla.tianocore.org/show_bug.cgi?id=1682
https://bugzilla.tianocore.org/show_bug.cgi?id=2943
https://bugzilla.tianocore.org/show_bug.cgi?id=3003
https://bugzilla.tianocore.org/show_bug.cgi?id=3021
https://bugzilla.tianocore.org/show_bug.cgi?id=3027
https://bugzilla.tianocore.org/show_bug.cgi?id=3079

We should certainly track the change for Tcg2Config too, in a new BZ.

Thanks
Laszlo
