Subject: [PATCH] mokutil: Add option to print the UEFI SBAT variable content
This variable contains the descriptive form of all the components used by
the operating systems that ship signed shim binaries. Along with a minimum
generation number for each component. More information in can be found in
the UEFI Secure Boot Advanced Targeting (SBAT) specification:
https://github.com/rhboot/shim/blob/main/SBAT.md
Since a SBAT variable contains a set of Comma Separated Values (CSV) UTF-8
encoded strings, the data could just be printed without the need to do any
previous processing.

Subject: [PATCH] mokutil: add mok-variables parsing support
his patch adds support for getting mok variables from
/sys/firmware/efi/mok-variables/$NAME , if they are present, as well as
for checking MokListRT, MokListRT1, MokListRT2, etc., for any of the mok
variables.

Subject: [PATCH] mokutil: remove "--simple-hash"
The simple-hash password format is used by the very early MokManager and
not the default format anymore after we changed to password-crypt.
Remove the code to reduce the code size.

From f552d2bb570568673d293fcb2263a2ee8c3333de Mon Sep 17 00:00:00 2001
From: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH] mokutil: use EVP_Digest()* functions instead of the
deprecated SHA1_*()
The SHA1_*() functions have been deprecated since OpenSSL 3.0, this leads
to compile errors when building with -Werror=deprecated-declarations, i.e:
mokutil.c: In function 'print_x509':
mokutil.c:424:9: error: 'SHA1_Init' is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]
424 | SHA1_Init (&ctx);
| ^~~~~~~~~
...
instead, the EVP_Digest*() functions could be used. Port to them and avoid
these build failures with the latest OpenSSL 3.0 version.
