live-config scripts 0030-user-setup and 0030-live-debconfig_passwd

[paul@gilbertson.biz]

As a way of changing the default user password, there was a way of 
placing an encrypted password string in the /etc/shadow account for 
debian live systems by using the "0030-user-setup" script.  Here is part 
of the script:
                   # Default password is: live
	# passwords can be generated with 'echo "live" | mkpasswd -s',
	# a blank password is 'U6aMy0wojraho'.
	_PASSWORD="8Ab05sVQ4LLps"

Since Bullseye, all hashing is supposedly done with yescrypt as the 
default.  However, the only the following weak hashing algorithm of 
"descrypt" seems to work for changing the user login password. When I 
use  "mkpasswd -s -m descrypt"  everything works flawlessly and I can 
login with the new password.  Is there a way of using the "mkpasswd -s 
-m yescript" with this 0030-user-setup script so I can login with the 
normal user with a custom password and have a more secure hash?

Another question is what is the difference between using the live-config 
script labeled "0030-live-debconfig_passwd" as supposed to 
"0030-user-setup".  Since the 0030-user-setup comes last would you need 
to use both scripts or just the last?  When I use just the custom 
"0030-user-setup" script with the  with and encrypted password string 
made with "mkpasswd -s -m descrypt" the  password login works.  When 
would I need to use the other script?
