This password based user authentication is to verify user when a user
wants to enter BIOS setup page.
The DXE driver registers report status code listener.
When it gets (EFI_SOFTWARE_DXE_BS_DRIVER | EFI_SW_PC_USER_SETUP) progress
code, it will let the user input password.
If and only if the user inputs the right password, the status code handler
will return and let the setup driver continue running.
If the user inputs the wrong password, the status code handler will let
user try again.
If the user inputs the wrong password 3 times, the status code handler will
reset the system.
The DXE driver also register a setup page in setup browser, so that
user may update the password.
The DXE driver uses SMI to let SMM driver do the password verification
and management.
The SMM driver registers SMI handler to perform the request from DXE.
The password must meet below criteria:
1) Length >= 8 char
2) It must include lower case, upper case, number and symbol.
3) It must not duplicate with 5 previous password.
If above criteria is met, the password will be saved to a read only UEFI
variable. The format is password hash+salt, which is generated by
Pkcs5HashPassword algorithm (SHA256+1000 iteration).
If the SMM driver gets wrong password 3 times, the interface is locked
and does not accept more request.
If the SMM driver will detect IsPasswordCleared() at the entry point and
clear the password if IsPasswordCleared() is TRUE. This can be used when
the user forgets the password.

Subject: [PATCH 5/6] SecurityPkg/Password: Add Password based UserAuthentication modules.
This password based user authentication is to verify user when a user
wants to enter BIOS setup page.
The DXE driver registers report status code listener.
When it gets (EFI_SOFTWARE_DXE_BS_DRIVER | EFI_SW_PC_USER_SETUP) progress
code, it will let the user input password.
If and only if the user inputs the right password, the status code handler
will return and let the setup driver continue running.
If the user inputs the wrong password, the status code handler will let
user try again.
If the user inputs the wrong password 3 times, the status code handler will
reset the system.
The DXE driver also register a setup page in setup browser, so that
user may update the password.
The DXE driver uses SMI to let SMM driver do the password verification
and management.
The SMM driver registers SMI handler to perform the request from DXE.
The password must meet below criteria:
1) Length >= 8 char
2) It must include lower case, upper case, number and symbol.
3) It must not duplicate with 5 previous password.
If above criteria is met, the password will be saved to a read only UEFI
variable. The format is password hash+salt, which is generated by
Pkcs5HashPassword algorithm (SHA256+1000 iteration).
If the SMM driver gets wrong password 3 times, the interface is locked
and does not accept more request.
If the SMM driver will detect IsPasswordCleared() at the entry point and
clear the password if IsPasswordCleared() is TRUE. This can be used when
the user forgets the password.
