How is the user password generated in bitrix?

Question

1C-Bitrix

Good day.
I am solving the problem of transferring a user database from a site made on bitrix to a site written in Yii2. Most of all, I’m interested in how a password is created in Bitrix, what algorithm is there?
Googled this question and found this:

Salt . md5(Salt . Password)

Salt is generated using the Bitrix function

$salt = randString(8);

. In general, I found this function, tried to implement the same thing, but as expected I got different passwords for the same string, since randString generates a random string.
Tell me how to organize the correct password generation.
Thanks in advance.

What does "faithful" mean? do you need the same as in the Bitrix database ?? Stupidly you copy from a DB. And you can see the password check here bxapi.ru/src/?module_id=main&name=CUser%3A%3ALogin
