Bulk user creatation 200+ users

Konnichiwa from japan.

Is there a simple way to bulk create users ?

If possible I'd like to create a bash script to create account/user.yaml
using list of names and passwords that are already created in other systems.

or is the hashed_password: recipe disclosed? so I can follow the recipe to create hashed_password for each user by scripting.

newuser -u usernamegoeshere -p passwordgoeshere -e emailgoeshere would probably be easiest. All documented by the login plugin.

Thank you very much!!
