How passwords are stored in RT?

This is for the compliance part.

In my organisation we have deployed RTIR and in order to comply with company policy we need to provide answers to some questions.

I need to know How passwords are stored in RT/RTIR ?

Any documents around this is appreciated.

Thanks,

In the code I see

By default, the method is currently C<bcrypt>.

There are the methods _GeneratePassword_bcrypt and _GeneratePassword_sha512 in User.pm
