MD5 phpbb v.3 question

[Mariane]

First of all, as it's my first post here, hello to everyone

All the hash codes of a database linked to a phpbb forum start with $H$9
Exemple: $H$9xxxxxxxxxxxxxxx which corresponds to test00
Is $H$9 part of the hash code or should I remove it before running the program?

EDIT: Hash has been removed.
