Manual:WrapOldPasswords.php

Details
wrapOldPasswords.php file is a maint-scripts>Special:MyLanguage/Manual:Maintenance scripts|maintenance script to wrap all passwords of a certain type in a specified layered type that wraps around the old type.

Since MediaWiki 1.24, password hashes will automatically be updated to PBKDF2 as users log in.

If necessary, the old MD5 hashing can be restored by changing   to 'B'.

wrapOldPasswords.php can wrap all passwords in PBKDF2 (or the hashing algorithm of your choice) if you don't want to wait for your users to log in.

'''Table with script parameters still missing. Especially the names for the different types are important - script is useless without them...'''
