Edit report at https://bugs.php.net/bug.php?id=77134&edit=1 ID: 77134 Updated by: requinix@php.net Reported by: dsumner at sumone dot ca Summary: password_needs_rehash will flag a superior password -Status: Open +Status: Not a bug Type: Feature/Change Request Package: hash related Operating System: all PHP Version: 7.0.32 Block user comment: N Private report: N New Comment: "This function checks to see if the supplied hash implements the algorithm and options provided." It does not try to decide "superiority". If you know the hash should be generated with particular options then pass those to password_needs_rehash.

When a user logs on their password is checked with password_needs_rehash and it work well except that I want certain users to have a password with a higher cost than most users. I can generate their hashes quite easily, but when password_needs_rehash sees these "superior" passwords it returns TRUE and the logon logic then automatically downgrades their passwords. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77134&edit=1
