[TYPO3-dev] Strange md5 hash problem

[Christian Lerrahn]

Hi,
I have a very strange problem on a site that runs on T3 4.2.6. I cannot
log in to neither the BE nor the installer. Now, the strange thing is
that when I enter a password in the installer, instead of the md5 hash
of what I have entered, an empty line will be displayed with the
failure message. So, it seems that the md5 hash is actually not
generated correctly. The md5() function works properly and if I revert
to version T3 4.2.2 that the site used to run on, everything works fine
again.

I should mention that this site is running on a PostgreSQL
server but as this only shows up in 4.2.6 and the installer doesn't
need the database, anyway, I can't see how that would matter.

Has anything around the md5 hash generation changed between 4.2.2 and
4.2.6? I've only encountered this problem on this one server so far.

Cheers,
Christian
