Using libmcrypt-2.4.10 on Mac OS X 10.0, compiled with 

--with-apache=/usr/local/src/apache_1.3.19 --with-mysql=/
usr/local --with-mcrypt --enable-track-vars --disable-debug


My sample script:

<?php

$stuff = mcrypt_cbc(MCRYPT_BLOWFISH,"This is my key","this 
is my message",MCRYPT_ENCRYPT);
print base64_encode($stuff);

?>

produces this error:

Warning: mcrypt module initialization failed in /Users/
clewis/dev/website/public/asdf.php on line 3


libmcrypt was compiled with --disable-posix-threads as 
suggested on the PHP mcrypt page.

First, the "--disable-posix-threads" requirement for libmcrypt isn't a requirement anymore.  As of libmcrypt 2.4.x, you don't need it.

Second, I think you should be using the 2.4.x-style mcrypt functions.  Look at example 2 at http://www.php.net/manual/en/ref.mcrypt.php

Third, blowfish is broken in libmcrypt.  It will encode/decode internally, but don't rely on it if you need to pass data to a non-PHP application (e.g. Perl).

Another mcrypt bug, I'll check this one out. It may be a platform depended bug BTW.

Incidentally, I tried the new-style mcrypt functions as 
Colin suggested, and got a similar warning: "Could not open 
encryption module."

I guess this could be an OS specific problem. I've no access to a Mac OS X machine unfortunately.

Derick: Bug 10281 reports this on Linux. Probably not platform specific.

not a php bug regardless of os
