Comment (by Otto42):

 I think you might need a php version check on the `if
 (function_exists('mcrypt_create_iv'))` line as well. On a Windows machine
 running 5.2.x, where the mcrypt extension is also enabled, a call made
 using `MCRYPT_DEV_URANDOM` will cause a "Cannot open source device"
 warning. This warning will prevent logins if display_errors is enabled
 (which it sadly is by default on most hosts).

 Alternatively, error suppression by using `@mcrypt_create_iv()` would
 probably work just as well.
