Summary: Blowfish_encrypt fails with PhP 5.2 and Windows

Initial Comment:
PhP5.2 under Windows does not support the MCRYPT_DEV_URANDOM device.  So, if you have the mcrypt enabled, the blowfish_encrypt and blowfish_decrypt functions will throw the error:

mcrypt_create_iv() [function.mcrypt-create-iv]: Cannot open source device

Since I needed mcrypt for other code and could not update to 5.3 (Drupal 6 contrib module problems), my workaround was comment out the "if function_exists('mcrypt_module_open) conditions in both blowfish_encrypt and blowfish_decrypt (in fucntions.php). This seems to let it fall thru to the working versions.

Permanent fix might be to either not use MCRYPT_DEV_URANDOM or maybe just check for PhP Version in the condition.  See the PhP manual comments for more details on this.
