Thanks for reporting this. I had no idea mcrypt was in such bad shape.

There seem to be two options:

1. Using OpenSSL, which requires the OpenSSL extension
2. Use defuse/php-encryption which has no dependencies but requires PHP 5.4

I'm more in favor of defuse/php-encryption since it has no dependencies, even though it will require us to drop PHP 5.3 support (it's about time anyway).

Usage of mcrypt within this bundle has now been deprecated in favour of defuse/php-encryption, which is now the default encryption provider for new installations. Existing installations keep using mcrypt in order to maintain BC. See the Change log for 1.3.0 for more information.

Thanks for reporting this issue.
