AIDE (Advanced Intrusion Detection Environment), developed in C, monitors program and configuration files for changes. It calculates their checksum using six different hash methods (to prevent collisions) and detects changes to timestamps, permissions, and ownership. AIDE also recognizes if files have been added or removed.

To be frank, either a hash is good enough (and in practice, even just md5 would do) - or not. Raising this as an advantage puts the rest of the claims into quite some doubt and makes it more sound like snakeoil than anything else. (And yes, there'd be a lot to be said about "monitors program and configuration files for changes" as well, because if I can change those, I can just as well replace AIDE with a 2-line script mimicking AIDE's output to claim that everything is fine).
