Similar to phpids?

First of all it is really a drupal module and does not depend on any third party library as phpids
Furthermore phpids is a big module and target of tiny-ids is - like the name says - to keep it tiny, resource-efficient and more simple.

To sum up, I have to admit that the main goal of security enhancement is nearly the same but I think there is a different target audience for tiny-ids because it wants to reach more inexperienced users.
