good merkle hash tree python implementation?

I found this implementation in Python.

Also on Github here there seems to be a basic implementation, worth giving it a try.

There is currently a new one here, generating also consistency-proofs except for the standard (audit).

I find it highly configurable (you can select hash and encoding types) and very convenient (you can encrypt strings, bytes and whole files very simply). I'm not sure about the tree structure (it seems a bit different from other implementations) but definitely worth giving a try.
