It does support GCM now, it's even the new default(!).

I've added support for all AEAD modes, that PyCryptodome supports, and 
supplied a small encryption mode conversion tool as well.

I plan to add authenticated service and username support via associated data 
as well (that protects against tampering with these values). It might be a 
good idea to record and secure the number of entries as well.

Cheers,
Pete
