Don't know how much you want to develop this but I would suggest the following additions to VukExtract :
1. support for all KEYDB.cfg entries (currently missing DATE and UNIT keys)
2. include presence of BD+ in comment
3. include MKB version in comment
4. automatic upload of VUK to AACSUpdater
5. store all found keys in backup file which allows submission to AACSUpdater in a later stage
I have explained the benefit of having all keys in this
