ngi assure: pubsub efficiency
The current implementation of group encryption follows the GPG encryption model. This is inefficient for larger groups, as the message size will increase with each additional participant. Instead we will distributed the encryption material individually before the actual content is send.
There is an existing pubsub branch, which already contains proof of concept code for this. The branch is quite old and needs to receive all recent updates from the main branch. Afterwards the pre distribution of cryptographic key material can be adapted and improved.
