Groups are like shared subkeys. The admin of the group holds the main key, but each member holds a subkey that allows them to decrypt any data encrypted for the group key or sign any data as the group key. The feature should implement group management features like removing someone from the group, which will create a new subkey, and send it to all remaining members of the group in such a way that automatically updates their subkey for that group, allowing them to continue receiving messages from the new sub key. Adding members to the group is as simple as sharing the subkey. Each client will retain a local roster of groups they are a part of, who the other members of groups are, and this will obviously be stored encrypted on the network to their account, and as such will be shared with any other clients also connected to that account. Documentation should be added for groups, with implementation examples such as having an authenticated group such as authors on a blog, where only posts from authors get displayed, or private group chats in a messaging apps where messages to the group are encrypted for the group.
