I think I answered the question I had this morning. #cryptdrive #cryptpad is separate from #nextcloud, doesnot use #activPub but has the etho of what #fediverse stands for.

Its a secure way to share a document. All parties need to have an account and it is really easy to set one up. I did it almost by accident.

Just remember your account name and password. there is no password recovery and that is a good thing and required.

still working out where cryptdrive ends and cryptPad starts
