I have mentioned my new app for adding zero-knowledge encryption to file sharing services that don’t have it natively in this and this other post. Right now I have a group of alpha testers uncovering bugs, and the first one coming in is that the instructions on the app itself are rather terse. This post hopefully will help users as well as group administrators.
Problem: A well-defined group of people formerly working at a single location used to pass along pieces of paper containing confidential information so group members could comment and expand. But after covid they find it hard to get together in one place and, since every member has a computer, they would like to be able to do it online. But confidentiality remains very important, along with integrity of the information. What can they do?
