Hello Jack C.,
Thank you for your insightful and detailed comments. We, and I, really appreciate this type of dialog with real users of our software. It’s how we keep doing things which are good, and improve the things we can do better. Without input like yours, it’s so much harder to decide how to continue develop AxCrypt.
Here’s the issue for password-based sharing, if you’d like to follow it to get advance info when it’s coming into AxCrypt: https://bitbucket.org/axantum/axcrypt-net/issues/131/add-sharing-password .
