SZ… thank you sincerely. Your suggestions for android solutions gave me a few starting points, and in doing so, picked up on some other perspectives at the same time. trying to link those back to convenient/usable connection to the other platforms I’m reorganizing didn’t produce anything promising, so I’ll be abandoning encryption for the full final intended collection of tools I was building for and keeping the private things in other places.
A win nonetheless. The "comparison of AOS solutions was one of the most beautifully put together technical references I’ve seen and I’m certain will be exceedingly useful. Thanks again.
