Yes. And your software suggestions are excellent for 2019. I just wonder whether in 10 years it would be better to have a standard improved/developed, instead of a collection of one-vendor tools where the code is specification. That said I don't have high hopes for PGP given its maintenance problem.

Thanks for writing on the subject, even if the subject should already be clear to majority of technical people!
