Thanks for the informative message and agree that you’d have to absolutely know your contacts in person...and not knowing a thing about PGP keys, I’d require a lot of training. Hope things don’t get to that point, but every day, things seem just a little bit worse.
There are a lot of folks here on FR who could give you pointers on how to do PGP/GPG. I think it would be useful to many and might just start a vanity someday soon for that purpose.
