What OpenPGP IMHO liked to solve is to use public key cryptography
     for
     the masses,
     where every Joe user average can communicate with strangers globally
     and somehow
     knowing that person X is maybe person X, when using the classic WoT.
     Question would be, do we really need this? For business purposes, I
     would not need
     this and for private use only also not much.

   Do we really need cryptography at all?
   It seems we need it very badly because our devices, networks, and
   communities are very insecure.  In the USA we had a huge political
   schism in the past few years.  People do things.  Governments do
   things.  Businesses do things.
   These things work so simply, because precautions are not taken.
   But that's always been the case.  Citizens get simple locks that any
   locksmith can pick.  Anybody can train to be a locksmith and open every
   door.
   On the internet, knowledge has traveled much faster and wider than it
   has in the past.

     P.S. I suggest also in this regard to take a look, in case you have
     Rust installed,
     at sequoia-pgp, which also allows you to create a key pair without a
     UID, bit
     AFAIK GnuPG can not handle such pub keys currently.

   yeah thanks.
   I imagine pro gpg'ers know what's up, I don't really.  just was
   verifying some media.
