My major concern is the nature of the request. Please email me an unencrypted email so that I can send you a PGP key to sign further encrypted comms to a different email address.

Also you’re correct PGP is difficult to handle in email as it’s bolted onto an old and plaintext protocol. I’m learning a lot about email here. Most of my PGP signed packages are done in linux repositories and I admit that I’m not as familiar with it as ECDSA and other encryption algos.
