Can you explain? I don’t know much about encryption/PGP but I don’t quite follow how exchanging a key via PGP prevents an imposter from posing as someone else?

So you can have a trusted network that allows you to build a database of public keys of important people. Look up public key cryptosystems. A worthwhile read, the entire internet is built on this technology. https://en.wikipedia.org/wiki/Public-key_cryptography https://en.wikipedia.org/wiki/Public-key_cryptography
