Setting up a PGP secure marketplace involves encrypting each transaction with public and private keys, ensuring that only the buyer and seller can read order details and payment info. Sellers often list their PGP fingerprint on their profile, and customers use it to send encrypted messages. It's a bit more clunky than a standard shopping site, but the privacy control is unmatched for sensitive purchases.
