PGP: quick explanation
PGP (Pretty Good Privacy) is a way to protect the contents of a message using public‑key cryptography. You encrypt with our public key; only we can decrypt it with our private key.
- Import our public key from the download link.
- Write your message (e.g., crypto receipt + postal address) and encrypt it to our key.
- Email the encrypted text (the long block that starts with
-----BEGIN PGP MESSAGE-----
).
Heads‑up: email subject lines and metadata are not encrypted. Keep subjects generic.
