You can encrypt a message so that only I can read it โ even if it's intercepted in transit. Here's what that means and how to do it.

PGP (Pretty Good Privacy) is a battle-tested encryption standard used by journalists, security researchers, lawyers, and anyone who needs to communicate privately. It works using a key pair:
The result: a message encrypted to my public key is mathematically unreadable to anyone but me โ not your email provider, not a network eavesdropper, not anyone.
For everyday conversation, a regular email is fine. This is here when you need it.
The easiest path is a free tool called Keybase or a local app like GPG / GnuPG. The general steps are the same either way:
[email protected] using my public key. Your tool will produce an armored text block starting with -----BEGIN PGP MESSAGE-----.Prefer a quick browser-based option? PGPainless and OpenPGP.js let you encrypt directly in your browser without installing anything.
Before encrypting anything sensitive, confirm the key fingerprint matches. You can check this in your PGP software after importing the key โ it should read:
If the fingerprint doesn't match, don't use the key โ contact me through another channel to verify.
