Contact Theodore Chu

I care about your privacy and security. That’s why I make it easy for you to contact me securely by end-to-end encrypted email. You can also email me for my Signal number or send me an iMessage at my email.

End-to-end encrypted email ensures that nobody can read your email except you and me and people who have stolen our passwords and two-factor authenticators. For more information, see "What is end-to-end encryption?" on my blog.

The standard end-to-end encryption technology used for email is known as Pretty Good Privacy (PGP). If you are unsure how to use it, then I invite and encourage you to sign up for a free email address at ProtonMail.com. It's very easy to use PGP with ProtonMail. For more information about PGP and how to use it, see "What is PGP encryption and how does it work?" on ProtonMail's blog.

My ed25519 public key for my email is available from the ProtonMail Public Key API. Look at the URL for my email address.
