Something I am passionate about is the ability for each of us to communicate freely while maintaining the confidentiality of our communications. The right to privacy is a fundamental human right.

Privacy and security are not at odds with each other, and are essential to the freedoms and liberties we enjoy. Strong encryption, used liberally, gives us many of the tools we need to ensure we maintain these freedoms.

I would encourage you to learn more, and to make use of the tools at hand to communicate with me. The EFF Surveillance Self-Defense site is a great starting point.

Here are some good ways to contact me, with varying security properties.

Email

ProTip : If you don’t know how to use PGP, but still want to send an encrypted message, you can encrypt a text message to me using Keybase.io and simply copy + paste the encrypted message into an email.

Standard Security

Unless you send encrypted email, the expectation of privacy is pretty low.

Please feel free to encrypt sensitive messages to me using PGP with my PGP public key with ID 0x7FFCB72A6522542E.

Supports : Plain Text / Encrypted Text / Attached Photos / Attached Documents

High Security

Sensitive emails should be sent to my ProtonMail account. It is best if you also use your own ProtonMail account to send messages to me, as that ensures the message will be encrypted end-to-end. Read more about ProtonMail Security.

If you don’t have a ProtonMail account please feel free to encrypt sensitive messages to me using PGP with my PGP public key with ID 0x7FFCB72A6522542E

Messaging

Signal

Signal is my preferred method of secure real-time contact. You’ll need to already know my mobile number to reach me with Signal.

Signal is deemed the “Gold Standard” by those that I respect in the security and cryptography field. Researchers have prepared A Formal Security Analysis of the Signal Messaging Protocol (PDF) and found it to be without any major flaws.

Signal has also demonstrated extremely limited access to metadata that they can make available, even to governments with lawful orders.

I may ask you to verify your safety numbers.

Wire

Wire is also end-to-end encrypted by default. To contact me on Wire you can make a connection request using my Wire username @grempe.

I may ask you to verify your device keys.
