One of my favourite CoverDrop details: out-of-band verification of the trusted organization key which signs the entire key hierarchy. Its digest is included in the imprint of every printed Guardian newspaper, removing the need to trust CAs 🔑🗞️ more details: www.coverdrop.org

The picture shows a smartphone and the imprint of a newspaper. The smartphone displays a screen from the SecureMessaging feature showing a key digest. The newspaper imprint shows the same digest. The digest consists of a number of randomly-looking letters and digits.

We ended 2023 with a talk at #37C3. @raphaelrobert.bsky.social and Konrad presented Messaging Layer Security (MLS).
The room was packed and some people couldn't attend – luckily the talk is now online.

MAPS Messaging

@mapsmessaging.bsky.social

MQTT is fast, but without authentication, it’s vulnerable. MAPS Messaging adds SASL authentication for secure, identity-driven MQTT messaging. No compromises on speed. No gaps in trust.
