  1. 1 Symmetric encryption, asymmetric encryption, and hashing

    Three different cryptographic tools guarantee three different things. Confusing them is the most common source of false confidence.

    9 мин
  2. 2 Digital signatures, certificates, and TLS

    How a browser knows it is really talking to your bank, why a padlock icon means something specific, and what it does not mean.

  3. 3 What end-to-end encryption protects, and what it doesn’t

    Content is only part of what a conversation reveals. Metadata, endpoints, and backups can matter just as much — and encryption does not cover them.
