- 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 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.
9 мин - 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.
8 мин - 4 Keys and passwords: why losing one breaks everything
Every guarantee in this course rests on a key or a password staying secret. Key management is the unglamorous discipline that makes or breaks cryptography.
