        • 17 - It is Never DNS

          On this episode we give a very brief overview of what DNS is. We explain the joke of why it is never DNS, but often it is.

            • 15 - What is Time-based One Time Passwords?

              TOTP

              • Randomness
              • RNGs
              • PRNGs
              • Seeded PRNGs
              • Hash Functions
              • What are they / Where are they used?
              • Important to keep in mind that there are crytpographic and non-cryptographic hash functions
              • TOTP combines Seeded PRNGs and Cryptographic Hash Functions to generate predictable, “random” codes using a seed and the current time.
              • As long as your device has the correct time, you can generate the correct code
              • This seed is present on your device (usually loaded through a QR code) and on the server.
              • When you log in, the server knows what the code should be (based on current time), so it can confirm that you have the right code
