In the latest episode of the Three Devs and a Maybe podcast, hosted by Michael Budd, Fraser Hart, Lewis Cains and Edd Mann, they welcome back a guest for another round of security discussions: Scott Arciszewski around symmetric and asymmetric encryption.

In this weeks episode we are lucky to be joined again by Scott Arciszewski. We start off the show by discussing the difference between Symmetric and Asymmetric Encryption, what Authenticated Encryption is and how secret-keys are exchanged using Diffie-Hellman. From here, we move on to highlight how Elliptic-curve cryptography works, what DNSCrypt is and why prime numbers are so important in cryptography. Finally, we touch upon multi-factor authentication, how one time passwords work, SMS vulnerabilities and how to manage password recovery.

There's a wide range of security and cryptography related topics mentioned and linked in the post.
