Modern Cryptography and Privacy

Submitted Nov 30, 2016

“One must acknowledge with cryptography no amount of violence will ever solve a math problem.”
― Jacob Appelbaum

May, 2013 - Snowden
MMM, YYYY - Various corporate breaches, bugs, crypto attacks, privacy breaches

Cryptography is perhaps the single most important computer science concept today. Experts have made remarkable advances in the field, and yet the field seems largely complex and unapproachable due to scary mathematical concepts like factorization, elliptic curves, etc.

Awareness of cryptosystems is very essential today, and this talk aims to bridge that barrier.

This talk will be a modern cryptographic primer.



  • 10 min: Becoming friends with Number theory, symmetric and asymmetric cryptography. A little bit of socialisation.
  • 10 min: Crypto-systems to-dos and to-not-dos, RSA, PGP, AES, TLS, and more 3-letter acronyms!
  • 10 min: pip install cryptography
  • 10 min: How to have really interesting conversations with other people that include words like blockchain.


  • Water bottle for being hydrated
  • Meditate and prepare for a fast-paced crypto-attack!
