https://phpc.tv/videos/watch/eeac4436-24bf-4671-b5cc-c9a32e746c8b Alice and Bob have covered the basics of secure communication but cryptography can offer us more than this. After a brief refresher on the basics, we'll take a look at some of these other aspects of cryptography including hash functions, elliptic curves and quantum cryptography. Then we'll take a look at some practical applications answering questions such as: can I trust a web of trust? or should I use a block chain for this?
