Cryptography & e-commerce --- One of the unsung heroes of e-commerce is how pervasive cryptography has become, and how advancements such as HTTPS have made it safer for users to make transactions online. I'd also add here anti-virus programs that warn users about suspicious websites. Speaking as an anecdote, I know I've refused to buy from e-commerces without adequate security certificates. That said, thinking ahead I worry about what impact quantum computing will have if it ever falls in the wrong hands — might we see someday a large financial crisis from criminals using it for financial crimes? Time will tell, I suppose.
