    So basically, you are saying don't worry about security because he can leave security in the hands of others that know security. Because other people are more trustworthy with his own security. Sounds perfectly logical (insert sarcasm here). He can learn the basics of cryptography and begin building his own system. All of the best cryptographers started somewhere. Instead of giving him/her a crap story about how futile it may be as a beginner, why not, instead, ADVOCATE that they continue to learn and test and present the system to the public for testing.

    What was the problem with the do-it-yourself brain surgery? You seem to be placing it as an example of a failure, but I am unable to find the problem in the given scenario. Commented Apr 17, 2017 at 20:49

    @Yokai, I think that's what he is already saying. Roll your own crypto as a learning process, then throw it away and use something experts have been testing for years. Commented May 29, 2019 at 20:05

    @Yokai The point of this is that you shouldn't attempt to design your own scheme for production. Experimenting on your own and trying to break the things you make (or post it online for others to try to do so) is 100% recommended and there's nothing wrong with that, but using that experiment to encrypt your customers' credit card numbers is obviously problematic.
