Do you seriously think that anyone would implement crypto based on a reddit post? The lack of mention of modulo multiplication is totally irrelevant for the analogy. You could also say that the box analogy is broken because Eve can take a disc cutter and open the box. Analogies don't have to be perfect duh. I think this is one of the least useful articles I've ever seen on HN.

No. I think people may have taken it as a working example of encryption. Evidently it's not.

The post in question is also specifically replying to someone asking how Bob and Alice can tell a secret, without Eve knowing. The given example does not do that.

Not yet, I've removed the offensive parts. But if you quote from me please quote correctly, your current comment(and the fact that you update it in every 5 minutes) is misleading.

I agree. The original Reddit post is in fact a quite good shorthand simplification and explanation of the concept.

The whole point of simplifying something to an intro level is taking out a bunch of detail so that the most important core premise becomes visible. Adding back the removed detail doesn't change the basic point of the simple explanation it refines it.

The OP appears to have fundamentally missed the point.
