This is hacker news. I think that we are all here to learn. We all have different levels of expertise as well as areas of interest. I'm personally not working a full time coding job yet because I'm still in school and I still have quite a bit that I want to learn just hacking around on my own smaller projects.

The fact that the concept of a salt isn't totally automatic to him or that he misspelled nonce only means that he shouldn't be designing security systems right now. There is a lot that we can all learn, some of us just have farther to go than others.
