Not sure if this is the correct place to post. If not, maybe someone knows where I should go :)
I am curious about cryptography and have taken some related courses through my studies. However I was wondering if anyone have any reccommendations for books on the topic. I am not looking for textbooks, but rather "fun" books that do contain mathematical explanations. Perhaps recreational mathematics is a good description. I have looked at The Code Book by Simon Singh and The Code Breakers by David Kahn.
In advance: thank you :)
