comment A simple block cipher based on the SHA-256 hash function
This is almost the exact same algorithm as listed on this question: crypto.stackexchange.com/questions/48/… The answers there also provide some pretty good insight.

This is technically off topic, based on question #3 in the FAQ. But... we can have fun every once in a while, right?

comment Is a book cipher provably secure?
Right, I would say that the main difference between this and a one-time pad is that: a one time pad's security is based on all possible pads that could be created, whereas a book cipher's security is based on all possible books that have been created.
