The Cryptool website has a wealth of information on how the past-present and future crypto-algorithms work. Download and install the freeware (Cryptool 1.4.10 is the current version), an easy and fun way to explore the inner working of the algorithms even further.
There is also a very good overview of Cryptology in this document.
The site is well done, clear and easy to navigate. Excellent work!
