FYI, there are a number of quite good books on cryptography and the use of
cryptography available. Some of them even manage to get across the key
concepts to be aware of as a consumer of cryptography without losing the
reader in the details of how the algorithms are implemented. :-)
Ross Anderson's Security Engineering is now available online:
http://www.cl.cam.ac.uk/~rja14/book.html
His crypto chapter (5) is both accessible and informative.
