Here are a few "crypto" books I recommend.
These are not random recommendations.
We own all of them and would not hesitate recommending them to a friend.

Cryptographic Theory

Cryptography : Theory and Practice (Discrete Mathematics and Its Applications) by Douglas R. Stinson - the best in-depth crypto book money can buy. Surprisingly clear for a book with a heavy mathematical content.
Handbook of Applied Cryptography (CRC Press Series on Discrete Mathematics and Its Applications) by Alfred J. Menezes, Paul C. Van Oorschot (Editor), Scott A. Vanstone (Editor)

Decrypted Secrets : Methods and Maxims of Cryptology by Friedrich L. Bauer - one of our all-time favourites, back in print ! This book combines historical notes with a very solid mathematical background. It is one of the very few books that adresses modern cryptanalysis in a formal way.

Practical Network Cryptography

SSH The Secure Shell : the definitive guide (by Barrett and Silverman). SSH has become the de-facto standard for remote secure Unix system administration, but it is much more than that, as this masterful book clearly explains.
A Technical Guide to IPSec Virtual Private Networks by James S. Tiller. IPSec and VPNs have quickly become household names, so to speak. However, the underlying concepts are sometimes hard to understand and harder to implement. This book cuts a path through the jungle.


Entertainment - History

Crypto : how the Code Rebels Beat the Government -- Saving Privacy in the Digital Age. Levy recounts the battles that had to be fought in order to liberalize the use of cryptography. If you want to have a great tile learning why you are now able to download and use aCrypt legally, this is the book to check.
Cryptonomicon by Neal Stephenson - a great dual thread novel where crypto links the second World War to our day. Probably the only novel where crypto plays such an important role.
The Codebreakers; The Comprehensive History of Secret Communication from Ancient Times to the Internet by David A. Kahn - this massive, carefully documented history of cryptography remains unmatched.
