| An Introduction to Cryptography: Richard A. Mollin. Intended for a one-semester introductory undergraduate course in cryptography. Covers symmetric and public key systems with chapters on advanced topics. |
| Applied Cryptography: Bruce Schneier. A comprehensive tutorial and reference but a little light on mathematical theory. |
| Codes and Ciphers: Robert Churchhouse. Describes and analyses systems from the earliest to the most recent. |
| Contemporary Cryptology: Gustavus J. Simmons. Subtitled "The Science of Information Integrity". Has emphasis on the cryptographic elements of the subject. |
| Cryptography and E-Commerce: Jon C. Graff. Geared to nontechnical managers who want to explore the underlying concepts of this topic. |
| Cryptography book recommendations: Cryptography book reviews, links to online erratas, and free book downloads. Most books have charts that recommend prerequisite books, mathematics and programming language experience. |
| Cryptography Decrypted: Mel and Baker, has sample chapters. |
| Cryptography for Visual Basic: Richard Bondi. Subtitled "A Programmer's Guide to the Microsoft CryptoAPI" which describes what the book is about. |
| Cryptography Theory and Practice: Douglas Stinson. Subtitled "Discrete Mathematics and Its Applications". Written with more emphasis on theory than practice, as acknowledged in the preface. |
| Foundations of Cryptography: Oded Goldreich. Focuses on the basic mathematical tools needed for cryptographic design: computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs. |
| Handbook of Applied Cryptography: The online version of the 1996 CRC book by Menezes, van Oorschot and Vanstone (5th edition) in PostScript and PDF formats. |
| In Code: Sarah Flannery's supplement to her book "In Code", describing her Cayley-Purser algorithm. |
| Primality and Cryptography: Evangelos Kranakis. A comprehensive account of recent algorithms developed in computational number theory and primality testing. |
| RSA Security's Official Guide to Cryptography: Burnett and Paine. Explains the differences between symmetric-key and public-key cryptography, how PKI and X.509 affect security and how the RSA algorithm works within protocols. |
| Security Engineering: Anderson, Ross. Author describes book in his own words. He explains how "pure" cryptography is not quite so pure when expressed in the context of real world applications. |
| The Code Book: Simon Singh. Traces the development of codes and code-breaking from military espionage in ancient Greece to modern computer ciphers. |
| The Interactive Cryptography Tutorial: Online tutorial with useful info and links. |
| The Mathematics of Ciphers: S.C. Coutinho. An introduction to number theory and its applications to cryptography. A revised and updated translation from original in Portuguese. |
| The Twofish Encryption Algorithm: Schneier, et al. Covers design, performance, instructions and source code in C. |
