Arithmetic and Number Theory in C -- Number Formats: The Representation of Large Numbers in C -- Interface Semantics -- The Fundamental Operations -- Modular Arithmetic: Calculating with Residue Classes -- Where All Roads Meet: Modular Exponentiation -- Bitwise and Logical Functions -- Input, Output, Assignment, Conversion -- Dynamic Registers -- Basic Number-Theoretic Functions -- Rijndael: A Successor -- Large Random Numbers -- Strategies for Testing LINT -- Arithmetic in C++ with the Class LINT -- Let C++ Simplify Your Life -- The LINT Public Interface: Members and Friends -- Error Handling -- An Application Example: The RSA Cryptosystem -- Do It Yourself: Test LINT -- Approaches for Further Extensions.

This book covers everything you need to know to write professional-level cryptographic code. This expanded, improved second edition includes about 100 pages of new material as well as numerous improvements to the original text. The chapter about random number generation has been completely rewritten, and the latest cryptographic techniques are covered in detail. Furthermore, this book covers the recent improvements in primality testing.
