Secure Programming Cookbook for C and C++: Recipes for Cryptography, Authentication, Input Validation & More

This Book is from a chapter on secure random number generation in a book on secure programming in C and C++. It discusses the importance of high-quality randomness, especially for cryptographic applications, and the challenges of obtaining true randomness from deterministic computers. The chapter explores various methods for generating secure random numbers, including using operating system interfaces (/dev/random, /dev/urandom, CryptGenRandom), application-level generators based on block ciphers, stream ciphers, and hash functions, and techniques for collecting entropy from diverse sources like keyboard input, mouse movements, and system timers. The text emphasizes the need for conservative entropy estimation and cryptographic post-processing to mitigate potential attacks. It also provides code examples and API designs for implementing these techniques.
