Recent editions of this book used Java’s Random class to obtain “random” values. This class produced deterministic values that could be predicted by malicious programmers. SecureRandom objects produce nondeterministic random numbers that cannot be predicted.

Most programming languages now have library features similar to Java’s SecureRandom class for producing nondeterministic random numbers to help prevent such problems. From this point forward in the text, when we refer to “random numbers” we mean “secure random numbers.”
