RSA算法 :首先, 找出三个数, p, q, r, 其中 p, q 是两个相异的质数, r 是与 (p-1)(q-1) 互质的数...... p, q, r 这三个数便是 person_key，接著, 找出 m, 使得 r^m == 1 mod (p-1)(q-1)..... 这个 m 一定存在, 因为 r 与 (p-1)(q-1) 互质, 用辗转相除法就可以得到了..... 再来, 计算 n = pq....... m, n 这两个数便是 public_key ，编码过程是, 若资料为 a, 将其看成是一个大整数, 假设 a < n.... 如果 a >= n 的话, 就将 a 表成 s 进位 (s

Overview In this chapter I introduce Borland C++Builder (BCB) and explain what it is about. I also devote considerable time to explaining the purpose of this book and the philosophy behind my approach to technical writing. Technical subjects covered in this chapter include Creating a simple Multimedia RAD program that plays movies, WAV files, and MIDI files. Shutting down the BCB RAD programming tools and writing raw Windows API code instead. Creating components dynamically on the heap at runtime. Setting up event handlers (closures) dynamically at runtime. A brief introduction to using exceptions. This topic is covered in more depth in Chapter 5, "Exceptions." A brief introduction to ANSI strings. This subject is covered in more depth in Chapter 3, "C++Builder and the VCL." Using the online help. Greping through the include and source files that come with the product and with this book.

THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.
