DES加密算法的C＋＋实现-DES encryption algorithm in C++

RSA的小程序，源码产生随机素数调用方法：N.GetPrime(bits)返回值：N被赋值为一个bits位（0x100000000进制长度）的素数-RSA small program source random-number call methods : N. GetPrime (bits) Returns : N has been assigned a bits- (0x100000000 band length) of prime numbers

一个RSA算法的完整实现，有超长密钥-an RSA algorithm integrity, and it is extra-long keys

C++下的base64编码，能够支持任何数据进行base64编码。 -C++ Under the base64 encoding, can support any data base64 encoding.

这是一个加密程序，可对字符串进行加密，字符串和密钥的内容和长度可以设置。-This is an encryption program that encrypt the string, string and key content and length can be set.

本书真实系统地介绍了密码学及该领域全面的参考文献。 全书共分四个部分，首先定义了密码学的多个术语，介绍了密码学的发展及背景，描述了密码学从简单到复杂的各种协议，详细讨论了密码技术，并在此基础上列举了如DES、IDEA、RSA、DSA等10多个算法以及多个应用实例，并提供了算法的源代代码清单。 全书内容广博权威，具有极大的实用价值。自出版以来，得到业内专家的高度赞誉，是致力于密码学研究的专业及非专业人员一本难得的好书。-This book introduces the real system and the field of cryptography comprehensive references. Book is divided into four parts, first of all define the term more than cryptography, introduced the development of cryptography and background, describes cryptography from the simple to the complex variety of the agreement, a detailed discussion of cryptographic techniques, and on this basis cited, such as DES, IDEA, RSA, DSA algorithm, as well as more than 10 examples of multiple applications and provides the algorithm source code on behalf of the list. Broad authority of the contents of the book, has great practical value. Self-publishing has been highly praised the industry experts, is dedicated to the study of cryptography professional and non-professional a rare book.
