编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

aes源码。加密的高级标准。。。。。。。。。。(aes)

基于vc++的音频加密软件的设计通过查阅资料对当今比较广泛使用的音频加密算法进行选择，并对其中的三种算法进行其性能方面的比较，找出其中加密性能较好(Audio encryption software design based on VC++through access to information is widely used for today s audio encryption algorithm to choose, and the three kinds of algorithms are compared, and its performance to find out one encryption)

流密码中RC4算法的加密解密的c程序实现(stream cipher)

21加密算法,用vB语言编写实现,可了解各种加密算法的结构(21, encryption algorithm, and realize vB languages, can understand the structure of a variety of encryption algorithms)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

一个用vc编写的aes算法实现，含有128，192，256三种钥匙长度的(a prepared using vc Orangk'aes algorithm, containing 128,192,256 length of the three key)

用VC6.0实现的，运用NTL大整数库实现RSA的加密和解密算法，具有较高的效率！(VC6.0 achieved by applying NTL large integer achieve RSA encryption and decryption algorithms, with high efficiency!)

AES128bit加密算法。在PDF文档中有详细算法描述(AES128bit encryption algorithm. PDF documents are detailed in the algorithm description)

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)
