加密算法的小程序，支持加密多种文件，用vc语言编写。

用VERILOG语言实现的数据加密标准代码,在QUARTUS5.1上仿真过-Using Verilog language code of the Data Encryption Standard, in the simulation had QUARTUS5.1

应用背景这个补丁增加了GOST R 34.10-2012和 ；34.11-2012支持OpenSSL 1.0.2d。它是俄罗斯的加密标准。路径被发现在网络和应用OpenSSL最近的来源。关键技术OpenSSL 1.0.2d，GOST 34.10-2012数字签名，GOST 34.11-2012哈希（消息摘要），俄罗斯的加密标准，公钥密码体制，椭圆曲线密码体制。

base64编码-base64 encoding

写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但.ENC引伸。-Write an exclusive-OR encryption program. The program should take as input a filename that is then encrypted by the program. The program should ask the user to input an encryption key, which should be used to encrypt the file. The output of the program should go into a file with the same filename but a .ENC extension.

DES的实现，平时上课的实验，供大家参考。-DES implementation, usually in class experiments, for your reference.

LINUX下使用Ansi C编写的MD5消息散列算法-LINUX use Ansi C prepared news MD5 hash algorithm

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler

本包内容包括信息系统安全工程课程中的密码学基础、公钥加密与RSA、分组密码与DES共3个章节的内容，原汁原味的老师课堂讲义~包你喜欢~~！-This package includes information systems security engineering curriculum-based cryptography, public key encryption and RSA, block cipher with DES a total of three sections, authentic classroom teacher handouts ~ package you like ~ ~!

这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入。-This is an easy to use the MD5 of the C++ Category this category can be added to the console program can also be used in MFC, and it provides a detailed error handling function, is a safe type. MD5 is a routine procedure of MFC to support the two input strings and documents.
