DES_C

文件加密器,实现对文件加密,用来学习的代码(File encryption, encrypting files, the code used to study)

说明：  获取硬盘物理序列号,用来对软件加密，vs2008工程。(HD number)

1、 所有密钥的装载与导出都采用密文方式； 2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制； 3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理； (1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )

计算卡片过程密钥，加密密码数据，计算安全报文鉴别（MAC）过程密钥 (Calculating card key, the encrypted password data, calculate the safety message authentication (MAC) key)

通过MATLAB的编程，实现对图片的加密，奇异值的分解，离散变化，程序简单，明了。(Through MATLAB programming, realize the image encryption, singular value decomposition and discrete changes, procedure is simple, clear.)

采用c++实现RC4加密解密算法，该代码可以加密解密任意格式的文件( U91C7 u758ccc_cn R U6587 u4EF6)

PF140.514版digsilent软件的两个破解文件，按一定操作步骤即可免狗驱动，本人已在XP环境下使用，没有问题。希望对采用该软件的人有一点帮助！(Two crack file PF140.514 the version digsilent software, Free Dog certain steps to drive, I have XP environment, there is no problem. I hope the software a little help!)

使用MD5算法对数据和文件进行加密，信息安全(Using the MD5 algorithm to encrypt the data and documents, information security)

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)

将天骄2服务端的加密文本文件与生成的软件放在同一目录下,点击批量转换, 完成后会在同目录下生成一个名为temp的文件夹,其中存放的就是转换后的文件. 因为加密和解密的规则完全相同,所以加密过程和解密过程相同, 也就是说如果原来的文件存放的是原文,转换后就会生成密文,如果原来是密文,转换后生成原文. 适用于天骄2,凤舞天骄的所有版本服务端.(The the Tianjiao 2 server encrypted text file in the same directory with the generated software, click on the batch conversion finished, it will generate a folder named temp in the same directory, which store the converted file encryption and decryption rules are identical, so the encryption and decryption process is the same, that is to say if the original file is stored in the original conversion will generate the ciphertext, if the original ciphertext, conversion generated text. apply to tianjiao, all of Fung Mo tianjiao, the version of the server.)
