DES-complete

基于双缓冲过滤驱动的透明加密系统研究与实现(Based on double buffer transparent encryption system filter driver and Implementation Research)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

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)

3des加密解密,des加密解密该算法通过编译，可以直接使用。(3DES encryption and decryption algorithms.)

椭圆曲线密码体制及其在电子银行中的应用，对椭圆曲线的加解密应用具有很好参考价值(Elliptic curve cryptography and its application in e-banking, a good reference value of the elliptic curve encryption and decryption application )

使用DES算法；可以指定使用DES、2DES或者3DES算法；可以对任意的文件进行加密和解密，加密后文件扩展名为.des，可以指定使用ECB,CBC,CFB,OFB,CTR的任意一种模式； (The use of DES algorithm can specify the use of DES, 2DES or 3DES algorithm can arbitrary file encryption and decryption, encryption, named after the file extension. Des, you can specify the use of ECB, CBC, CFB, OFB, CTR arbitrary a model )

DES加密算法，初始置换、密钥置换、密钥循环、密钥压缩置换、数据扩展置换、、S盒替换、P盒置换、末置换 (DES encryption algorithm, the initial replacement, key replacement, key loops, key compression replacement, data expansion permutation,, S cartridge replacement, P cartridge replacement, replacement end)

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)

将国密算法SM3, SM4 ECB的C代码打包成dll库。 然后在C#中进行调用。 有输入输出接口，测试结果正确。 包含所有源代码，可在此基础上进一步开发(The C code of the Chinese national algorithm SM3, SM4 ECB is packaged into a dll library and then called in C# with input and output interfaces. The test result is correct. Contains all source code and can be further developed on this basis)

Rijndael加密算法的一个实现，可用来对文件及字段进行加解密，并利用mfc做了界面(An implementation of Rijndael encryption algorithm, can be used to encrypt and decrypt files and fields, and made use of the interface mfc)
