Seed加密体制代码，韩国的分组密码加密体制。(Seed encryption system code block cipher encryption system in Korea.)

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.)

windows登陆密码信息拦截，获取明文口令。程序对不同系统做了处理，在2000,2003,xp,vista上都可以截取， 在2000,2003,xp中，通过UNICODE_STRING.Length 的高8位取xor key,如果密码是编码过的，则通过ntdll.RtlRunDecodeUnicodeString解码， vista则通过AdvApi32.CredIsProtectedW判断密码是否编码过，解码用AdvApi32.CredUnprotectW。(The windows Password intercept, access to the plaintext password. Processing program on a different system in 2000, 2003, xp, vista can intercept, 2000,2003, xp UNICODE_STRING.Length high eight take xor key if the password is encoded by the ntdll.RtlRunDecodeUnicodeString decoding, vista, to judge by AdvApi32.CredIsProtectedW and password whether encoding, decoding AdvApi32.CredUnprotectW.)

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

支持椭圆曲线运算的大数运算库和源程序，头文件和静态库可以使用。(Support for elliptic curve operations of large numbers arithmetic library and source code, header files and static libraries can be used.)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

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.)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

基于CUDA的AES快速加密解密文档，系统介绍饿AES算法的设计与优化(CUDA-based AES encryption and decryption of documents quickly, the system introduced hungry AES algorithm design and optimization)
