使用c语言设计的加密算法,直接对文件流加密.用vc++做的使用界面-use encryption algorithm design, direct flow of the document encryption. Vc done with the user interface

用C++编写的流密码算法。从文件读入明文，并将密文写到指定文件。所有源文件齐备，保证测试通过。-Written in C++, stream cipher algorithm. Read from a file into the plaintext and ciphertext writes the specified file. All source documents are to ensure the test.

仿射变换加密的c语言实现，采用文件流载入明文，密文问件，解密出来的明文默认保存在mword.txt里，密文保存在cword.txt里-Affine transformation encryption c language, using plain text file stream to load the ciphertext asked pieces out of plain text to decrypt stored in mword.txt default, the cipher text

流密码RC4的加密解密文件的C++算法，可以静态加密文件也可以动态加密-C++ stream cipher RC4 algorithm for encryption and decryption of files, you can still encrypt files can also be dynamic encryption
