纯C语言实现基于AES算法的加密，从文件每次读取16个字节加密后写入指定文件中，同时把源文件大小和密钥做异或写入加密文件中。-Pure C language based on the AES algorithm encryption, encrypted each read 16 bytes written to the specified file from the file, while the size of the source file and the key is to do XOR

纯C语言实现基于AES算法的解密功能，从用AES加密后的文件读取16个字节后，解密操作，同时读取加密文件的前四个字节，表示源文件的长度大小。-Pure C language implementation based on AES algorithm decryption functions, read 16 bytes from the file after using AES encryption and decryption operations, read the first four b

本程序使用C++语言在VC6.0下实现DES加密解密过程，输入明文从文件读取，输出密文写到文件，加密密钥程序内定，可以修改。-This program uses C++ language Under the VC6.0 DES encryption and decryption process, the input plaintext read from the file, the output ciphertext is written to the file encryption key p

多表代替密码的c语言实现。从文本文件读取进行加密变换-Multi-table instead of passwords c language. Read from a text file is encrypted transformation
