linux下文件过滤驱动程序，可以实现在linux内核态下加解密的速度比应用层翻一倍。-the file filter driver linux, linux kernel can be achieved in the state than the speed of encryption and decryption application layer double.

c语言程序、文件加密、解密操作，C语言配置文件操作，文件读写、修改操作(C language program, file encryption and decryption)

aes加密、解密，直接包含头文件使用即可(AES encryption, decryption. Directly containing the header file can be used)
