ndk学习笔记C语言文件加解密

       //文件加密

void encode(char normal_path [],char encode_path []){

		FILE * normal_fp = fopen(normal_path, "r");
		FILE * encode_fp = fopen(encode_path, "w");
		
		int ch;

		while ((ch = fgetc(normal_fp))!=EOF)
		{
			fputc(ch ^ 7, encode_fp);
		}

		fclose(normal_fp);
		fclose(encode_fp);
	}

   //测试

void main() {

		char * normal_path = "F:\\open.txt";
		char * encode_path = "F:\\openone.txt";
		char * decode_path = "F:\\opendecode.txt";

		//encode(normal_path, encode_path);
		decode(encode_path, decode_path);
		system("pause");
	}

//解密
