一种国际上通用的加密算法―DES算法的原理-a common encryption algorithms-DES algorithm Principle

使用的是API编程,可格式化、校验和读写特殊扇区。可用作Windows下的磁盘加密。本函数还有以下两个缺点以待改进： 1.本函数还只能读能读 A: 和 B:,即只能对软盘操作 2.不能改变磁盘扇区大小，只能是标准的 512 个字节。 参数说明: command 操作: 0 重置磁盘 2 读扇区 3 写扇区 4 校验磁道 5 格式化磁道 8 得到设备参数 (int 1EH) drive 驱动器 A:=0 B:=1 head 磁头号,范围 0 - 1 track 磁道号,范围 0 - 84 ( 80 - 84 为特殊磁道，通常用来加密 ) sector 扇区号,范围 0 - 255 ( 19 - 255 为非标准扇区编号，通常用来加密) nsectors 每次读或写的扇区数,不能超出每磁道的最大扇区数 buffer 数据写入或读出的缓冲区，大小为 512 个字节 返回值 ( 同 Int 13H ): 0x0 成功 0x1 无效的命令 0x3 磁盘被写保护 0x4 扇区没有找到 0xa 发现坏扇区 0x80 磁盘没有准备好-using the API programming, formatting and testing literacy and special sectors. Windows can be used as a disk encryption. This function has the following two shortcomings to be improved : 1. This function can only be read, read A : and B : that only the right to operate two floppy disks. No change disk sector size, the standard is only 512 bytes. Parameter Description : command operations : 0 Reading 2 replacement disk write Sector Sector 3 4 5 checksum track to be formatted track eight equipment parameters (int 1EH) drive drive
