- 基于U盘的身份认证 现在市场上出现各种各样的基于硬件的加密设备，但应用于身份认证的还很少，大部分应用在软件产品的加密方面。 软件开发商在开发软件特别是行业软件时经常用到身份验证，传统当方式是采用用户名＋密码的方式进行认证，这样的验证方式存在很多缺点主要表现在以下两个方面： 1． 用户信息容易泄密 2． 用户信息容易遗忘 3． 给领导使用带来不便 作为软件开发商为了提高软件的可用性、加载身份认证功能。但需要从市场上加密厂商手中购买身份认证设备，但存在以下弊端： 1．

特殊磁道加密源代码
- 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
