这是一个手机编程和邮件编程常用到的一个编码技术函数，Base64编码和解码动态库，支持字符串和文件的编解码工作。速度很快稳定，我的一些程序中用，现在发布。-This is a cell phone programming and e-mail program into a coding techniques commonly used functions, Base64 encoding and decoding of dynamic libraries, and documentation to support the string of codecs. Fast stable, I am using some of the procedures, now released.

一篇数字水印方面的文章。-a digital watermark articles on the subject.

The Advanced Encryption Standard (AES) specifies a FIPS- approved cryptographic algorithm that can be used to protect electronic data.  The AES-128 pipelined cipher module uses AES algorithm which is a symmetric block cipher to encrypt (encipher) information. This module is optimized for speed as it pipeline hardware to perform repeated sequence called round

在原作者Jim Gillogly代码的基础上修改优化，并实现C++改写。实现了DES加密。当然，密钥可在源文件中修改，或提供修改的接口函数。-the originator Jim Gillogly code revision on the basis of optimization, and to achieve C rewritten. Implementation of DES encryption. Of course, the key in the source documents changes, or amendments to provide the interface function.

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
