汇编程序写的Hash校检程序，分享源码，支持SHA1和MD5两种，支持拉拽，支持剪切板的复制和比对，有进行条，自动计算耗时 （使用了不太精确的计时器），速度还是可以的，大概就这样。 

程序实现了大素数的判断和如果不是素数，则其可分解的最小的素数-program of large prime numbers and if the judgment is not prime, then decomposition of the smallest prime number

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

这个是基于混沌的AES加密算法-Chaos AES encryption algorithm

ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomposed into sub-blocks with a given size, and an external secret key with 192-bit is used and mapped to the system parameters, which are employed to generate a spatiotemporal chaotic binary sequence matrix to encrypt the block original image. Besides, the former sub-block encrypted result will be acted as a feedback to the following sub-block encryption proc- ess. The proposed scheme is described in detail, along with the security analyses such as key space analysis, sensitivity analysis, information entropy analysis and correlation coefficients analysis of adjacent pixels. The computer simulation results indicate that the suggested image encryption scheme has some properties desir- able in a good security
