得到大素数的算法的Pascal源码 - Obtains the big prime number the algorithm Pascal source code

这个是基于混沌的DES算法-this is based on the DES algorithm Chaos

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

Serpent加密算法源代码-Serpent encryption algorithm source code

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

RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.

openssl编程入门(含完整示例),是一本openssl安全编程的一本入门书，相当不错、！-openssl programming entry (including a complete sample), is a security program openssl an entry book, quite good!
