计算校验和
校验和算法描述:为保证网络上传输的数据的可靠性,在许多协议中都设置了校验和项,例如:IPv4、ICMPv4、IGMPV4、ICMPv6、UDP和TCP 等等。计算这些校验和的算法称为网际校验和算法,简单来说就是:把被校验的数据16位进行累加,然后取反码,若数据字节长度为奇数,则数据尾部补一个字节的0以凑成偶数。
由于从输入文件读入的数据不能直接满足计算校验和的条件,所以首先对从文件读入缓冲区的数据进行预处理,即读入缓冲区时忽略空格。由于累加是按16位进行的,所以每次从缓冲区中读出4个字符,并将字符转换成对应的16进制数字,如此依次累加,直至数据全部读完。
还有一种情况,即如果数据长度为奇数个字节,则需要判断,并补0累加。程序中利用的是缓冲区长度计数器i和当前读取到计数器j判断数据长度是否为奇数。即如果数据长度为偶数,则读完数据时当前读取到计数器j的值应与缓冲区长度i相等,而如果数据长度为奇数,则读完数据时,当前读取到计数器j>缓冲区长度i,此时需将缓冲区中剩余的两个字符读出,并补0,转换成相应16进制数以后参与累加。
当累加结束后,将累加和的16位以上数据位移下再进行一次累加,并对最后累加和取反即得所求校验和。
-calculated checksum checksum algorithm Description : To ensure the network transmission of data reliability, in many of the agreements are set up and calibration, for example : IPv4, ICMPv4, IGMPV4, ICMPv6. UDP and TCP so on. Calculating checksum algorithm called the Internet checksum algorithm, the simple answer is : as has been the calibration data for 16 cumulative, and then take the anti-code, if the data byte length of the odd, data will make up the tai
