Since the CRC calculates a value after the data is calculated, this value is relatively small in ordinary applications. So you can use the index of some character data. However, the initial string is used in the CRC in C and Perl, but the resulting value is not correct. Using the String :: CRC package in Perl5.8.4, use the string :: CRC32 package. And Printf String :: CRC32 :: CRC32 (: "Hello") will result in the same value as C. If you need to discuss, please use the mail conquer@vip.sina.com
