CRC32 is small utility that is designed to calculate the 32 bit CRC and the MD5SUM for a file. A Cyclic Redundancy Check, or CRC, is a easy and very fast method to check whether a file has been damaged or changed. A CRC is a unique signature, belonging to only one file. Many programs check the CRC with the calculated CRC to make sure that the file has not been damaged or tampered with.

CRC32 is very easy to use. Simply type CRC32 followed by the name of the file. The CRC and MD5SUM values are returned, as it is stored in the .TIC files. The CRC is in hexadecimal format.
