Simple CRC32 C-code. Here is a simple implementation of the commonly used CRC32 checksum using the reverse polynomial 0xEDB88320. The algorithm is consistent with setting of all bits in the initial CRC, along with negation of the bit pattern of the final running CRC.

When sending data, short checksum is generated based on data content and sent along with data. When receiving data, checksum is generated again and compared with sent checksum. CRC32 is an error-detecting function that uses a CRC32 algorithm to detect changes between source and target data. The CRC32 function converts a variable-length string into an 8-character string that is a text representation of the hexadecimal value of a 32 bit-binary sequence. Crc32 — Reverse lookup, unhash, and decrypt CRC (32 bit) is Cyclic redundancy check A CRC is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. For IEEE802.3, CRC-32. Think of the entire message as a serial bit stream, append 32 zeros to the end of the message.

Auto Update 2016/03/09: Fixed a bug: Sometimes a CRC32 result value was printed with only seven digits! A zero was then missing, e.g. the printed result was 0xC6FF2F8 instead of the correct one 0xC6FF02F8. Thanks to David Goodman for pointing the issue to me.

About CRC32 hashes In general a CRC can be n-bits in length, but most commonly a 32-bit CRC is used. An n-bit CRC has the property that any error run of up to n bits is mathematically guaranteed to produce a distinct CRC checksum.
