This CRC calculator shall support hardware and software designers to check their specific CRC routine. Most of the theory for the JAVASCRIPT and the C code below is taken from the well-known PAINLESS GUIDE TO CRC ERROR DETECTION ALGORITHMS article written by Ross N. Williams. The calculator has the following features:

Auto Update This page provides a Javascript implementation CRC32 (Cyclic Redundancy Checksum) calculator. CRC32 (Cyclic Redundancy Checksum) is a fast and efficient algorithm to check the integrity of the data. It returns a 32-bit integer (signed or unsigned). It can be considered a weak type of Cryptographic hash functions (such as MD5). We added one more arithmetic operation (negation) and replaced the multiplication by AND. The lower latency of these two binary operations is the reason why the improved branch-free algorithm is the fastest (about 70 MByte/s) for bit-wise CRC calculation. The final code of crc32_bitwise: CRC8 calculator.

What I wanted to do was to understand how it is calculated. So what better way than to try and replicate a calculation by hand.

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. 2015/05/30: Initial release.
