CRC Checksum Generator (CRC32)

CRC32 (Cyclic redundancy check) is a 32 bit hash function (a one-way hashing algorithm) used mainly to detect accidental changes during data transmission. If the computed CRC checksum is different from the original CRC checksum, then there has been an error in the transmission. It's often used in networks and hard disk drives. The CRC was invented by W. Peterson and published in 1961.

The above CRC32 Checksum generator converts a string into a CRC checksum. For example, if you type:
"CRC32 Checksum"
in the input field above and submit you get a digit:
25790390.
But even a small change in the text will result in a completely different CRC32 checksum. For example, if you type:
"CRC32 checksum"
and submit form then you get a completely diffrent CRC checksum:
042b73cf.
