This implementation allows using any custom polynomial. The crc32_generate() function first generates a polynomial-derived table for faster CRC-32 computation. This source code is in the public domain. You may use, share, modify it freely, without any conditions or restrictions. Online implementation of CRC-32 (Cyclic Redundancy Check) algorithm. Easily calculate CRC32 checksum and find related resources.

CRC The following example program shows how to compute a CRC byte in the C language. The outer loop processes each byte, and the inner loop processes each bit of those bytes. In the example main() routine, this is applied to generate the CRC byte in the message 0x83, 0x01, that was used in Section 6.5.

If we call the above polynomial p, and represent a byte as the 00026 polynomial q, also with the lowest power in the most significant bit (so the 00027 byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, 00028 where a mod b means the remainder after dividing a by b. 00029 00030 This calculation is done using the shift Source code for computing CRC32 and SHA1 checksum.
