This is the CRC16 algorithm used by Redis Cluster to hash keys. Implementation according to CCITT standards.

This is actually the XMODEM CRC 16 algorithm, using the following parameters:

Name : “XMODEM”, also known as “ZMODEM”, “CRC-16/ACORN” Width : 16 bit Poly : 1021 (That is actually x^16 + x^12 + x^5 + 1) Initialization : 0000 Reflect Input byte : False Reflect Output CRC : False Xor constant to output CRC : 0000 Output for “123456789” : 31C3
