version")](https://hex.pm/packages/crc)

This module is used to calculate CRC (Cyclic Redundancy Check) values for binary data. It uses NIF functions written in C to interate over the given binary calculating the CRC checksum value.

CRC implementations have been tested against these online calculators to validate their correctness to the best of our ability.
