WebCRC24 Hash works by performing a series of bitwise operations on the input data, using a polynomial function to generate a binary sequence, and applying the CRC algorithm to each chunk of the binary sequence to generate a 24-bit output. The bitwise operations involve XORing the input byte with a predefined value and shifting the result to the left.
