CRC calculation
Or in hex and binary:
0x 01 04 C1 1D B7

What is the difference between NULL, '\0' and 0?
... zeroes).
string context - the character representing the digit zero has a hex value of 0x30, whereas the NUL character has hex value of 0x00 (used for terminating strings).

NULL - 0x00000000 or 0x00000000'00000000 (32 vs 64 bit)
NUL -...
