"Web20 mei 2011 · A proper CRC library is probably your best bet, but just for potential interest: rather than XORing the bits in your values, you can use each byte (i.e. an *(uint8_t*)& reinterpretation) to index into a table of say 32-bit random numbers, then XOR those table entries together. This means a single bit of variation in a value randomly flips bits in the … " - Is a crc a checksum
