Hello,
I have been trying to adapt crcutil as a high-performance,
concatenation-capable cksum replacement. However, I notice that the crc32
generating polynomial used in crcutil is the "reverse form" polynomial,
0xEDB88320 (per Wikipedia terminology), not the "normal" form (0x04C11DB7)
commonly used. And while the CRC outputs from crcutil match those from BSD
"cksum -o 3", when I replace the generating polynomial with 0x04C11DB7 the
outputs don't match those from "cksum".
Any advice on what I'm doing wrong?
Thanks,
-ak
