usage: crc32.py [-h] action ...
Reverse, undo, and calculate CRC32 checksums
positional arguments:
action
flip flip the bits to convert normal(msbit-first) polynomials to
reversed (lsbit-first) and vice versa
reciprocal
find the reciprocal (Koopman notation) of a reversed (lsbit-
first) polynomial and vice versa
table generate a lookup table for a polynomial
reverse find a patch that causes the CRC32 checksum to become a desired
value
undo rewind a CRC32 checksum
calc calculate the CRC32 checksum
optional arguments:
-h, --help show this help message and exit
