-crcmod.predefined defines some well-known CRC algorithms.
-
-To use it, e.g.:
- import crcmod.predefined
-
- crc32func = crcmod.predefined.mkPredefinedCrcFun("crc-32")
- crc32class = crcmod.predefined.PredefinedCrc("crc-32")
-
-crcmod.predefined.Crc is an alias for crcmod.predefined.PredefinedCrc
-But if doing 'from crc.predefined import *', only PredefinedCrc is imported.
