For the class names simply remove all dashes and slashes from the above names and apply CamelCase, e.g.
"CRC-32/MPEG-2" is implemented by ``Crc32Mpeg2``. Other CRC can be calculated by using the general class
``crccheck.crc.Crc`` by providing all required CRC parameters.
The ``crccheck.checksum`` module implements additive and XOR checksums with 8, 16 and 32 bit:
``Checksum8``, ``Checksum16``, ``Checksum32`` and ``ChecksumXor8``, ``ChecksumXor16``, ``ChecksumXor32``
Usage example::
from crccheck.crc import Crc32, CrcXmodem
from crccheck.checksum import Checksum32
# Quick calculation
data = bytearray.fromhex("DEADBEEF")
crc = Crc32.calc(data)
checksum = Checksum32.calc(data)
# Procsss multiple data buffers
data1 = b"Binary string" # or use .encode(..) on normal sring - Python 3 only
data2 = bytes.fromhex("1234567890") # Python 3 only, use bytearray for older versions
data3 = (0x0, 255, 12, 99) # Iterable which returns ints in byte range (0..255)
crcinst = CrcXmodem()
crcinst.process(data1)
crcinst.process(data2)
crcinst.process(data3[1:-1])
crcbytes = crcinst.finalbytes()
crchex = crcinst.finalhex()
crcint = crcinst.final()
