python crc32有两种校验.第一种是assii码校验第二种是16进制校验.

def crc32asii(v):
return '0x%8x' % (binascii.crc32(v) & 0xffffffff)
def crc2hex(crc):
return '%08x' % (binascii.crc32(binascii.a2b_hex(crc)) & 0xffffffff)
s='1234567890'
b = bytes(s, encoding='utf-8')
print(crc32asii(b))
#1234567890的16进制为499602D2
d='499602D2'
print(crc2hex(d))
