Does anyone have the code and test vectors to CRC-24 Radix64 (from RFC4880)? Either the code i have is wrong, or I dont know how to input the data. i cant seem to find a source code from other programs. is this code even correct?
def CRC24(octets):
# octets is a binary string
# 0xabcd -> '1010101111001101'
# the octet value comes from the ascii data, not the radix 64 data
# read as ascii
INIT = 0xB704CE
POLY = 0x1864CFB
crc = INIT
for octet in octets:
crc ^= (int(octet) << 16)
for i in xrange(8):
crc <<= 1
if crc & 0x1000000:
crc ^= POLY
return crc & 0xFFFFFF
