ioprox Card Numbers to Proxmark Hex Data

ioprox_encode.py

# Encodes ioprox data to format used by proxmark, if using a version that doesn't allow you to specify
# the version/facility/cardnumber seperately.

version = id_str.split('(')[1].split(')')[0]
facility = id_str.split('(')[1].split(')')[1].split(':')[0]
code = id_str.split(':')[1]

version = int(version, 16) #is this hex? Have only seen 1 or 2 here
facility = int(facility, 16) #this is always hex
code = int(code, 10) #this is always decimal

checksum = 0xF0 + facility + version + (code >> 8) + (code & 0xff)
checksum = 0xFF ^ (checksum & 0xff)

interesting, sim vs clone doesn't allow for raw vs vn/fc/cn inputs. That would be a nice addition

lf io sim
lf io clone
