Python Decoder for Driving License in South Africa
The Python project is used to decode, decrypt and parse South African driving licenses. The PDF417 decoding part relies on Dynamsoft Barcode Reader, which requires a license key.
Command-line Usage
$ sadltool [-t TYPES] [-e ENCRYPTED] [-l LICENSE] source
positional arguments:
source A source file containing information of driving license.
options:
-h, --help show this help message and exit
-t TYPES, --types TYPES
Specify the source type. 1: PDF417 image 2: Base64 string 3: Raw bytes
-e ENCRYPTED, --encrypted ENCRYPTED
Is the source encrypted? 0: No 1: Yes
-l LICENSE, --license LICENSE
The license key is required for decoding PDF417
Try Project Examples:
python test.py images/dlbase64.txt -t 2 -e 0
python test.py images/dl.raw -t 3 -e 0
python test.py images/dl.png -l <Dynamsoft Barcode Reader License Key>
Sample Code

parser.add_argument('source', help='A source file containing information of driving license.')
parser.add_argument('-t', '--types', default=1, type=int, help='Specify the source type. 1: PDF417 image 2: Base64 string 3: Raw bytes')
parser.add_argument('-e', '--encrypted', default=1, type=int, help='Is the source encrypted? 0: No 1: Yes')
parser.add_argument('-l', '--license', default='', type=str, help='The license key is required for decoding PDF417')
if len(sys.argv) == 1:
parser.print_help()
sys.exit(1)
try:

if args.encrypted == 1:
encrypted = True
else:

exit(-1)
if types == 1:

print(dl)
elif types == 2:

dl = parse_base64(source, encrypted)
print(dl)
elif types == 3:
data = Path(source).read_bytes()
dl = parse_bytes(data, encrypted)
print(dl)
except Exception as err:
print(err)
sys.exit(1)
