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 via the dynamsoft-barcode-reader-bundle package, which requires a license key.

Installation

pip install dynamsoft-barcode-reader-bundle

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

import argparse
from sadl import *
import sys
import os

def sadltool():
    
    parser = argparse.ArgumentParser(description='Decode, decrypt and parse South Africa driving license.')
    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:
        args = parser.parse_args()
        source = args.source
        types = args.types
        if args.encrypted == 1:
            encrypted = True
        else:
            encrypted = False
        license = args.license
        
        if not os.path.exists(source):
            print('Source not found')
            exit(-1)
            
        if types == 1:
            dl = parse_file(source, encrypted, license)
            print(dl)
        elif types == 2:
            with open(source, 'r') as f:
                source = f.read()
                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)
