# Simulate a "rolling code" step hash_val = hashlib.sha256(combined).hexdigest()
# Extract first 8 chars as a mock incode (Ford incodes are often 6–8 digits) mock_incode = ''.join([c for c in hash_val if c.isdigit()])[:8] ford tis incode
For learning/demonstration, you could build a : # Simulate a "rolling code" step hash_val = hashlib
# Combine outcode and VIN (mock "seed") combined = f"{outcode}{vin}".encode() ford tis incode
