Overview

The Password Generator uses a multi-layered random selection algorithm to create secure, unique passwords. The system generates 50 candidate passwords and randomly selects one to ensure unpredictability.

​
Algorithm Details

The password generation algorithm is implemented in password_generator.py and uses three core components:

​
Character Set Components

Numbers

Random selection from a range of 51-4000 numbers, with 50 unique numbers chosen

Alphabetic Characters

Lowercase letters a-z, with 5 unique characters selected per password

Special Characters

36 special characters including !, @, #, $, %, &, and international symbols like €, ¡, ¿

​
Generation Process

The password_generator() function creates passwords using the following pattern:
password_generator.py:62
password = f"{random.choice(list_char)}{random.choice(list_num)}{random.choice(list_str)}{random.choice(list_char)}{random.choice(list_str).upper()}{random.choice(list_str)}{random.choice(list_num)}{random.choice(list_str)}{random.choice(list_str)}{random.choice(list_char)}"
This generates a 10-character password with:
  • Position 1: Special character
  • Position 2: Number
  • Position 3: Lowercase letter
  • Position 4: Special character
  • Position 5: Uppercase letter
  • Position 6: Lowercase letter
  • Position 7: Number
  • Positions 8-9: Lowercase letters
  • Position 10: Special character
The algorithm generates 50 unique password candidates and randomly selects one, ensuring each password is truly random and collision-resistant.

​
Character Set Customization

The character sets are defined in the password() function:
password_generator.py:82-90
num = list_elements(random.randint(51, 4000))
num = num.select_num()

alphabet = list_elements(list("abcdefghijklmnopqrstuvwxyz"))
alphabet = alphabet.select_char()

char = list_elements(['!', '"', '#', '$', '%', '&', "'", '(', ')', '*', '+', ',', '-', '.', '/', ':', ';', '<',
                      '=', '>', '?', '@', '[', ']', '^', '_', '`', '{', '|', '}', '~', "¡", "¿", "¿", "¡", "°", "€"])
char = char.select_char()

​
Element Selection Classes

The list_elements class provides two selection methods: Number Selection (password_generator.py:12-24): 
def select_num(self):
    list_num = list(range(self.element))
    list_num = random.sample(list_num, 50)
    return list_num
Character Selection (password_generator.py:26-41): 
def select_char(self):
    chars = []
    for i in range(5):
        char = random.choice(self.element)
        chars.append(char)
    return list(set(chars))

​
Usage Examples

​
Python Console Version

Generate a password directly using the Python module: 
from password_generator import password

# Generate a secure password
new_password = password()
print(new_password)  # Example output: !42a#Bc7de€

​
Web API Version

The web application provides a REST API endpoint to generate passwords: Endpoint: GET /api/password/generate/ Request: 
curl -X GET http://localhost:8000/api/password/generate/
Response: 
{
  "output": "!42a#Bc7de€"
}
Implementation (views.py:16-27): 
@api_view(['GET'])
@permission_classes([AllowAny])
def response_password(request):
    try:
        result = password()
        
        if isinstance(result, str) == False:
            return Response({"Error in script": result}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)
        
        return Response({"output": result}, status=status.HTTP_200_OK)
    except Exception as e:
        return Response({"error": str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)
The password generation endpoint is publicly accessible (AllowAny) and does not require authentication.

​
Frontend Integration

The React/Next.js frontend provides a button component for password generation:
ButtonGeneratePassword.jsx:12-20
const handleOnClick = async () => {
    try {
        const newPassword = await getGeneratePassword();
        setPassword(newPassword);
        onReturnPassword(password);
    } catch (error) {
        console.error("Error getting password:", error);
    }
};

​
Security Considerations

While the algorithm generates strong passwords, ensure you:
  • Use HTTPS in production to transmit passwords securely
  • Never log generated passwords
  • Store passwords using proper hashing (bcrypt, Argon2, etc.)

​
Password Strength

Generated passwords have:
  • Length: 10 characters
  • Character diversity: Numbers, lowercase, uppercase, and special characters
  • Entropy: High randomness from multiple selection pools
  • Pattern resistance: Random positioning prevents predictable patterns

​
Error Handling

The generation functions include comprehensive error handling:
password_generator.py:69-71
except Exception as e:
    return print(f"Error generating password -> {e}")
Common error scenarios:
  • Insufficient random data
  • Invalid character set configuration
  • Memory constraints during generation
For custom password requirements, modify the character sets in the password() function or create wrapper functions with specific configurations.
