How to Make Money By Creating URL Shortner.

A URL shortener is a service that takes a long URL and converts it into a shorter, more concise URL that redirects to the original URL when clicked. URL shorteners are often used to share links on social media platforms or to make long links more aesthetically pleasing or easier to remember.

For example, a long URL like "" might be shortened to "" When someone clicks on the shortened URL, they will be redirected to the original URL.

URL shorteners often use a combination of letters and numbers to create the shortened URL. They may also use a custom domain name to make the shortened URL more memorable or recognizable. Some URL shorteners also offer additional features, such as the ability to track the number of clicks on the shortened URL or to customize the appearance of the shortened URL.

Here is a simple example of how you might create a URL shortener using Python:

  1. First, you will need to import the necessary libraries. For this example, you will need the base64 library to encode and decode the original and shortened URLs, and the hashlib library to create a hash of the original URL:
Copy codeimport base64
import hashlib
  1. Next, you will need to create a function to generate the shortened URL. This function should take the original URL as input and return the shortened URL. To generate the shortened URL, you can first create a hash of the original URL using the sha256 function from the hashlib library. Then, you can encode this hash using the b64encode function from the base64 library. Finally, you can return the encoded hash as the shortened URL:
Copy codedef shorten_url(url):
    hash = hashlib.sha256(url.encode())
    shortened_url = base64.b64encode(hash.digest())
    return shortened_url
  1. You will also need to create a function to retrieve the original URL from the shortened URL. This function should take the shortened URL as input and return the original URL. To do this, you can first decode the shortened URL using the b64decode function from the base64 library. Then, you can compare the decoded URL with the hashes of all the original URLs in your database to find the matching original URL:
Copy codedef retrieve_url(shortened_url):
    decoded_url = base64.b64decode(shortened_url)
    for original_url, hash in database.items():
        if hash == decoded_url:
            return original_url
    return None
  1. Finally, you can use these functions to shorten and retrieve URLs as needed. For example:
Copy codeoriginal_url = ""
shortened_url = shorten_url(original_url)
print(shortened_url)  # Outputs the shortened URL

retrieved_url = retrieve_url(shortened_url)
print(retrieved_url)  # Outputs the original URL

This is just a simple example, and you may want to add additional features or error handling to your URL shortener. For example, you might want to store the original URLs and their hashes in a database, or you might want to handle cases where the shortened URL is not found in the database.
