Merging backend code (Java and Python) into HTML for seamless integration

While I have a solid background in back-end coding languages like Java and Python, the task at hand requires integrating this code into a website.

The backend code comprises various methods and classes to encrypt text messages using encryption techniques like AES. The focus now is to implement this system on a web platform.

After researching and consulting with others, it appears there are ways to incorporate Python or Java code into a webpage without translating it to PHP. Platforms like Django have been suggested, though I'm still unsure of the best approach for this particular project.

The website's main functions will include:

  1. User selection of encryption type, inputting a key, and message submission.
  2. Encrypting the message based on the selected key and encryption method.

If the encryption methods are already set up, how can I link user input on the webpage (text fields, drop-down menus, button clicks) to my program to execute the necessary functions and showcase the results?

I believe this can be achieved, but I am deliberating on the optimal choice for this task.

Thank you.

It is important to keep in mind that data transmitted from the user's browser to your server must travel over the Internet before reaching its destination. If you wish to encrypt this data while it is in transit, setting up a certificate and using HTTPS is necessary regardless of the programming language you choose.

In the case of Java, you would utilize a servlet container like Apache Tomcat to create a Servlet (a class that extends HttpServlet). Within the doPost() method of the Servlet, which receives user data, you can call your methods and display the message in HTML format surrounded by <html>, <body>, <p> tags.

To complete this setup, you would also need to design a simple HTML form containing options for encryption and a text area for entering data. The form should direct to the Servlet mentioned above, which will handle the encryption process.

The Servlet and HTML file should be packaged into a webapp war file and deployed within Tomcat.

While there are more intricacies involved, these key concepts should help you begin building a basic web application with a Servlet component.

A similar approach likely exists for Python as well, so don't hesitate to search for resources online!
