[jaythorat]

Description

This issue tracks the implementation of TLS Support to enhance the security of the DNS server.

TLS Support

Objective:

• Encrypt communication between the DNS server and clients using Transport Layer Security (TLS).

Benefits:

• Prevents eavesdropping and man-in-the-middle attacks.
• Builds user trust by ensuring data confidentiality and integrity.

Tasks:

• Use Python's ssl module to enable TLS.
• Obtain a trusted SSL/TLS certificate for the server.
• Implement DNS over TLS (DoT) or DNS over HTTPS (DoH).
• Configure the server to listen on a secure port (e.g., 853 for DoT).
• Add configuration options for enabling/disabling TLS.
