Transport Layer Security (TLS/SSL) is essential for secure internet communication, utilizing encryption, authentication, and data integrity. Common use cases include financial transactions, e-commerce, and email, which require protection of sensitive information. As HTTPS becomes more prevalent, users can trust that their data is safeguarded from external threats.

4. How Does TLS Work?
Handshaking
First, the client and server exchange messages to agree
on a shared encryption key.
Encryption
Next, all data sent between the two parties is encrypted
according to the agreed-upon algorithm.
Verification
The server presents a digital certificate to prove its
identity to the client, which verifies the certificate's
authenticity.
Targeting
Finally, the two parties can communicate with each other
over a secure channel, safe from external attacks like
Man-in-the-Middle (MITM) attacks.

6. Benefits of Using HTTPS with TLS/SSL
1
Encryption
HTTPS uses encryption to protect data from being
intercepted during transmission.
2
Authentication
HTTPS ensures the authenticity of the website you visit
and the data you receive.
3
Integrity
HTTPS verifies that the data received is the data that was
sent, without being manipulated or changed during
transmission.

9. Common Use Cases for TLS/SSL in Web
Applications
Financial Transactions
Online banking and financial
transactions require secure
communication to protect sensitive
information like account numbers and
passwords.
E-commerce
Online stores and marketplaces use
SSL/TLS to protect customers'
personal data such as credit card
numbers, shipping addresses, and
phone numbers.
Email
TLS can be used to secure email
communication by enabling encryption
between email servers.

12. Conclusion
Transport Layer Security (TLS) plays a crucial role in ensuring secure
communication over the internet. With the adoption of HTTPS becoming
more widespread and TLS protocols evolving, online users can trust that
their data is protected from external threats when communicating over the
web.
