What is TLS and why is it important?
At their core, TLS and SSL work by encrypting data transmitted between a user's device - phone, laptop or tablet - and the hosting server whicich has requested or is receiving that information.
This essential encryption ensures that any data exchanged – whether it's personal information, credit card numbers, or just casual messaging – is unreadable to anyone who might attempt to intercept it.

How is this achieved?
The process involves a digital "handshake" mechanism where the client (user) and server establish a secure connection.
Hence both sides MUST agree on encryption methods AND confirm authenticatiuon - BEFORE any sensitive data is transmitted.
A key component of TLS/SSL is the use of certificates. A website with TLS/SSL has a certificate issued by a trusted authority, verifying the website's identity. When you visit a secure website (indicated by HTTPS in the URL), your browser checks this certificate to ensure it's valid and the site is authentic, not a fraudulent one.
The importance of TLS/SSL can't be overstated in today's digital age:
Security: They protect sensitive data from being stolen or tampered with by hackers and cybercriminals.
Trust and Credibility: Websites using TLS/SSL are marked as secure in web browsers, building trust with users.
Data Integrity: They ensure that the data sent and received is not altered or corrupted during transmission.
Authentication: Certificates help in verifying that users are communicating with the intended website and not a malicious impersonator.
SEO and Performance: Search engines favor HTTPS-enabled websites, and secure connections can improve website loading times due to the latest web technologies being optimized for HTTPS.
In summary, TLS and SSL are crucial for ensuring a secure, trustworthy, and efficient online experience for both website owners and their users.
