When a user initiates a transaction, the browser connects to the server using HTTPS, and the first step is the SSL/TLS handshake. This process establishes a secure connection between the client and the server.

2. Digital Certificates

The server presents a digital certificate that verifies its identity. This certificate is issued by a trusted Certificate Authority (CA). The browser checks the validity of this certificate before proceeding, ensuring users are connected to legitimate sites.

3. Session Keys Generation

After successful authentication, both the client and server generate unique session keys for encryption. This ensures that even if one session key is compromised, it cannot be used in subsequent transactions.

4. Encrypted Data Transmission

With established session keys, the transaction data, including payment information, is encrypted and transmitted securely. This means that even if the data is intercepted, it remains unintelligible without the decryption key.

5. Data Integrity Verification

Alongside encryption, SSL/TLS provides data integrity checks. This means that the data sent and received during the transaction is verified to ensure it has not been altered in transit.

“SSL/TLS doesn't just encrypt data; it also provides authentication and ensures data integrity, making it vital for secure online payments.”
