SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols designed to secure internet communications by encrypting data between users and servers. TLS is the modern, more secure version of SSL, providing stronger encryption and authentication mechanisms.
How SSL/TLS Works
- Handshake Process - The client and server establish a secure connection by verifying identities and exchanging encryption keys.
- Encryption & Authentication - Data is encrypted during transmission to prevent interception by hackers.
- Data Integrity - Ensures that the transmitted data is not altered or tampered with.
Why SSL/TLS Matters
- Protects Sensitive Data - Encrypts login credentials, payment details, and personal information.
- Enables Secure Web Browsing - Websites with HTTPS use TLS to ensure encrypted communication.
- Compliance & Trust - Essential for meeting regulations like GDPR, HIPAA, PCI DSS, and maintaining user trust.
Common Use Cases of SSL/TLS
- Website Security (HTTPS) – Protecting users' data and preventing man-in-the-middle attacks.
- Email Encryption – Securing emails during transmission.
- Financial Transactions – Encrypting online banking and payment processing.
