SSL/TLS encryption protocols are fundamental for secure internet communications, safeguarding data from eavesdropping and ensuring data integrity. These protocols, including TLS 1.2 and TLS 1.3, authenticate server identities and encrypt data, making online transactions safe. SSL/TLS certificates from CAs provide additional trust and security, indicating a verified and secure connection to users.

SSL 2.0 was quickly replaced by SSL 3.0 due to significant security weaknesses
TLS Protocol
The TLS protocol was introduced as an improvement over SSL 3.0, offering stronger security features
TLS 1.2
TLS 1.2 is the most prevalent version, providing robust security measures against cyber threats
TLS 1.3
TLS 1.3 further improves security by reducing the complexity of the handshake process and removing outdated cryptographic features
SSL/TLS certificates are digital credentials that link a cryptographic key to an organization's identity, serving to authenticate the identity of a website and secure data in transit
The SSL/TLS handshake is a series of steps that establish a secure connection between a client's browser and a web server
During the handshake, the browser verifies the server's SSL/TLS certificate to ensure trust
The browser and server agree on encryption parameters to create a unique session key, which is used to encrypt all data exchanged during the session
SSL/TLS encryption authenticates the identity of the server and optionally the client
SSL/TLS encryption encrypts data to prevent eavesdropping
SSL/TLS encryption ensures the integrity of transmitted data, protecting against data tampering
SSL/TLS encryption is essential for securing data transmission over the internet and protecting against cyber threats
SSL/TLS encryption builds user trust by verifying the legitimacy of websites and encouraging secure online transactions
SSL/TLS encryption is crucial for meeting regulatory compliance and protecting against data breaches

SSL/TLS Key Pair Function
Public key encrypts messages to server; private key decrypts received messages.
01
SSL vs TLS - Relationship
TLS is the successor to SSL; both protocols secure communications but TLS is more advanced.
02
SSL/TLS in Data Protection
Ensures sensitive data like credit card numbers and login credentials remain private during transmission.
