Definition
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols designed to provide secure communication over a computer network. While SSL is the older protocol, it has been largely replaced by TLS, which offers enhanced security features. Both protocols encrypt the data transmitted between a client (such as a web browser) and a server, ensuring that sensitive information is protected from interception or tampering.
Function
The main function of SSL/TLS encryption is to secure data in transit, making it difficult for unauthorized parties to eavesdrop on the communication. This encryption helps to protect sensitive information, such as usernames, passwords, and credit card details, from cybercriminals. Additionally, SSL/TLS provides authentication of the communicating parties and ensures data integrity, confirming that the data has not been altered during transmission. Websites that utilize SSL/TLS typically display "https://" in their URLs, indicating they are secured.
