definition secure sockets layer ssl is a security protocol that provides privacy authentication and integrity to internet communications ssl eventually evolved into transport layer security tls share what is ssl what is an ssl certificate what is tls why use https what is https ssl glossary of terms what is mixed content keyless ssl ssl handshake public key encryption how ssl works asymmetric encryption what is encryption http security gaps ssl certificate types cryptographic key why use tls 1 3 what is a session key what is sni connection not private lava lamp encryption what is encrypted sni what is domain spoofing what is ssl what is ssl ssl or secure sockets layer is an encryption based internet security protocol it was first developed by netscape in 1995 for the purpose of ensuring privacy authentication and data integrity in internet communications ssl is the predecessor to the modern tls encryption used today a website that implements ssl tls has https in its url instead of http how does ssl tls work in order to provide a high degree of privacy ssl encrypts data that is transmitted across the web this means that anyone who tries to intercept this data will only see a garbled mix of characters that is nearly impossible to decrypt ssl initiates an authentication process called a handshake between two communicating devices to ensure that both devices are really who they claim to be ssl also digitally signs data in order to provide data integrity verifying that the data is not tampered with before reaching its intended recipient there have been several iterations of ssl each more secure than the last in 1999 ssl was updated to become tls why is ssl tls important originally data on the web was transmitted in plaintext that anyone could read if they intercepted the message for example if a consumer visited a shopping website placed an order and entered their credit card number on the website that credit card number would travel across the internet unconcealed ssl was created to correct this problem and protect user privacy by encrypting any data that goes between a user and a web server ssl ensures that anyone who intercepts the data can only see a scrambled mess of characters the consumer s credit card number is now safe only visible to the shopping website where they entered it ssl also stops certain kinds of cyber attacks it authenticates web servers which is important because attackers will often try to set up fake websites to trick users and steal data it also prevents attackers from tampering with data in transit like a tamper proof seal on a medicine container are ssl and tls the same thing ssl is the direct predecessor of another protocol called tls transport layer security in 1999 the internet engine...
