TLS and SSL are cryptographic protocols to secure sensitive information transmitted between browsers and servers. These cryptographic protocols allow sensitive information such as credit card numbers, social security numbers, and login details to be transmitted in an encrypted form.
Without SSL/TLS, data transmitted between the browser and server is sent in plain text, which is vulnerable to eavesdropping. Network attackers can easily intercept information transmitted in plain text.
SSL (Secure Socket Layer)
SSL communication protocol was designed in 1996 to provide privacy and reliability between two servers or applications. SSL prevents attackers from compromising the sensitive information traveling between servers or client and server.TLS (Transport Layer Security)
The main difference between SSL and TLS is as below:
SSL connections begin with security and proceed directly to secured communications. Whereas TLS connections begin with an insecure “hello” to the server and only switch to secured communications after the handshake between the client and the server is successful. If the TLS handshake fails for any reason, the connection is never created. The exact differences between SSL-TLS are extremely technical, but in simpler words, we can say that TLS is the latest and more refined cryptographic technology.
