ssl vs tls

The TLS handshake layer manages which cipher (the type of encryption algorithm) will be used, the authentication (using a certificate specific to your domain name and organization), and the key exchange (based on the public-private key pair from the certificate). SSL 2.0 was first released in February 1995 (SSL 1.0 was never publicly released because of security flaws). The SSL version involves using a port to make what is known as an explicit connection. If you’re running a commercial business online, this is the certificate you need to use. The TLS protocol used for your website is dependent on the server you’re hosted on.

Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network.Several versions of the protocols are widely used in applications such as web browsing, email, instant messaging, and voice over IP (VoIP). And SSL is the predecessor of TLS. As such, many websites haven’t disabled the features that make a protocol such as TLS 1.2 unsecure.

As you learned above, both public releases of SSL are deprecated in large part because of known security vulnerabilities in them. This protocol uses security mechanisms such as cryptography and hashing to provide security services such as confidentiality, integrity, and endpoint authentication to connections between a server and a client.
