Question: What Is A TLS Email Connection?

What does TLS mean in email?

Transport Layer SecurityRequire mail to be transmitted via a secure (TLS) connection.

Transport Layer Security (TLS) is a security protocol that encrypts email to protect its privacy.

Is Gmail SSL or TLS?

TLS is the successor to Secure Sockets Layer (SSL). Gmail always uses TLS by default. To create a secure connection, both the sender and recipient must use TLS. When a secure connection can’t be created, Gmail delivers messages over non-secure connections.

Where is TLS used?

A primary use case of TLS is encrypting the communication between web applications and servers, such as web browsers loading a website. TLS can also be used to encrypt other communications such as email, messaging, and voice over IP (VOIP).

How does a TLS connection work?

A TLS handshake is the process that kicks off a communication session that uses TLS encryption. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the encryption algorithms they will use, and agree on session keys.
