Simply put, it’s up to you. Most browsers will allow the use of any SSL or TLS protocol. However, credit unions and banks should use TLS 1.1 or 1.2 to ensure a protected connection. The later versions of TLS will protect encrypted codes against attacks, and keep your confidential information safe.

How does a TLS connection work?

TLS uses a combination of symmetric and asymmetric cryptography, as this provides a good compromise between performance and security when transmitting data securely. … The session key is then used for encrypting the data transmitted by one party, and for decrypting the data received at the other end.

What is TLS connection?

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. … The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted.

What is the difference between a TLS connection and a TLS session?

It may be shared by multiple SSL connections. Difference between connection and session is that connection is a live communication channel, and session is a set of negotiated cryptography parameters.
