What is TLS encryption?

TLS encryption works by establishing a secure connection between two parties, like your web browser and a website, using a combination of encryption and authentication methods. Here’s how it typically unfolds:

• The process starts with a TLS handshake, during which the client (your browser) and the server (the website) agree on encryption protocols and exchange keys.

• The server provides a digital certificate to prove its identity, which the client verifies using a trusted certificate authority.

• Once trust is confirmed, both parties create a shared session key, which encrypts all data exchanged during the session.

TLS secures communications using two types of encryption:

• Asymmetric encryption during the handshake to establish trust.

• Symmetric encryption for the actual data transfer, making the process faster and efficient.

You might recognize TLS in action whenever you see “HTTPS” and the lock icon in your browser’s address bar.
