The Linux Foundation sponsored this post. Fortunately the good guys have been able to come up with ways to meet the growing number of hazards.

As mentioned above, one of the ways that TLS 1.3 can encrypt data is to make it so both the client and the server have the capability to encrypt data using the same private key.

The client and server will use their respective secret key values in conjunction with a public key that is known to both to create the ephemeral symmetric key.

Hence, 5 is the value of the shared private key that will be used to encrypt and decrypt data in an exchange between client and server on the internet.
