Question 1: Version of TLS

What is the version of TLS used in this trace ?

TLS 1.2

TLS 1.3

TLS 1.0

Question 2: Cipher suites

How many different cipher suites are proposed by this client ?

Question 3: Server name

The Server Name Indication is a TLS extension that is used by the client to specify the fully qualified domaine name of the contacted server. What is the name of the server contacted in this trace ?

Question 4: Cipher suite

In TLS, the server selects its preferred cipher suite among the ones supported by the client. These cipher suites are encoded as a string. What is the cipher suite used in this trace ?

Question 5: Server certificate

A TLS server sends its certificate to prove its identity. What is the issuer of the certificate used in this trace ?

Question 6: Certificate validity

TLS certificates are valid for some time. On which day will the certificate announced by this server will be invalid ? Provide your answer as year-month-day with 2 digits for year, month and day.

Question 7: A TLS trace

The attached packet trace was collected on a Linux client.
