SSL Complete Guide 2021: HTTP to HTTPS - Exploring TLS Certificates Via Shell

The video tutorial guides viewers through examining and analyzing SSL/TLS certificates on a server. It covers accessing the server via SSH, exploring certificate files, and using online tools to decode and analyze certificate details. The tutorial emphasizes understanding certificate chains, intermediate certificates, and the importance of sending the full chain to web browsers for verification. It also highlights the security settings of TLS protocols and the role of private keys.

What is the first step in examining the certificate files on the server?

• Using a web browser to view the certificate

• Downloading the certificate to a local machine

• Opening the certificate in a text editor

• Changing directory to the certificate location

Which command is used to connect to the server via SSH?

• ssh root@

• ftp root@

• scp root@

• telnet root@

What information can be obtained from a certificate decoder tool?

• Network bandwidth

• Operating system version

• Server's IP address

• Common name and issuer

What is the overall security rating of the certificate and TLS settings?

• C

• B

• A

• D

Which TLS version is enabled but marked for deprecation?

• TLS 1.2

• TLS 1.1

• TLS 1.3

• TLS 1.0

What hashing algorithm is used in the encryption protocol?

• RSA

• MD5

• AES

• SHA

Why is it important to send the entire certificate chain to web browsers?

• To ensure the browser can verify the entire chain

• To reduce server load

• To encrypt the data

• To increase download speed

What is the purpose of the 'fullchain.pem' file?

• It logs server access attempts

• It lists all server users

• It stores the server's private key

• It contains the entire certificate chain

What is the role of intermediate certificates in the certificate chain?

• They manage server load

• They bridge the gap between the root certificate and the server certificate

• They encrypt the server's data

• They store user credentials

What is the validity period of the intermediate certificate?

• Five years

• One year

• Ten years

• Three months
