SSL Complete Guide 2021: HTTP to HTTPS - How TLS Session is Established

The video tutorial explains why symmetric encryption is used in HTTPS for data transfer, detailing the process of establishing a TLS session. It covers key pursuit negotiation, certificate verification, and symmetric key generation methods, including the Diffie Hellman key exchange. The session concludes with a preview of the next lecture, which will analyze TLS session setup using Wireshark.

Why is symmetric encryption preferred over asymmetric encryption for data transfer in HTTPS?

• Symmetric encryption allows for multiple keys to be used simultaneously.

• Asymmetric encryption is not secure enough for data transfer.

• Asymmetric encryption cannot be used over the internet.

• Symmetric encryption is faster and requires less computational power.

What is the purpose of negotiating a cipher suite during a TLS session?

• To verify the identity of the web browser.

• To determine the web server's IP address.

• To select the protocols for encryption, decryption, and hashing.

• To establish a direct connection between the client and server.

What does a cipher suite specify in a TLS session?

• The physical location of the web server.

• The algorithms for encryption, decryption, and hashing.

• The speed of the internet connection.

• The type of web server being used.

How does a web browser verify a certificate received from a web server?

• By sending a request to the certificate authority.

• By checking the server's IP address.

• By verifying the signature and validity of the certificate.

• By comparing it with a local database of certificates.

What is one method of generating a symmetric key for data encryption?

• Encrypting the key with a password.

• Using the web server's private key.

• Utilizing the Diffie-Hellman key exchange algorithm.

• Generating the key on the server side only.
