SSL Complete Guide 2021: HTTP to HTTPS - Why RSA is not Used for Data Encryption in HTTPS

The video explains why RSA is not used for data encryption in HTTPS, highlighting its inefficiency and the need for bidirectional key pairs. It introduces the TLS protocol, which uses symmetric keys for encryption, and hints at further discussions on certificates and key generation in the next lecture.

Why is RSA not commonly used for data encryption in HTTPS?

• It is slower compared to symmetric key encryption.

• It requires too much storage space.

• It is not compatible with web browsers.

• It is too fast for secure encryption.

What is a key reason RSA is impractical for bidirectional encryption in HTTPS?

• It is not supported by most web servers.

• It can only encrypt small amounts of data.

• It requires a key pair for both the web browser and server.

• It is too expensive to implement.

What is required for bidirectional encryption using RSA?

• A private key for the web browser only.

• Only a public key for the web server.

• No keys are required.

• RSA key pairs for both the web browser and server.

What is the role of TLS in HTTPS?

• To encrypt data using only public keys.

• To set up a secure connection using symmetric key encryption.

• To provide a backup for RSA encryption.

• To replace RSA with a faster algorithm.

How does TLS enhance security in HTTPS?

• By using only public keys for encryption.

• By using RSA keys exclusively.

• By eliminating the need for encryption.

• By generating and securely transferring symmetric keys.
