How many keys are required in asymmetric encryption? - ANSWER 2

Note:
Asymmetric encryption uses a pair of keys called a public/private key
pair.

What is the key length of the Data Encryption Standard (DES)
algorithm? - ANSWER 56-bit

Note:
Let's take a look at some of the key encryption algorithms and their key
lengths.
Data Encryption Standard (DES) - 56-bit
Triple-DES (3DES) - 168-bit
Advanced Encryption Standard (AES) - 256-bit
Twofish - 128, 192, 256-bit

In asymmetric key encryption, what is the next step when a client
initiates a session with a web server that is configured with a certificate?
- ANSWER The web server sends a certificate to the web browser

Note:
How asymmetric encryption works and how asymmetric key is
exchanged between two entities.

1. A client initiates a session with a web server that is configured with a
certificate. For example, the client enters a URL,
https://www.practicelabs.com, in the web browser.
2. The request is received by the web server, which then sends its
certificate to the client. It is important to note that the certificate includes
the public key of the webserver. Remember, it is a pair of public and
