Certified Ethical Hacker (CEH v10) — Question 120

OpenSSL on Linux servers includes a command line tool for testing TLS. What is the name of the tool and the correct syntax to connect to a web server?

Answer options

• A. openssl s_client ""site www.website.com:443
• B. openssl_client ""site www.website.com:443
• C. openssl_client ""connect www.website.com:443
• D. openssl s_client ""connect www.website.com:443

Correct answer: D

Explanation

The correct answer is D because 'openssl s_client' is the proper command to initiate a TLS connection to a web server. Options A, B, and C are incorrect due to the wrong syntax and command usage; specifically, 'openssl_client' is not a valid command in OpenSSL.
