nmap command indicate that the server is using several ciphers, all of which include the RC4 algorithm. RC4 is considered insecure and has known vulnerabilities. Therefore, the penetration tester should include the following in the report: A. Old, insecure ciphers are in use: The use of RC4 is considered insecure due to vulnerabilities that have been discovered in the algorithm. This is the most relevant issue based on the provided results. Explanation: B. The results do not show the use of the 3DES algorithm, so this is not relevant to the provided data. C. This statement is not accurate. The issue here is not about key size incompatibility with MD5, but rather the insecurity of using RC4 and MD5 in modern cryptographic practices. D. While upgrading to a more recent version of TLS (e.g., TLS 1.2 or TLS 1.3) is generally recommended, the primary concern highlighted by the results is the use of insecure ciphers rather than the TLS version itself.

A. Old, insecure ciphers are in use. The RC4 cipher suite has been deprecated https://www.keysight.com/fr/en/strikes/analysis/tls/rfc7465_rc4_cipher_deprecation.xml#:~:text=As%20of%20RFC7465%2C%20the%20RC4,suites%2C%20including%20RC4%20cipher%20suites.
