[computer-security-2023-2024] Ammendment to Netsec homework

Hi everyone,

Regarding Question 6 about Certificates in the network security homework, in sub-question 7 you should obtain the OCSP URL from the *leaf* certificate and the CRL distribution URL from the *intermediate* certificate. Then, in sub-question 8 use the CRL downloaded from the intermediate certificate.

Note that even if you see news that Let'sEncrypt no longer uses CRLs, the CRL distribution URL is available in the intermediate certificate and can be downloaded.

Best regards,

Juan
