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
