I realize this requirement doesn't perfectly match the lint name, but it is part of 7.1.2.3.b. Is the intention to follow this up with another PR that finishes 7.1.2.3.b?

There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others. Learn more. Can you also add a test case for a legacy certificate with one http CRL distribution point and one non-HTTP distribution point? It wouldn't hurt to add a failing case on non-legacy with the same setup although it's not strictly required it would show that your lint is effectively covering it's multipurpose(s) There was a problem hiding this comment.

I commented "Done" on your other comment twice when I meant to comment it on both comments (including this one). I'm still kinda new to GitHub. |
