Hi @nabla-c0d3, do you have bandwidth to work on this or do you need help with it? This would unblock some dependency updates for us.

Fixed as part of v5.1.2.

@eloquence Hello! Which of your projects is using sslyze? Just curious

[eloquence]

Thanks much @nabla-c0d3! We have a custom test suite that performs various config checks against our prod websites (in a private repo right now), and we also use pshtt (forked because it has its own set of dependency issues) as part of our landing page scanner for SecureDrop landing pages.
