Comparison of the different ACME challenges


I put together a quick table comparing the ACME challenge types.

Hopefully this will be helpful to anyone who would like a quick summary of how the challenges work, maybe advantages/disadvantages, and their differences at a high level. Though implementation may vary widely, this table should still be mostly correct.

Let me know if there’s any corrections to make or rows you’d like to see added!

Edit: Wow, thanks Discourse. Fixed the link above… Here’s the original embed (which doesn’t load on my Chrome):
