Obsolete property in Challenge resource

[JeffreyVerbeek]

When using IChallengeContext.Resource() the response is a Challenge object with a status. If the status comes back invalid there should be an error object. The current IList<object> Errors in the code is always null becouse the property has been replaced since draft 10. It is now a single error with subproblems. It can be fould in section-8

At the moment I am not able to get the reason why validation vailed.
Is this something you want to fix yourself or should I create a Pull request?

Hi @JeffreyVerbeek , thanks for the investigation, and PR would be nice. 👍

This was actually an easy fix. But I did find something else.
You are expecting a string KeyAuthorization which I did not find in the spec.
The DateTimeOffset? Validated is not used for some reason. The spec says this property should be used if the validation is valid, but Let's Encrypt does not send it.
Let's Encrypt does send an object validationRecord which is not in the spec. Maybe this is something to look into?!

Thanks @JeffreyVerbeek

• keyAuthorization is in draft-09, I think we can mark it obsoleted now.
• Validated is in draft-12, so let's keep it.
• LE has always sending validationRecord in challenges, if it's useful for you, feel free to create new issue/PR for it.
