Unable to Verify HMAC from Submit-ChallengeValidation with the DMEasy plugin

[mrdenny]

We're attempting to register for a certificate where the domain is registered with DNS Made Easy so were using the DMEasy plugin. We've got the API Key and secret setup and being password back.

We're getting the following error message back. Is this message coming form DNS Made Easy? (I didn't see the message as hard coded in the cmdlet, so I'm assuming that it is.)

Submit-ChallengeValidation : {"error": ["Unable to verify HMAC"]} At C:\Program Files\WindowsPowerShell\Modules\Posh-ACME\4.25.1\Public\New-PACertificate.ps1:258 char:9

There was a space before the key value, which is what caused the error.
