The client must complete at least one of a set of challenges for each authorization in order to prove they own the domain. Once complete, the client asks the server to validate each challenge and waits for the server to do so and update the authorization status. .PARAMETER Order The ACME order to perform the validations against. The order object must be associated with the currently active ACME account. .EXAMPLE Submit-ChallengeValidation Begin challenge validation on the current order. .EXAMPLE Get-PAOrder | Submit-ChallengeValidation Begin challenge validation on the current order. .LINK Project: https://github.com/rmbolger/Posh-ACME .LINK Get-PAOrder .LINK New-PAOrder #> } |
