                                function Remove-DbaDbCertificate {

    <#

    .SYNOPSIS

        Deletes specified database certificate

    .DESCRIPTION

        Deletes specified database certificate

    .PARAMETER SqlInstance

        The SQL Server to create the certificates on.

    .PARAMETER SqlCredential

        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .PARAMETER Database

        The database where the certificate will be removed.

    .PARAMETER Certificate

        The certificate that will be removed

    .PARAMETER WhatIf

        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm

        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException

        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER InputObject

        Piped certificate objects
