                                function Stop-DbaDbEncryption {

    <#

    .SYNOPSIS

        Decrypts all databases on an instance

    .DESCRIPTION

        Decrypts all databases on an instance

        Removes the encryption key but does not touch certificates or master keys

    .PARAMETER SqlInstance

        The target SQL Server instance or instances.

    .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 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.
