                                function Backup-DbaComputerCertificate {

    <#

    .SYNOPSIS

        Backs up a computer certificate - useful for older systems and backing up remote certs to local disk.

    .DESCRIPTION

        Backs up a computer certificate - useful for older systems and backing up remote certs to local disk.

    .PARAMETER InputObject

        The target certificate object. Accepts input from Get-DbaComputerCertificate.

    .PARAMETER Path

        Export to a directory

    .PARAMETER FilePath

        Export to a specific file name

    .PARAMETER Type

        Export type. Options include: Authenticode, Cert, Pfx, Pkcs12, Pkcs7, SerializedCert.

    .PARAMETER SecurePassword

        Export using a password

    .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.
