<div class="markdown level1 summary"><p>Indicates whether the validation of the attached digital certificate of the signed signature
should be skipped when exporting signed signatures. The default value is true.</p>
<p>
If certificate validation is skipped, the certificate will be treated as valid.
This is the default behavior.
</p><p>
Otherwise, the certificate will be validated with X.509 chain. 
The validation requires Internet connection and
will read the X.509 certificate storage of the current user and local machine.
