Determines the way in which signing certificates and the certificates from their chain are included in the signed part information.
Values:
none - includes no certificates (default).
signers - includes only the signing certificates, without the certification path.
noroot - includes the entire certification path, except the root certificate.
all - includes all certificates, including the root certificate.
This switch needs only one value. If multiple values are provided, the least restrictive is used, for example
-icsigners;noroot is equivalent to -icnoroot.
