Properties

Name Description
CanAddSignatureLine

Gets a bool value indicating whether you can add a signature line to a document. Read-only.
Parent

Returns the Parent object for the specified object.
SkipCertificateValidationOnExporting

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.

If certificate validation is skipped, the certificate will be treated as valid. This is the default behavior.

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.

Methods

Name Description
AddNonVisibleSignature()

Creates a signature packet when digitally signing a document. The signature will be discarded if you save the workbook without signing it.
AddSignatureLine(IWorksheet, double, double, double, double)

Adds lines to a document where signatures are collected. Only the "Microsoft Office signature line" is supported. Other signature line providers, such as stamp signatures, are not supported.
