    Public Properties
     NameDescription

    Public PropertyFilterGets the name of the preferred signature handler to use when validating this signature.  
    Public PropertyLocationGets the CPU host name or physical location of the signing.  
    Public PropertyNameGets the name of the person or authority signing the document. This value should be used only when it is not possible to extract the name from the signature; for example, from the certificate of the signer.  
    Public PropertyObjIDGets the PDF object ID. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfWrapperBase)
    Public PropertyPdfDictGets the underlying GrapeCity.Documents.Pdf.Spec.IPdfDict. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfDictWrapper)
    Public PropertyPdfObjectGets the underlying GrapeCity.Documents.Pdf.Spec.IPdfObject. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfWrapper<IPdfDict>)
    Public PropertyReasonGets the reason for the signing, such as "I agree...".  
    Public PropertySigningTimeGets the time of signing. Depending on the signature handler, this may be a normal unverified computer time or a time generated in a verifiable way from a secure time server. This value should be used only when the time of signing is not available in the signature; for example, a time stamp can be embedded in a PKCS#7 binary data object (see PDF specification for more details).  
    Public PropertySubFilterGets a name that describes the encoding of the signature value and key information in the signature dictionary.  
    Public PropertyTypeGets the signature type, if present, shall be "Sig" for a signature dictionary or "DocTimeStamp" for a time-stamp signature dictionary.
