    Public Properties
     NameDescription
    Public PropertyCertificateGets or sets a certificate used to generate a digital signature.

    NOTE: This property is obsolete and should not be used. Instead, use SignatureBuilder and Pkcs7SignatureBuilder class to create a PKCS#7 signature and setup its properties.

     
    Public PropertyContactInfoGets or sets the information provided by the signer to enable a recipient to contact the signer to verify the signature (for example, a phone number).  
    Public PropertyDocumentAccessPermissionsGets or sets a document's access permissions granted by this signature. This property can be specified only for one and first signature in the document, this signature will be "certification signature".  
    Public PropertyLocationGets or sets the CPU host name or physical location of the signing.

    By default this property is initialized with System.Environment.MachineName.

     
    Public PropertyReasonGets or sets the reason for the signing, such as "I agree...".  
    Public PropertySignatureAppearanceGets or sets a SignatureAppearance object defining the visual appearance of the generated signature.

    By default this property is initialized with a default instance of the SignatureAppearance class.

     
    Public PropertySignatureBuilderGets or sets a ISignatureBuilder object used to build the signature.  
    Public PropertySignatureDigestAlgorithmGets or sets the signature digest algorithm.

    NOTE: This property is obsolete and should not be used. Instead, use SignatureBuilder and Pkcs7SignatureBuilder class to create a PKCS#7 signature and setup its properties.

    If SignatureFormat is SignatureFormat.PKCS7SHA1, then this property is ignored and SignatureDigestAlgorithm.SHA1 is used.

     
    Public PropertySignatureFieldGets or sets an AcroForm field used to store a digital signature.

    If GrapeCity.Documents.Pdf.AcroForms.SignatureField.Widget is not a null reference (Nothing in Visual Basic), a visual appearance will be generated based on values of the properties SigningDateTime, Location etc.

     
    Public PropertySignatureFormatGets or sets the format of the signature.

    NOTE: This property is obsolete and should not be used. Instead, use SignatureBuilder and Pkcs7SignatureBuilder class to create a PKCS#7 signature and setup its properties.

     
    Public PropertySignerNameGets or sets the name of the person or authority signing the document.

    NOTE: This value is used only if it is not possible to extract the name from the signature, for example from the certificate of the signer.

    By default this property is initialized with System.Environment.UserName.

     
    Public PropertySigningDateTimeGets or sets the time of signing.

    NOTE: This value is used only if 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.

    By default this property is initialized with the current date and time.

     
    Public PropertyTimeStampGets or sets the object implementing the ITimeStampGenerator interface that is used to generate the time-stamp token included in the digital signature of the document.
