A signature confirms that the digital document originated from the signer and has not been tampered with during transit. The use of digital signatures eliminates the need for sending paper documents, and reduces the number of the documents that need to be printed, mailed, and stored, saving you time and money. In this article, you will learn how to digitally sign a Word document in C# and VB.NET using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Add a Digital Signature to Word in C#, VB.NET
The steps are as follows.
- Create a Document object.
- Load a Word document using Document.LoadFromFile() method.
- Specify the path and the password of a .pfx certificate.
- Digitally sign the document while saving the document using Document.SaveToFile(string fileName, FileFormat fileFormat, string certificatePath, string securePassword) method. Here are some other methods that you can use to digitally sign a Word document.
- public void SaveToFile(string fileName, FileFormat fileFormat, byte[] certificateData, string securePassword);
- public void SaveToStream(Stream stream, FileFormat fileFormat, byte[] certificateData, string securePassword);
- public void SaveToStream(Stream stream, FileFormat fileFormat, string certificatePath, string securePassword);
- public static byte[] Document.Sign(Stream sourceStream, byte[] certificateData, string securePassword);
- public static byte[] Document.Sign(Stream sourceStream, string certificatePath, string securePassword);
- C#
- VB.NET
using Spire.Doc;
namespace DigitallySignWord
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document doc = new Document();
//Load a Word file
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");
//Specify the certificate path
string certificatePath = "C:\\Users\\Administrator\\Desktop\\gary.pfx";
//Specify the password of the certificate
string password = "e-iceblue";
//Digitally sign the document while saving it to a .docx file
doc.SaveToFile("AddDigitalSignature.docx", FileFormat.Docx2013, certificatePath, password);
}
}

static void Main(string[] args)
{
//Create a new word document
Document document = new Document();
//Add a section to the document
Section section = document.AddSection();
//Add a document to the section
Paragraph paragraph = section.AddParagraph();
//Add checkbox content control
StructureDocumentTagInline sdt = new StructureDocumentTagInline(document);
paragraph = section.AddParagraph();
sdt = new StructureDocumentTagInline(document);
sdt.CharacterFormat.FontSize = 20;
paragraph.ChildObjects.Add(sdt);
sdt.SDTProperties.SDTType = SdtType.CheckBox;
SdtCheckBox scb = new SdtCheckBox();
sdt.SDTProperties.ControlProperties = scb;
TextRange tr = new TextRange(document);
tr.CharacterFormat.FontName = "MS Gothic";
tr.CharacterFormat.FontSize = 20;
sdt.ChildObjects.Add(tr);
scb.Checked = true;
sdt.SDTProperties.Alias = "CheckoBox";
sdt.SDTProperties.Tag = "Checkbox";
//Add picture content control
paragraph = section.AddParagraph();
sdt = new StructureDocumentTagInline(document);
paragraph.ChildObjects.Add(sdt);
sdt.SDTProperties.ControlProperties = new SdtPicture();
sdt.SDTProperties.Alias = "Picture";
sdt.SDTProperties.Tag = "Picture";
DocPicture pic = new DocPicture(document) { Width = 10, Height = 10 };
pic.LoadImage(Image.FromFile("Logo.jpg"));
sdt.SDTContent.ChildObjects.Add(pic);
document.SaveToFile("Sample.docx", FileFormat.Docx2013);
}
}
}

Headers are text or pictures on the top of pages in Word documents while footers are at the bottom. People usually use headers and footers to display some important information about documents, such as copyright, author information, and page numbers or just to make the document more good-looking and professional. They can be inserted into a Word document on every page, only on the first page, or differently on odd pages and even pages. This article will show how to insert headers and footers into Word documents programmatically using Spire.Doc for Java.

Insert Headers and Footers into a Word Document
To insert a header or a footer into a Word document using Spire.Doc for Java, you need to use Section.getHeadersFooters().getHeader() and Section.getHeadersFooters().getFooter() methods to get them and then add paragraphs to them to insert pictures, text, or page number fields.
The detailed steps for inserting headers and footers are as follows:
- Create an instance of Document class.
- Load a Word document using Document.loadFromFIle() method.
- Get the first section using Document.getSections().get() method.
- Call the custom method insertHeaderAndFooter() to insert a header and a footer into the section.
- Save the document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.TextRange;
public class insertHeaderAndFooter {
public static void main(String[] args) {
//Create a Document class instance
Document document = new Document();
//Load a Word document
document.loadFromFile("We Are Interwoven Beings.docx");
//Get the first section
Section section = document.getSections().get(0);
//Call the custom method insertHeaderAndFooter() to insert headers and footers to the section
insertHeaderAndFooter(section);
//Save the document
document.saveToFile("HeaderAndFooter.docx", FileFormat.Docx);
}
private static void insertHeaderAndFooter(Section section) {
//Get header and footer from a section
HeaderFooter header = section.getHeadersFooters().getHeader();
HeaderFooter footer = section.getHeadersFooters().getFooter();
//Add a paragraph to the header
Paragraph headerParagraph = header.addParagraph();
//Add text to the header paragraph
TextRange text = headerParagraph.appendText("Philosophy\rWe Are Interwoven Beings");
text.getCharacterFormat().setFontName("Arial");
text.getCharacterFormat().setFontSize(12);
text.getCharacterFormat().setItalic(true);
headerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
//Set the bottom border style of the header paragraph
headerParagraph.getFormat().getBorders().getBottom().setBorderType(BorderStyle.Single);
headerParagraph.getFormat().getBorders().getBottom().setLineWidth(1f);
//Add a paragraph to the footer
Paragraph footerParagraph = footer.addParagraph();
//Add Field_Page and Field_Num_Pages fields to the footer paragraph
footerParagraph.appendField("Page Number", FieldType.Field_Page);
footerParagraph.appendText(" of ");
footerParagraph.appendField("Number of Pages", FieldType.Field_Num_Pages);
footerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
//Set the top border style of the footer paragraph
footerParagraph.getFormat().getBorders().getTop().setBorderType(BorderStyle.Single);
footerParagraph.getFormat().getBorders().getTop().setLineWidth(1f);
}
}
Insert a Header and a Footer Only into the First Page of a Word Document
Sometimes we only need to insert a header and a footer into the first page, which can be realized by Spire.Doc for Java as well. We can use Section.getPageSetup().setDifferentFirstPageHeaderFooter() method to make the headers and footers of the first page different from other pages.
The detailed steps for inserting header and footer only into the first page are as follows:
- Create a Document class instance.
- Load a Word document using Document.loadFromFile() method.
- Get the first section using Document.getSections().get() method.
- Make the headers and footers of the first page different from other pages using Section.getPageSetup().setDifferentFirstPageHeaderFooter() method.
- Call the custom method insertHeaderAndFooterFirst() to insert a header and a footer into the first page.
- Save the document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.DocPicture;
import com.spire.doc.fields.TextRange;
import java.awt.*;
public class insertHeaderAndFooter {
public static void main(String[] args) {
//Create a Document class instance
Document document = new Document();
//Load a Word document
document.loadFromFile("We Are Interwoven Beings.docx");
//Get the first section
Section section = document.getSections().get(0);
//Make the headers and footers of the first page different from other pages
section.getPageSetup().setDifferentFirstPageHeaderFooter(true);
//Call the custom method insertHeaderAndFooterFirst() to insert a header and a footer into the first page
insertHeaderAndFooterFirst(section);
//Save the document
document.saveToFile("FirstPageHeaderAndFooter.docx", FileFormat.Docx);
}
private static void insertHeaderAndFooterFirst(Section section) {
//Get header and footer of the first page
HeaderFooter header = section.getHeadersFooters().getFirstPageHeader();
HeaderFooter footer = section.getHeadersFooters().getFirstPageFooter();
//Add a paragraph to the header
Paragraph headerParagraph = header.addParagraph();
//Add text to the header paragraph
TextRange text = headerParagraph.appendText("Philosophy");
text.getCharacterFormat().setFontName("Arial");
text.getCharacterFormat().setFontSize(14);
text.getCharacterFormat().setTextColor(Color.blue);
text.getCharacterFormat().setItalic(true);
headerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);
//Insert a picture into the header paragraph and set its position
DocPicture headerPicture = headerParagraph.appendPicture("Header.png");
headerPicture.setHorizontalAlignment(ShapeHorizontalAlignment.Left);
headerPicture.setVerticalOrigin(VerticalOrigin.Top_Margin_Area);
headerPicture.setVerticalAlignment(ShapeVerticalAlignment.Center);
//Set text wrapping style to Behind
headerPicture.setTextWrappingStyle(TextWrappingStyle.Behind);
//Set the bottom border style of the header paragraph
headerParagraph.getFormat().getBorders().getBottom().setBorderType(BorderStyle.Single);
headerParagraph.getFormat().getBorders().getBottom().setLineWidth(1f);
//Add a paragraph to the footer
Paragraph footerParagraph = footer.addParagraph();
//Add text to the footer paragraph
TextRange text1 = footerParagraph.appendText("We Are Interwoven Beings");
text1.getCharacterFormat().setFontName("Arial");
text1.getCharacterFormat().setFontSize(14);
text1.getCharacterFormat().setTextColor(Color.BLUE);
text1.getCharacterFormat().setItalic(true);
footerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
//Set the top border style of the footer paragraph
footerParagraph.getFormat().getBorders().getTop().setBorderType(BorderStyle.Single);
footerParagraph.getFormat().getBorders().getTop().setLineWidth(1f);
}
}
Insert Different Headers and Footers into Odd Pages and Even Pages
We may also encounter situations where we need to insert different headers and footers into odd pages and even pages. Spire.Doc for Java provides a method Section.getPageSetup().setDifferentOddAndEvenPagesHeaderFooter(), which can make headers and footers different on odd pages and even pages, to meet such needs.
The detailed steps for inserting different headers and footers into odd pages and even pages are as follows:
- Create an object of Document class.
- Load a Word document using Document.loadFromFile() method.
- Get the first section using Document.getSections().get() method.
- Make the headers and footers of odd pages and even pages different using Section.getPageSetup().setDifferentOddAndEvenPagesHeaderFooter() method.
- Call the custom method insertHeaderAndFooterOddEven() to insert different headers and footers into odd pages and even pages.
- Save the document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.TextRange;
import java.awt.*;
public class insertHeaderAndFooter {
public static void main(String[] args) {
//Create a Document class instance
Document document = new Document();
//Load a Word document
document.loadFromFile("We Are Interwoven Beings.docx");
//Get the first section
Section section = document.getSections().get(0);
//Make the headers and footers of odd pages and even pages different
section.getPageSetup().setDifferentOddAndEvenPagesHeaderFooter(true);
//Call the custom method insertHeaderAndFooterOddEven() to insert different headers and footers into odd pages and even pages
insertHeaderAndFooterOddEven(section);
//Save the document
document.saveToFile("OddEvenHeaderAndFooter.docx", FileFormat.Docx);
}
private static void insertHeaderAndFooterOddEven(Section section) {
//Insert odd header
Paragraph P1 = section.getHeadersFooters().getOddHeader().addParagraph();
TextRange OH = P1.appendText("Odd Header");
P1.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
OH.getCharacterFormat().setFontName("Arial");
OH.getCharacterFormat().setFontSize(16);
OH.getCharacterFormat().setTextColor(Color.RED);
//Insert even header
Paragraph P2 = section.getHeadersFooters().getEvenHeader().addParagraph();
TextRange EH = P2.appendText("Even Header");
P2.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
EH.getCharacterFormat().setFontName("Arial");
EH.getCharacterFormat().setFontSize(16);
EH.getCharacterFormat().setTextColor(Color.RED);
//Insert odd footer
Paragraph P3 = section.getHeadersFooters().getOddFooter().addParagraph();
TextRange OF = P3.appendText("Odd Footer");
P3.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
OF.getCharacterFormat().setFontName("Arial");
OF.getCharacterFormat().setFontSize(16);
OF.getCharacterFormat().setTextColor(Color.RED);
//Insert even footer
Paragraph P4 = section.getHeadersFooters().getEvenFooter().addParagraph();
TextRange EF = P4.appendText("Even Footer");
EF.getCharacterFormat().setFontName("Arial");
EF.getCharacterFormat().setFontSize(16);
P4.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
EF.getCharacterFormat().setTextColor(Color.RED);
}
