This on-premise .NET API lets your app end-users sign the electronic documents from a wide range of file formats. Supports several types of e-signing methods.

Document Signature Processing Features

  • Create and add signatures to documents of various file formats.
  • Specify visual attributes of signatures, such as color, font, margins, etc.
  • Search and fetch a list of signatures from a document.
  • Determine if the document contains signatures meeting specified criteria.
  • Extract basic information about the document.
  • Generate image representation of document pages for preview.
  • Distinguish created signatures from the actual document.
  • Put encrypted text into the QR-code signature or embed custom data objects.

What's new in v22.10.0

Get Metadata Signature using DocumentInfo

This API release has implemented a new MetadataSignatures property for DocumentInfo class to include standard document metadata signatures.

The following C# code sample fetches all document signature of metadata type using API:

public static void Run()
{
    // specify custom settings to include standard document metadata signatures (Author, Owner, Creation date, etc)
    var settings = new SignatureSettings()
    {
        IncludeStandardMetadataSignatures = true
    };
    // create the Signature instance with the settings
    using (Signature signature = new Signature("signedContract.docx", settings))
    {
        IDocumentInfo documentInfo = signature.GetDocumentInfo();
        Console.WriteLine($"Document properties {Path.GetFileName(filePath)}:");
        Console.WriteLine($" - format : {documentInfo.FileType.FileFormat}");
        Console.WriteLine($" - extension : {documentInfo.FileType.Extension}");
        Console.WriteLine($" - size : {documentInfo.Size}");
        Console.WriteLine($" - page count : {documentInfo.PageCount}");
        foreach (PageInfo pageInfo in documentInfo.Pages)
        {
            Console.WriteLine($" - page-{pageInfo.PageNumber} Width {pageInfo.Width}, Height {pageInfo.Height}");
        }
        
        // display document Metadata signatures information
        Console.WriteLine($"Document Metadata signatures : {documentInfo.MetadataSignatures.Count}");
        foreach (MetadataSignature metadataSignature in documentInfo.MetadataSignatures)
        {
            Console.WriteLine($" - #{metadataSignature.Name} = {metadataSignature.Value}");
        }
    }
}

        EncodeType = QRCodeTypes.QR,
        Left = 100,
        Top = 100
    };
    PdfSaveOptions pdfSaveOptions = new PdfSaveOptions()
    {
        FileFormat = PdfSaveFileFormat.DocX,
        OverwriteExistingFiles = true
    };
    // sign document to file
    signature.Sign("SignedPdf.docx", signOptions, pdfSaveOptions);
}

Use C# to Search and Delete Signatures from a DOCX File

// initialize Signature instance
using (Signature signature = new Signature("signed.docx"))
{
    BarcodeSearchOptions options = new BarcodeSearchOptions();
    List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);
    List<BaseSignature> signaturesToDelete = new List<BaseSignature>();
    // collect signatures to delete
    foreach (BarcodeSignature temp in signatures)
    {
        if (temp.Text.Contains("John"))
        {
            signaturesToDelete.Add(temp);
        }
    }
    // delete signatures
    DeleteResult deleteResult = signature.Delete(signaturesToDelete);
    if (deleteResult.Succeeded.Count == signaturesToDelete.Count)
    {
        Console.WriteLine("All signatures were successfully deleted!");
    }
    else
    {
        Console.WriteLine($"Successfully deleted signatures : {deleteResult.Succeeded.Count}");
        Console.WriteLine($"Not deleted signatures : {deleteResult.Failed.Count}");
    }
    Console.WriteLine("List of deleted signatures:");
    foreach (BaseSignature temp in deleteResult.Succeeded)
    {
        Console.WriteLine($"Signature# Id:{temp.SignatureId}, Location: {temp.Left}x{temp.Top}. Size: {temp.Width}x{temp.Height}");
    }
}
