Develop platform-independent document signing applications with GroupDocs.Signature for .NET 24.6 (DLLs-only). The DLLs package helps developers with integration and compatibility issues while providing support for GZip and LZip archives signing.

Extensive Support for GZip and LZip Archives

Developers can easily sign and verify documents within GZip and LZip archives with the help of the latest digital signature API for .NET release. The following C# code sample illustrates how to sign a GZip archive.

/// <summary>
/// Support Succeeded and Failed list as result of processing archives
/// This example demonstrates how to sign an archive document using several SignOptions. You can also sign archives in LZip format
/// </summary>
using (var signature = new Signature("sample.pdf.gz"))
{
    // create sign options
    var options = new TextSignOptions("signed!")
    {
        // set signature position
        Left = 100,
        Top = 100
    };
    // sign archive to new zip file
    SignResult result = signature.Sign("output.pdf.gz", options);
    // analyze signed documents
    foreach (DocumentResultSignature document in result.Succeeded)
    {
        Console.WriteLine($"Document {document.FileName}. Processed: {document.ProcessingTime}, mls");
    }
    if (result.Failed.Count > 0)
    {
        Console.WriteLine("\nList of failed documents:");
        foreach (DocumentResultSignature document in result.Failed)
        {
            Console.WriteLine($"Document {document.FileName}. Processed: {document.ProcessingTime}, mls");
        }
    }
}
