Aspose.Zip for .NET - Secure File Storage Tutorial

In the world of .NET development, managing and manipulating files is a common task. Aspose.Zip for .NET is a powerful library that provides developers with the capability to compress, decompress, and manipulate zip archives seamlessly. In this tutorial, we will delve into a specific scenario: storing multiple files without compression and protecting them with a password. By the end of this guide, you’ll be equipped with the knowledge to implement this functionality using Aspose.Zip for .NET.

Prerequisites

Before we dive into the tutorial, ensure you have the following prerequisites in place:

• Aspose.Zip for .NET Library: Make sure you have the Aspose.Zip for .NET library installed. You can download it here.

• Document Directory: Prepare a directory where your source files are located. In the provided example, the variable dataDir represents your document directory.

Import Namespaces

To begin, let’s import the necessary namespaces for our code:

// The path to the resource directory.
string dataDir = "Your Document Directory"

// Import Aspose.Zip namespaces
using Aspose.Zip;
using Aspose.Zip.Settings.Compression;
using Aspose.Zip.Settings.Encryption;

Step 1: Open the Zip File

//ExStart: StoreMutlipleFilesWithoutCompressionWithPassword
using (FileStream zipFile = File.Open(dataDir + "StoreMutlipleFilesWithoutCompressionWithPassword_out.zip", FileMode.Create))
{

This step involves creating a new zip file using FileStream. The file will be named “StoreMutlipleFilesWithoutCompressionWithPassword_out.zip.”

Step 2: Open the Source File

using (FileStream source1 = File.Open(dataDir + "alice29.txt", FileMode.Open, FileAccess.Read))
{

Here, we open the first source file, “alice29.txt,” which will be stored in the zip archive.

Step 3: Create an Archive

using (var archive = new Archive(new ArchiveEntrySettings(new StoreCompressionSettings(), new AesEcryptionSettings("p@s$", EncryptionMethod.AES256))))
{

In this step, we create an instance of the Archive class, specifying the compression and encryption settings. We use the StoreCompressionSettings to store files without compression and AesEcryptionSettings to apply AES encryption with a password (“p@s$”).

Step 4: Create Archive Entry and Save

archive.CreateEntry("alice29.txt", source1);
archive.Save(zipFile);

This final step involves creating an entry in the archive for “alice29.txt” and saving the archive, completing the process of storing a file without compression and with password protection.

Conclude your tutorial by summarizing the key points and encouraging readers to explore further possibilities with Aspose.Zip for .NET.

Conclusion

In this tutorial, we explored how to use Aspose.Zip for .NET to store multiple files without compression and secure them with a password. As you continue your journey with .NET development, leverage the capabilities of Aspose.Zip to streamline file management tasks and enhance the security of your applications.
