Storage (Object storage powered by Post-Quantum Cryptography)

How do I upload and manage files in Storage?

To upload files, you can use the Storage SDK for .NET, which provides an intuitive API. You can upload files as public, private, or temporary, and configure encryption and compression. Managing files includes listing, searching, organizing into directories, and setting expiration rules for temporary files.

Example of uploading a public file:

var storage = new StorageManager();
byte[] data = Encoding.UTF8.GetBytes("File content");

StorageResult result = await storage
    .AsPublic()
    .Set("filename.txt", data);

Console.WriteLine($"Uploaded to: {result.Path}");
Console.WriteLine($"Public URL: {result.PublicUrl}");

Is Storage encrypted end-to-end?

Yes. Storage implements end-to-end encryption, meaning files are encrypted before leaving your application and remain encrypted until you retrieve and decrypt them. ByteHide does not have access to your encryption keys (Zero-knowledge model), ensuring complete data privacy.

How do I set permissions for different users in Storage?

Storage allows you to define file permissions easily:

Public: Accessible by anyone with the link.
Private: Only your application can access the file.
Temporary: Files that automatically expire after a defined period.

Example of a temporary file that expires in 1 hour:

var storage = new StorageManager();
byte[] data = Encoding.UTF8.GetBytes("Confidential content");

StorageResult result = await storage
    .AsTemporal(3600) // Expires in 3600 seconds (1 hour)
    .Set("secure-file.txt", data);

Console.WriteLine($"File will expire at: {result.Expiration}");

What’s the maximum file size supported by Storage?

The maximum files size is 5GB unless you have the enterprise edition.

How does Storage ensure data integrity and redundancy?

Storage uses encryption before transmission and ensures secure data storage in the cloud. It is designed to protect data from unauthorized access and corruption, following security best practices.

Can I integrate Storage with my existing applications?

Yes. Storage is designed for easy integration with .NET applications, including .NET MAUI, Xamarin, Blazor, ASP.NET, and other frameworks. It provides a simple SDK that allows you to store and retrieve files securely with minimal configuration.

How do I retrieve and download files securely?

You can download files using the Storage SDK, ensuring that encrypted files remain secure during transmission.

Example of retrieving a file as text:

var storage = new StorageManager();
string content = await storage.GetText("public/images/photo.png");

Console.WriteLine($"File content: {content}");

If a file is encrypted, only your application can decrypt it since ByteHide does not store your encryption keys.

What happens if I delete a file? Can I recover it?

Once a file is deleted, it cannot be recovered.
