Bytehide Storage SDK Sample

This sample demonstrates how to use the Bytehide Storage SDK for performing various tasks such as uploading, downloading, compressing, and encrypting files. The example includes:

• Load embedded resources.
• Compress and decompress files locally.
• Upload and download files with encryption and compression.
• Handle text and JSON files securely.
• Zero-knowledge encryption.

Prerequisites

• Install the Bytehide.Storage NuGet package.
• You will need a project token from the Bytehide panel.
• Create an environment with the following structure:
  • /<bucket_name>/images/ for image uploads.
  • /<bucket_name>/texts/ for text uploads.
  • /<bucket_name>/models/ for model uploads.

Installation

Add the ByteHide.Storage SDK to your .NET project via NuGet:

NuGet\\Install-Package Bytehide.Storage

Integration

Once the package is installed, start integrating it into your project.

Code Overview

1. Initialize the Storage Manager

Initialize the StorageManager with your project token.

var storage = new StorageManager();

🔴 Note: Create your environment variables:

• BYTEHIDE_STORAGE_TOKEN your project token.
• BYTEHIDE_STORAGE_PHRASE_ENCRYPTION your encryption phrase.

Or

var storage = new StorageManager("<project_token>", "<phrase_encryption>");

🔴 Note: Consider using a secure method to store the project token and encryption phrase, such as ByteHide Secrets.

Quantum Algorithm Support

The library supports various quantum algorithms designed to protect data against quantum computing threats. These algorithms adhere to post-quantum cryptographic standards. Below is a list of the supported algorithms, along with brief descriptions of each:

public enum QuantumAlgorithmType
{
    Kyber512,
    Kyber768,
    Kyber1024,
    Sntrup761,
    FrodoKem1344Shake,
    MlKem512,
    MlKem768,
    MlKem1024
}

To set a quantum algorithm, use the following code:

var storage = new StorageManager(QuantumAlgorithmType.Kyber1024);

🔴 Note: The default quantum algorithm is Kyber1024.

Algorithm Descriptions

1. Kyber512, Kyber768, Kyber1024

   Kyber is a lattice-based Key Encapsulation Mechanism (KEM), currently recommended by NIST. Variants 512, 768, and 1024 represent increasing levels of security, with Kyber1024 offering the highest level of protection, ideal for applications requiring maximum resistance to quantum attacks.

2. Sntrup761

   Based on NTRU combined with R-LWE (Ring Learning With Errors), Sntrup761 is a fast and secure KEM scheme resistant to quantum attacks. It is designed to balance performance with security, making it suitable for resource-constrained environments.

3. FrodoKem1344Shake

   Part of the FrodoKEM family, this algorithm is based on the LWE problem without using specific algebraic structures. FrodoKem1344Shake leverages the SHAKE hash function to provide a high level of security, suited for scenarios where security is prioritized over speed.

4. MlKem512, MlKem768, MlKem1024

   The MlKem algorithms focus on secure key encapsulation mechanisms using optimized algebraic structures. Versions 512, 768, and 1024 offer different security levels, with MlKem1024 as the most robust, suitable for critical applications demanding high security.

10. Downloading an Image and Saving to Disk

storage
     .In("<bucket_name>/images")
     .SaveToDisk("photo.jpg", "<path_to_downloaded_image>/photo.jpg");

11. Downloading Text Files

Download a text file and save it to disk.

storage
     .In("<bucket_name>/texts")
     .SaveToDisk("payload.txt", "<path_to_downloaded_text>/payload.txt");

Or

storage
     .SaveToDisk("<bucket_name>/texts/payload.txt", "<path_to_downloaded_text>/payload.txt");

Download the text file as a string.

string text = storage
                 .In("<bucket_name>/texts")
                 .GetText("payload.txt");

Or

string text = storage
                  .GetText("<bucket_name>/texts/payload.txt");

Async

string text = await storage
                  .In("<bucket_name>/texts")
                  .GetTextAsync("payload.txt").Result;

Download the text file as a byte array.

byte[] data = storage
                  .In("<bucket_name>/texts")
                  .GetBytes("payload.txt");

Or

byte[] data = storage
                  .GetBytes("<bucket_name>/texts/payload.txt");

Async

string text = await storage
                  .In("<bucket_name>/texts")
                  .GetBytesAsync("payload.txt").Result;

12. Uploading and Downloading JSON Data

Upload a JSON string as a text file.

const string json = "{\"name\":\"John Doe\",\"age\":30}";
var uploaded = storage
                  .In("<bucket_name>/models")
                  .Compress()
                  .Encrypt()
                  .Set("json.txt", json);

// Define a simple class Foo for demonstration purposes
private class Foo
{
    private string Name { get; }
    private int Age { get; }

    public Foo(string name, int age)
    {
        Name = name;
        Age = age;
    }

    public override string ToString() => $"Name: {Name}, Age: {Age}";
}

Download the JSON and deserialize it to a custom Foo object.

var data = storage
               .In("<bucket_name>/models")
               .Get<Foo>("json.txt"); 

Async

var data = await storage
                     .In("<bucket_name>/models")
                     .GetAsync<Foo>("json.txt").Result;

Output

Name: John Doe, Age: 30

Download the JSON as a string.

string text = storage
                  .In("<bucket_name>/models")
                  .GetText("json.txt");

Async

string text = await storage
                        .In("<bucket_name>/models")
                        .GetTextAsync("json.txt").Result;

Output

{"name":"John Doe","age":30}

Notes

The compression and encryption methods can be chained in any order. The order of the methods does not matter.

storage
     .In("<bucket_name>/images")
     .Encrypt()
     .Compress()
     .FromAssembly("photo.jpg", Assembly.GetExecutingAssembly(), "<my_project_>.Resources.<image_path>");

storage
     .In("<bucket_name>/images")
     .Compress()
     .Encrypt()
     .FromAssembly("photo.jpg", Assembly.GetExecutingAssembly(), "<my_project_>.Resources.<image_path>");

If encryption and quantum encryption are used together, it will be applied the last one.

Encryption:

storage
     .In("<bucket_name>/images")
     .EncryptWithQuantum()
     .Encrypt()
     .FromAssembly("photo.jpg", Assembly.GetExecutingAssembly(), "<my_project_>.Resources.<image_path>");

Quantum Encryption:

storage
     .In("<bucket_name>/images")
     .Encrypt()
     .EncryptWithQuantum()
     .FromAssembly("photo.jpg", Assembly.GetExecutingAssembly(), "<my_project_>.Resources.<image_path>");

• The compressed files are detected automatically and decompressed during download.
• The encrypted files are detected automatically and decrypted during download.
