FirebaseAESLib 1.0.0

📘 README – How to Use FirebaseAESLib 🔧 Step 1: Install NuGet Packages in Your App In your app project (Console, MAUI, etc):

dotnet add package DotNetEnv dotnet add package Google.Cloud.Firestore dotnet add package FirebaseDatabase.net

📁 Step 2: Create .env File in App Project Root env

Firestore

FIREBASE_PROJECT_ID=your-project-id GOOGLE_APPLICATION_CREDENTIALS=./serviceAccountKey.json

Realtime DB

FIREBASE_DATABASE_URL=https://your-db.firebaseio.com/ FIREBASE_DATABASE_SECRET=your-legacy-db-secret

AES

AES_KEY=base64-aes-key AES_IV=base64-aes-iv Generate a 256-bit AES key & IV (in base64):

using System.Security.Cryptography;

var aes = Aes.Create(); Console.WriteLine(Convert.ToBase64String(aes.Key)); // AES_KEY Console.WriteLine(Convert.ToBase64String(aes.IV)); // AES_IV 🧪 Step 3: Example Usage in Your App

using DotNetEnv; using FirebaseAESLib;

Env.Load(); // Load .env variables

var aes = new AesEncryptor( Environment.GetEnvironmentVariable("AES_KEY"), Environment.GetEnvironmentVariable("AES_IV") );

// Firestore setup var firestore = new FirestoreService( Environment.GetEnvironmentVariable("FIREBASE_PROJECT_ID"), Environment.GetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS"), aes );

// Realtime DB setup var realtime = new RealtimeDatabaseService( Environment.GetEnvironmentVariable("FIREBASE_DATABASE_URL"), Environment.GetEnvironmentVariable("FIREBASE_DATABASE_SECRET"), aes );

// Sample encrypted user object var user = new Dictionary<string, object> { { "name", "Kevin" }, { "email", "kevin@example.com" }, { "verified", true } };

// Store encrypted await firestore.SetEncryptedAsync("users", "user1", user); await realtime.SetEncryptedAsync("users/user1", user);

// Retrieve decrypted var firestoreDecrypted = await firestore.GetDecryptedAsync("users", "user1"); var realtimeDecrypted = await realtime.GetDecryptedAsync("users/user1");

Console.WriteLine("Firestore: " + Newtonsoft.Json.JsonConvert.SerializeObject(firestoreDecrypted)); Console.WriteLine("Realtime: " + Newtonsoft.Json.JsonConvert.SerializeObject(realtimeDecrypted));
