MTD Key Cipher

<a href="https://www.nuget.org/packages/MtdKey.Cipher">Nuget Package 1.0.2</a>

The library for exchanging encrypted messages between different applications.

<p>Allows messages to be exchanged kind of class objects.</p> Creates complex tokens that can be send over HTTP as hyperlinks and make APIs more flexible and secure.

  var tokenModel = new TestTokenModel()
  {
      UserName = "John Doe",
      Password = "password",
      Items = new() { "first", "second" }
  };

  var secretKey = AesCore.GenerateSecretKey();

  //It's an extension of the System.Security.Cryptography.Aes class
  using Aes aes = Aes.Create();
  var tokenEncrypted = aes.EncryptModel(tokenModel, secretKey);

  var tokenDecrypted = aes.DecryptModel<TestTokenModel>(tokenEncrypted, secretKey);

The special AesManager class can be used as a dependent injection in the Asp.Net Web App.

appsettings.json

  "AesOptions": {
    "SecretKey": "[Your secret key]",
    "KeySize": "256"
  },

Program.cs

  builder.Services.AddAesMangerService(options => {
        options.SecretKey = builder.Configuration.GetValue<string>("AesOptions:SecretKey");
        options.KeySize = builder.Configuration.GetValue<int>("AesOptions:KeySize");
  });

Index.cshtml.cs

  public class IndexModel : PageModel
  {
      private readonly IAesManager aesManager;

      public IndexModel(IAesManager aesManager)
      {
          this.aesManager = aesManager;
      }

      public IActionResult OnPost()
      {

        var encryptedData = aesManager.EncryptModel(tokenModel);
        var decryptedModel = aesManager.DecryptModel(encryptedData);
