MTD Key Cipher

Nuget Package 1.1.1

The library for exchanging encrypted messages between different applications.

Allows messages to be exchanged kind of class objects.

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);
            
        ....
      }

  ....

  }
