data-defender

To utilise this library add this to your sbt build file

"dev.cjww.libs" % "data-defender_2.13" % "x.x.x" 

Obfuscation and de-obfuscation provide functionality to encrypt type T to a String and decrypt String into type T.

    import dev.cjww.security.obfuscation.Obfuscation
    
    val encString: String = Obfuscation.encrypt(616)

    import dev.cjww.security.deobfuscation.DeObfuscation
    
    val decType: Boolean = DeObfuscation.decrypt[Boolean]("some-padded-string")

Need a encrypt a different type?

Both Obfuscation and DeObfuscation common obfuscators and de-obfuscators that can encrypt and decrypt common types such as String, Int, Boolean and others.

But lets say you want to encrypt something that is covered by the common obfuscators. You have to define your own obfuscator.

    case class ExampleModel(str: String, int: Int)
    
    val testModel = ExampleModel("testString", 616)
    
    implicit val exampleModelObfuscator: Obfuscator[ExampleModel] = new Obfuscator[ExampleModel] {
      override def encrypt(value: ExampleModel): String = Obfuscation.obfuscateJson(Json.toJson(value))
    }
    
    Obfuscation.encrypt(testModel)

Similar if you want to decrypt your example model.

    case class ExampleModel(str: String, int: Int)
    
    val testEncString = "example-padded-string"
    
    implicit val exampleModelDeObfuscator: DeObfuscator[ExampleModel] = new DeObfuscator[ExampleModel] {
      override def decrypt(value: String): Either[ExampleModel, DecryptionError] = DeObfuscation.deObfuscate[ExampleModel](value)
    }
    
    DeObfuscation.decrypt[ExampleModel](testEncString)
