How to Decrypt and Use Encrypted Response in Ktor HTTP Client

I'm working on an Android application where I need to encrypt the request body before sending it to the server and then decrypt the response received from the server. I'm using Ktor's HTTP client for network requests and I have a CryptoUtils class that handles encryption and decryption using AES. Here's an outline of what I have done:

1. Encryption: I have successfully installed a plugin to encrypt the request body before it's sent to the server. Here's the code for the encryption install (this exemple is for login only, i willl make it global later):

private fun HttpClientConfig<OkHttpConfig>.encryptionInstall() {    install("EncryptRequest") {        requestPipeline.intercept(HttpRequestPipeline.Transform) { request ->            if (request !is EmptyContent) {                val request = request as LoginDTO                val originalBody = Json.encodeToString(x)                val encryptionKey = "MY_ENCRYPTION_KEY"                val encryptedBody = CryptoUtils.encryptData(                    encryptionKey, originalBody                )                val encryptedContent = TextContent(encryptedBody, ContentType.Application.Json)                proceedWith(encryptedContent)            } else {                proceedWith(request)            }        }    }}

2. encryption: Now, I'm trying to decrypt the response received from the server using the DecryptResponse plugin. Here's the code for the decryption install:

private fun HttpClientConfig<OkHttpConfig>.decryptInstall() {    install("DecryptResponse") {        receivePipeline.intercept(HttpReceivePipeline.After) { response ->            val originalResponseReceived = response.body<String>()            runCatching {                val encryptionKey = "MY_DECRYPTION_KEY"                val decryptData = CryptoUtils.decryptData(                    encryptionKey, originalResponseReceived.toString().replace("\n", "")                )                val castedFromStringToObject =                    Json.decodeFromString<LoginResponseDTO>(decryptData.orEmpty())                // Now I have the decrypted data, how do I proceed with it?                // I need to create an HttpResponse object with this decrypted data.                // But I can't create an instance of an abstract class HttpResponse.                // How can I create a new HttpResponse to proceed with the decrypted data?            }        }    }}

I tried decrypting the response using the DecryptResponse plugin and I successfully decrypted the content. However, I encountered an issue when trying to proceed with the decrypted data. Since HttpResponse is an abstract class, I couldn't directly create an instance of it to proceed with the decrypted data.

I was expecting to be able to create a new HttpResponse object with the decrypted data so that I can continue processing it. However, since HttpResponse is abstract, I'm not sure how to proceed. I need guidance or examples on how to create a new HttpResponse to proceed with the decrypted data after decryption.

Any insights or examples on how to achieve this would be greatly appreciated.

Thank you in advance for your help!
