/**
* Utility class for `fetch` functions used in `@nestia/sdk` with encryption.
*
* `EncryptedFetcher` is a utility class designed for SDK functions generated by
* [`@nestia/sdk`](https://nestia.io/docs/sdk/sdk), interacting with the remote
* HTTP API encrypted by AES-PKCS algorithm. In other words, this is a
* collection of dedicated `fetch()` functions for `@nestia/sdk` with
* encryption.
*
* For reference, `EncryptedFetcher` class being used only when target
* controller method is encrypting body data by `@EncryptedRoute` or
* `@EncryptedBody` decorators. If those decorators are not used,
* {@link PlainFetcher} class would be used instead.
