/**
 * Encrypted body decorator.
 *
 * `EncryptedBody` is a decorator function getting `application/json` typed data
 * from request body which has been encrypted by AES-128/256 algorithm. Also,
 * `EncryptedBody` validates the request body data type through
 * [typia](https://github.com/samchon/typia) ad the validation speed is maximum
 * 15,000x times faster than `class-validator`.
 *
 * For reference, when the request body data is not following the promised type
 * `T`, `BadRequestException` error (status code: 400) would be thrown. Also,
 * `EncryptedRoute` decrypts request body using those options.
 *
 * - AES-128/256
 * - CBC mode
 * - PKCS #5 Padding
 * - Base64 Encoding
