はので、私はollydbg使用して、うまく最初私はこの暗号がXTEAしかしXTEAがプレーンテキストでANDをしないことと考えていたことがわかったので、私は、私は多分誰かがそれを識別し、ここでこの暗号を投稿して考えて、私はそれが既存の暗号であるかどうかを教えてください。これはカスタム暗号であり、このasmコードに基づいて記述する必要があります。ありがとう。は暗号暗号を識別

そして、それはC++と関係がありますか？ –

これは暗号化（または復号化）ラウンドに過ぎず、初期化機能を確認するのに役立ちます。しかし、それはブローフィッシュのようなにおいがする。ウィキペディアから：

フグは64ビットブロックサイズ[...]このアルゴリズムは、2つのサブキー アレイ維持有する：18エントリP-アレイと4 256エントリをS-ボックス。 Sボックス は8ビット入力を受け付け、32ビット出力を生成します。 P-アレイ の1つのエントリが毎回使用され、最終ラウンドの後に、データ ブロックの各半分は、残りの2つの未使用Pエントリの1つと排他的論理和が取られる。

そしてここでは、コードがヘックス・レイズデコンパイラを通してそれを実行しているし、いくつかの構造を作成した後にどのように見えるかです：

は、私にとって非常に似ています。
