string - 複数の暗号化された文字列を使用したXOR復号化

Question

問題は、それぞれ約100文字の暗号化された文字列が11個あることです。ここでは文字列を書いていません。完全な解決策は必要ないので、従うべき方法が必要です。

キー文字列とXORされた11個の文字列。暗号化キーはわかりませんが、そのうちの1つを復号化できるはずです。JavaまたはCで書くことができます。大文字はスペースに関する情報を提供する場合があります。（スペースを使用して小文字をxorする場合は大文字になり、その逆も同様です。）

どちらの方法に従うべきですか？何か提案はありますか？

Answer 1

誰も私の質問に答えなかったので、私は自分の質問に答えています。ここで：これにより回答が読みやすくなり、暗号の欠落部分を推測できます。
