JavaScript スクリプトは静的 Web ページ暗号化を実装します

著者：Eve Cole 更新時間：2009-06-08 18:34:42

2 日前、静的 Web ページの暗号化について質問している人を見たので、次のコード

アイデアを書きました。

暗号化するとき:まずユーザーのキー A を md5 で B に暗号化し、次に B を使用してソースファイル S0 を XOR してターゲットファイル S1 を取得します。、S1をjs変数に保存します。

復号時：鍵を要求し、暗号化と同様の動作を行います。

md5を使っているので鍵がないと解読できないと個人的には思っています(暴力を除く)

試してみましょう（笑）:

ソースコードは次のとおりです。
