md5加密dll
『壹』 MD5做成DLL插件加密安全嘛
樓上是SB
加密三次可以的了，想知道加密多少次要費很多時間，解密的不一定知道是用MD5加密的啊，你如果還不肯定安全不，你可以第一次加密後取中間幾位數再加密一次這樣就更安全了。
『貳』 delphi 中的 MD5 加密怎麼用
1.在Delphi自帶的Indy控制項中其實是提供了MD2,MD4,MD5對象的，可以直接使用來完成MD5的簽名演算法。不需要DLL或是Pas。 2.在Uses單元中引用 IdHashMessageDigest,IdGlobal, IdHash 單元，再寫如下代碼即可以達到MD5的實現。
『叄』 C#中dll該如何聲明及調用
[DllImport("twain_32.dll", EntryPoint="#1")]
private static extern TwRC DSpxfer( [In, Out] TwIdentity origin, [In] TwIdentity dest, TwDG dg, TwDAT dat, TwMSG msg, [In, Out] TwPendingXfers pxfr );
[DllImport("kernel32.dll", ExactSpelling=true)]
internal static extern IntPtr GlobalAlloc( int flags, int size );
『肆』 幫忙破解一個MD5,
幫你跑了，沒跑出來。。。。。。。
不過給你提供一個方法，來破解綠壩：
綠壩的管理密碼，通過類似於MD5的加密之後，儲存在WINDOWS/system32/kwpwf.dll文件中，搞笑的是該文件並沒有收到任何程序的保護，單憑一記事本就可以大改其中內容。我們只要把知道密碼的綠壩的WINDOWS/system32/kwpwf.dll文件中的內容復制到不知道密碼的那個綠壩的WINDOWS/system32/kwpwf.dll下，就相當於改變其密碼了。也就是說，我們只要把WINDOWS/system32/kwpwf.dll的內容改為「」，那麼綠壩的管理密碼就變回了默認的112233。
也就是說你破解它的時候，就將此MD5散列""替換掉原先的，不用的時候在替換回去即可~
希望對你能有所幫助。
『伍』 求md5批量加密的工具，要能保存加密出來的密文，密文與明文對應的....生成資料庫也行！
