WindowsNT/2k密碼到雜湊的實現演算法(轉)

WindowsNT/2k密碼到雜湊的實現演算法(轉)[@more@]

　　NT/2000的密碼雜湊也叫OWF，其實這個雜湊的作用很大，任何密碼都會先生成雜湊進行儲存，在網路認證的時候，也會使用雜湊。

　　但是關於NT/2000的密碼雜湊雖然有很多的介紹，但是卻缺乏具體的演算法，影響了對於其演算法安全性的研究，這裡就是透過反彙編獲得的密碼到雜湊的實現。

　　NT/2000的密碼雜湊其實由2部分組成，一部分是透過變形DES演算法，使用密碼的大寫OEM格式作為金鑰（分成2個KEY，每個KEY7位元組，用0補足14個位元組），透過DESECB方式獲得一個128位的金鑰，加密特殊字串“KGS!@#$%”獲得的一個16位元組長度的值。另一部分則是使用MD4對密碼的UNICODE形式進行加密獲得的一個雜湊，下面就是具體的演算法程式碼，提供給大家做進一步深入的研究：

　　//注：DES的演算法與標準DES的演算法有如下不同

　　//與標準DES的SPBOX不同

　　//與標準DES的ECB生成演算法不同，DESKEY不同，標準的是生成64位位元組，而他是生成128位位元組

　　//標準的DES一次是8位元組塊加密8位元組再迴圈，而他是16位元組一次

　　//關於MD4的實現，我這裡沒有標準MD4的演算法實現和說明，但是有MD5的，按照MD4與MD5的區別中，好象演算法還是有很多改變。

　　//因為按照標準的MD5的說法，每輪當中的每次計算，除了引數不同，函式演算法是一致的，但其實他的實現是不同的。
