升级MD5.ASP,打造完全动态不重复的安全加密代码
做一个完全动态的密码,让相同的密码生成不同的结果
密码aaa经过第一次运算后结果为:
jlce1d65ec3b91556234879c9db8f6da1123
第二次:
hjmnbe0d01cc1fbd3e18ae7431fa52fb3ce4
第三次:
grttb05901915e121d83ebefad7e809ef1b0
... ...
当然,亦可还原比较
以下我根据动网MD5函数修改后的代码,
\'=======================================
\'word 要加密的字符串
\'返回加密后的 word
\'例:response.write Md6(\"aaa\")
\'www.knowsky.com
\'=======================================
Function Md6(Word)
Dim Random, RandomNum, reRandom, reWord
Randomize
Do While Len(Random) < 4
RandomNum = Chr(25 * rnd + 97 )
Random = Random & RandomNum
Loop
reRandom = Md5(Random)
reWord = Md5(Word)
Md6 = LCase(Random & Md5(reRandom + reWord))
End Function
\'=======================================
\'Wrod 需要验证的字符串,OldWord 加密后的原字符串
\'返回比较后的结果,如果相等返回True,反之False
\'例:pwd=“aaa“
\' old_pwd=“grttb05901915e121d83ebefad7e809ef1b0“
\' if Md6Back(pwd,old_pwd)=TRUE then
\' ... ...
\'=======================================
Function Md6Back(Word, OldWord)
Dim Random, RandomNum, reRandom, reWord
Random = Mid(OldWord, 1, 4)
reRandom = Md5(Random)
reWord = Md5(Word)
If OldWord = Random & Md5(reRandom + reWord) Then
Md6Back = True
Else
Md6Back = False
End If
End Function
