asp加密解密求解决求大神来啊。。。 1

Question

这是解密的执行代码，

    解密以后页面显示空白。
 a = "6-66-85-21-69-4-87-82-65-3-75-74-64-"


==================================================================================
<%
Function EnCodeY(sText)
Dim arrCode()
Dim sCode
sCode = Request.Cookies("ddd")("Qmxanman")

arrData = split(sText, CHR(-24151))

cntData = UBOUND(arrData) - 1
cntCode = Len(sCode) - 1

Redim arrCode(cntCode)

For i = 0  To cntCode
arrCode(i) = Mid(sCode, i + 1, 1)
Next

flag = 0
strResult = ""
For i = 0 To cntData
strResult = strResult & CHR(Cint(arrData(i)) XOR ASC(arrCode(flag)))
IF flag = cntCode Then
flag = 0
Else
flag = flag + 1
End IF
Next

EnCodeY = strResult
End Function

a = "6-66-85-21-69-4-87-82-65-3-75-74-64-"
response.write EnCodeY(a)&"<br>"

Answer 1

arrData = split(sText, CHR(-24151))

你的字符串分隔符是-，CHR(-24151)这个又不是-
==>arrData = split(sText, "-")

cntData = UBOUND(arrData) - 1
这个cntData就是-1了，你的For i = 0 To cntData这个循环就没有执行，那么不就返回空值了。
sCode = Request.Cookies("ddd")("Qmxanman")还有你的这个变量有值没用。。自己response.write输出看内容

改下面测试可以了，自己注意sCode

  Function EnCodeY(sText)
Dim arrCode()
Dim sCode
sCode = "123"'''''测试直接设置为1，自己注意这里cookie的值是否有
'sCode = Request.Cookies("ddd")("Qmxanman")'''''''''''''''''''''''''

arrData = split(sText, "-")'''''''''''''''''''''''''''''

cntData = UBOUND(arrData) - 1
cntCode = Len(sCode) - 1

Redim arrCode(cntCode)

For i = 0  To cntCode
arrCode(i) = Mid(sCode, i + 1, 1)
Next

flag = 0
strResult = ""
For i = 0 To cntData
strResult = strResult & CHR(Cint(arrData(i)) XOR ASC(arrCode(flag)))
IF flag = cntCode Then
flag = 0
Else
flag = flag + 1
End IF
Next

EnCodeY = strResult
End Function

a = "6-66-85-21-69-4-87-82-65-3-75-74-64-"
response.write EnCodeY(a)&"<br>"'===>输出7pf$w7f`r2yyq
