Default Paypal Pro Integration in Classic ASP

Hi,
 I have to integrate Paypal Pro with a website developed in classic ASP. And in that I have to use API certificate and not the API signature.
  My query is how to use API certificate with NVP method. I encrypted the API certificate and installed in my PC. and the i made following changes in hash_call function in the ASP NVP samples that paypal provided.

Function hash_call ( methodName,nvpStr )
On Error Resume Next
    Set objHttp = Server.CreateObject("WinHTTP.WinHTTPRequest.5.1")
 nvpStr = Server.URLEncode("METHOD")&"=" &Server.URLEncode(methodName) &nvpStr &"&" &Server.URLEncode("VERSION")&"=" &Server.URLEncode(gv_Version) &"&" &Server.URLEncode("USER") &"=" &Server.URLEncode(gv_APIUserName)&"&PWD=" &Server.URLEncode(gv_APIPassword)

    Set SESSION("nvpReqArray")= deformatNVP(nvpStr)
    objHttp.open "POST", gv_APIEndpoint, False
    objHttp.SetClientCertificate "LOCAL_MACHINE\my\" & gv_APIUserName
gv_APIUserName
    WinHttpRequestOption_SslErrorIgnoreFlags=4
    objHttp.Option(WinHttpRequestOption_SslErrorIgnore Flags) = &H3300


    If gv_UseProxy Then
    'Proxy Call
    objHttp.SetProxy gv_Proxy, gv_ProxyServer& ":" &gv_ProxyServerPort
    End If

    objHttp.Send nvpStr

    Set SESSION("nvpReqArray")= deformatNVP(nvpStr)
    Set nvpResponseCollection = deformatNVP(objHttp.responseText)
    Set hash_call = nvpResponseCollection
    Set objHttp = Nothing
    If Err.Number <> 0 Then
    SESSION("ErrorMessage") = ErrorFormatter(Err.Description,Err.Number,Err.Sour ce,"hash_call")
    SESSION("nvpReqArray") = Null
    Response.Redirect "APIError.asp"
    Else
    SESSION("ErrorMessage") = Null
    End If
End Function

Function deformatNVP ( nvpstr )
On Error Resume Next
    Dim AndSplitedArray,EqualtoSplitedArray,Index1,Index2, NextIndex
    Set NvpCollection = Server.CreateObject("Scripting.Dictionary")
    AndSplitedArray = Split(nvpstr, "&", -1, 1)

    NextIndex=0
    For Index1 = 0 To UBound(AndSplitedArray)
        EqualtoSplitedArray=Split(AndSplitedArray(Index1), "=", -1, 1)
        For Index2 = 0 To UBound(EqualtoSplitedArray)
            NextIndex=Index2+1
            NvpCollection.Add URLDecode(EqualtoSplitedArray(Index2)),URLDecode(E qualtoSplitedArray(NextIndex))
            Index2=Index2+1
        Next
    Next



    Set deformatNVP = NvpCollection
    response.write("tt=" & err.number)
    If Err.Number <> 0 Then
    SESSION("ErrorMessage") = ErrorFormatter(Err.Description,Err.Number,Err.Sour ce,"deformatNVP")
' response.Write("hi" & err.number & "ss=" & err.source)
' response.End()
    Response.Redirect "APIError.asp"
    else
    SESSION("ErrorMessage") = Null
    End If
End Function

But this is not executing. Either it gives "Security Error in hash function " or "Subscript out of range " deformatNVP function.


If any one have any sample code regarding NVP method using API certificate in classic ASP, then let me know. As I got stuck here and i m getting no way to proceed.
It's urgent to complete it.

Any help will be greatly appreciated. Thanks in advance.
