ExcelToCI under HTTPS with SSL certificate errors

One of our customers was trying to use an ExcelToCI template to load data in PeopleSoft environment which could only be accessed through HTTPS. However, as the certificate in the web server was expired, ExcelToCI would error out whenever the user wanted to create a new template or submit the data to the database.

Obviously, this issue would have been solved by simply renewing the web server certificate, but the customer was not in a position to do this now and we had to seek an alternative solution.

Our solution was to modify the ExcelToCI macros to tell them to ignore SSL certificate errors. To do so, we had to do the following changes on the CreateCITemplate.sendSOAPRequest_GetCIShape() and StagingAndSubmission.sendSOAPRequest_SubmitToDB() functions:
  • Replace the following variable declaration:
Dim xHTTP As XMLHTTP

by

Dim xHTTP As New MSXML2.ServerXMLHTTP40
  • Replace the following variable initialization:
Set xHTTP = New XMLHTTP

by

Set xHTTP = New MSXML2.ServerXMLHTTP40

  • Add the following line before calling the Send method:
xHTTP.setOption 2, 13056 'Ignore all SSL errors


The SetOption call is actually telling the Send method to ignore any SSL certificate error.

I had a similar problem but just renewed the SSL certificate (it was much easier) but i've bookmarked this incase I have different circumstances of clients in the future

That's true, although this particular customer said it would take some weeks to get the certificate renewed because of internal approval procedures.
It's clear this is just a workaround.

This saved me a lot of searching today. Thank you.

Javier,

We receive this error but the description is different (its just the number again). Also our certificates are definitely not expired.

This works in IE6 but breaks in IE8. Any idea on what this could be?

Javier Delgado said...

Michael,

I'm not sure what you mean, as IE is not involved in the process.

However, depending on the Excel version, the MsXML objects may have different properties. Still I don't see any relation with IE.

Thanks!

This is true even if the client said it would take weeks to get the certificate renewed because of internal approval procedures.

If your SSL certificate is valid for the hostname, not expired and was issued by a trusted root certificate authority you might well be fine. Just change the parameters on the Connection tab and you’re good to go.

An SSL Certificate helps Web site visitors protect sensitive information and get a better idea of who they are trusting with it.

A good number of those things make sense to me.

If the SSL certificate is valid for a hostname, not over, and has released a trusted certification authority, you may very well be in order. Only a change in the Parameters tab and you're done.

Well if you have got SSL Certificate from trusted authority reseller, then you might not get any problems in renewing the certificate.
