LabVIEW Remote Panel

[Alan Cheuk]

I am using LabVIEW Remote Panel to remote control a VI program. The VI interface will send to me via a htm file and I control the program through a Web browser. Does anyone know any method to encrypt the content of the htm file? (I want to ensure the data and the program interface are protected)

Thanks

One way is to block ip's and vi's. You can block access to your remote front panel under tools>>options>>web server:IP access and under web server:visible vi's. Both of these will allow you to restrict who can see your data. As far as encryting you data remote front panels is probably not your best option. Maybe create a sender and receiver vi and use data sockets. You can encrypt and decrypt the data on either end. hope this helps.

There are a lot of third party tools that will allow you to encrypt the HTML file. Actually there is nothing in the HTML file generated by Labview, because the run time Engine does the Magic.

Anyway I use HTMLock which can be purchased for $25. There are some freeware tools too. I like HTMLock because you can pass your HTML file once and that encrypts it. On the second Pass I implement Password protection. So now if you go to the web Page, It asks for Password. If you try to see the source for this page, it is encrypted. If you know the password, you can view the VI and again the source is encrypted.

You can try running a more powerful webserver like apache (instead of the labview webserver) and configure it for secure http.

Unfortunately, Labview VI will not work remotely with any other webserver. The remotepanel will give the message "Server does not support remote panels".

Here is a link for the same...

Hello Mache,

Thanks for your help. You said that HTMLock can protect my htm file with password.
Will the content of the htm file is encrypted between transmission? Or there is only a password to prevent other people to contect to the link of my htm page?

Thanks

However you want to set it up. In the first pass, you can do a source lock which encrpts your HTM file. In the second pass you do Passwrod Lock and now you need to supply the password to see the web page. I have a public web page which is using this method. If you want to see it, Send me an email and I can let you in on the password.
