USB control under ColdFusion

Hello folks, I hope to post in the right place. I am developing in OpenBluedragon under CentOS 5 Linux platform. To protect my app, I have been told to use a USB  "dongle" which behaves as a serial RS232 port (that's  what has been said to me)., on which read and write simple patterns. Don't know where to start from. Should I look for a CFC component? I haven't found yet Can anybody give me a clue? Thanxx Riccardo Cecinati

There might be a way to do it from Java, but my first thought would be that you can just use CFExecute to 'cat' to and 'echo' from the /dev/ttyXXX file... -- Tom Chiverton Developer Tom.Chiverton@halliwells.com 3 Hardman Square, Manchester, M3 3EB **************************************************** This email is sent for and on behalf of Halliwells LLP.

in my (limited) experience, talking to USB devices from Java isn't usually much fun, but if it's exposing itself as a serial port then I'd imagine it will be easier.  If the device manufacturers have an API for Java, great (check their site).  If they don't, and want to make this work ASAP, you may want to quick try to use a serial to socket server, and then simply "talk" to that local port.  That isn't the most elegant solution, but may be the fastest to get up and running. ~Simon Simon Horwith CTO, Nylon Technology http://www.nylontechnology.com blog - http://www.horwith.com riccardo.cecinati@poste.it wrote: ----- Excess quoted text cut - see Original Post for more -----

Riccardo, I wouldn't think a USB dongle would be an effective means of protecting an app written in a script based language like ColdFusion.  I imagine it would be trivial to circumvent any such security with simple CF code changes.  I'd be interested in hearing about any solutions you come up with.

I agree with David -- Merely putting a file on USB storage, is just a file and can be read from/written to like any other file. However, the dongles that are spoken of are not typically of the storage variety. This is based on what kind of hardware class (device) they show up as to the OS. I believe what you're after is some sort of crypto token device. AKA a hardware token. (like this: http://www.rockey.nl/en/products/rockey-products.html) We could go back and forth all day, but since CF is an interpreted, script-based language, you really couldn't stop someone from subverting any hardware tokens, whether or not they were USB Storage or USB Crypto keys.

I would probably look into C# as serial port communicator and if it works for you, later you just can integrate DLL with CF, so CF will be able request/response via your .NET DLL. Here is the tutorial for C# serial port communication: http://www.dreamincode.net/forums/topic/35775-serial-port-communication-in-c%23/ OR using JAVA: http://www.java2s.com/Code/Java/Development-Class/OpenaserialportusingJavaCommunications.htm CF is not really good tool for that task.
