I'm looking for a solution to perform file encrypting and signing. This would be done on the client side, and signature check and decryption on the server side.
Some details:
This should work for any kind of file (the signature should be "attached" to the file, not inside it like with PDFs)
At least the server side should be Java base...
Hi All,
I am working on a little Hardware interface project based on the Velleman k8055 board.
The example code comes in VB.Net and I'm rewriting this into C#, mostly to have a chance to step through the code and make sense of it all.
One thing has me baffled though:
At one stage they read all digital inputs and then set a checkbox ba...

Hi there,
i figured I must use a MEX-File to output Digital pulses in a loop (40 kHz) from Matlab to my DAQ-Board, I have some APIs from the DAQ-Board vendor, but I really dont know if they are useful.
