how to create a labview interface to simulate a key hasp

[jok2]

hello,
I want to create a labview interface to simulate a hasp key.
 
if anyone knows how to thank you in advance for your help

Depends on the type of key, and if you want a physical or a virtual key.

[jok2]

it is a physical key

[jok2]

have you got an idea?

[Todd_Lesher]

Parallel port? If so, LabVIEW on another PC could possibly control the LPT there.

The question is highly unclear. Do you want a LabVIEW VI library to incorporate a Hasp license key into a LabVIEW application or do you want to simulate such a key?

In the first case you can either use the Hasp utility to wrap the built LabVIEW executable into a protected executable or access the Hasp provided DLL through the Call Library Node to query for a Hasp key and matching license info. The first is trivial and should give you enough protection from casual hackers, the second requires some experience with accessing DLL functions through the Call Library Node (which means at least some basic C programming knowledge).

If you really want to simulate a Hasp key I would recommend taking this up on a more suitable discussion board about security encryption devices and start to learn a lot about encryption and all that.

in reality I try to do a labview interface to communicate with the HASP key

[jok2]

do you know how do ?

Rolf already answered both sides of what you could do, with such one-liner short questions no one will be able to help you with anything as we wouldn't know enough details on what you're trying to do. You first mentioned that you want to "simulate" HASP key but then you mentioned that you want a LabVIEW interface to communicate with the HASP key - those two task are totally different/opposite.

You would have to give plenty more detail using plenty more words...

I apologize for not having been unclear.
I am French student internship in Canada and the company has asked me to create a LabVIEW interface to communicate with the HASP key.
Do you understand what I want?
this is the only information they gave me
