How to reuse old LPT HASP key?

Question

I've got a bunch of old LPT HASP keys. 1

Is there a way to interrogate these? Can I use these HASP Keys as a source of random values or something like that?

Maybe there is a better way to give those things a second life?

Answer 1

I can explain only about HASP keys.

If you got these keys along with the purchase of any software then you can't do anything with them. If you are a software developer and got these keys for protection own software then you should have a USB Master key or two private passwords. Having them you can store data inside these keys or encrypt/decrypt any data. For this, you need to use HASP API: https://www3.safenet-inc.com/support/hasp/hasp4/Win32api.aspx
