The hasp 4 uses decryption of data in real time. For this the hasp envelop uses a decryption key which unique for all hasp. Though i can find this key by dumping the file in runtime and searching it in hex viewer. My question is that, is there any other way to find this encryption key, like a usb sniffer or a hasp monitor ?

now.have some Tools can Emu hasp 4 's data,
can dump all data and auto emu hasp

the tools can convert dump data to reg .so can emu the hasp.
in www.exetools.com/forum can find it .

Can u be more specific about it ?? I mean have u ever used an emulator which can emulate hasp 4 ??

Yes, i emu it . but the tools isn't written by me ,so some part i don't no more.

if you have fun, give me the mail. i can mail you.
