Please excuse me for being so stupid but I just can't figure out how to find
the master and user keys.Everything I've read so far say's that they are in plain text in the target.The program is protected with Crypkey v5.4 .Please tell me what I should be looking for.

Look for functions that are called in the program.
The keys are sent to the DLL to verify the parameters needed.
Typically they are in plain sight in the code since crypkey think they are very secure.
If they are not in the string listing try just looking at the exe itself via a hex editor etc.

Also try dumping the program and searching through the dump for the keys just in case they decided to run another exe protector over the top.

Thank you, I found them in a file burried in a windows system32 folder.Now all I have to do is find the key level and option bits.
