Please explain to me why you think Crypkey is much harder than Armadillo. I have experience in both protections and I believe Armadillo is certainly better, protection wise.
To unpack a Crypkey 6.0 app requires nothing more than simple debugger and 5 minutes of your time. Look for one jump and dump the app there. Not even the import table is messed around with.
Crypkey 7.0 is better, with an armadillo-like encrypt/decrypt on demand, but still takes no more than 30 minutes to unpack.
The authorisation keys for app's protection with Crypkey 6 and 7 are very difficult to break or copy. However, the demonstration version of the sitekey generator is very easy to break and allows you to generate these keys with ease. I'll estimate it didn't take me 45 minutes to change the demo sitekey generator into the full version.
Oh, and BTW, you can find current trial versions of there software if you know where to look...
