It sounds a bit cheesy but I can’t find any usable solution on how to encrypt Linux/Unix shell script in order to protect it’s source code when it’s still executable.
There was a post here about how to protect shell scripts, but I found SHC bug. Just run script that is encrypted with shc and execute command ps ax and you’ll see full source code at ps‘s output (newline characters will be replaced with “?” symbol). Because of this fact I can’t use SHC anymore and looking for alternative solution.
It would be very appreciated if you suggest a way how to solve the issue. THANK YOU, mates.

Thank you in advance…
Probably wzshSDK is the only one which can do the job.
Thanks, UnixFan! I’ll try it and post the results here..
UnixFan, it seems that wzshSDK is no longer maintained and I didn’t find a way to get and try it 😦
I’ve written an e-mail to the author and still wait for his reply. Help is still appreciated 😉
Update regarding wzshSDK: author’s e-mail address is unavailable (my e-mail can’t be delivered to it). No luck today…
