Can you use SHC to obfuscate a script?
The way SHC works is actually pretty straight-forward. When using it to obfuscate a script, you have to re-compile the script for whichever OS you intend to run it on. What that means is, you cannot run the SHC compiler on a ubuntu box and expect the produced script to work on a Red Hat/CentOS box.
