Description

Previous caesar cipher obfuscator did not work for unix systems running sh (rather than bash) within sandcat (which seems to be the default), and for both sh and psh executors would only print out the command at the end (rather than actually execute it). It also had some issues with special characters that could cause the command to crash. I have made changes so that the caesar cipher only rotates letters within the original command, as well as escaping out special characters for each executor, so that these issues do not arise.
