Given what is in the description of shc in the link you posted, the purpose of shc is to hide cleartext passwords written into shell scripts. But, the keys for unencrypting the script are built into the script, so anybody that has access to the website you posted that can also read the script can decode it with a little bit of C programming and see whatever is in your script. If you think that using shc will keep someone from being able to read your script, that is only true if you don't have any experienced users on your system or make the files unreadable by unauthorized users. (And if the files are unreadable by unauthorized users, you don't need to use shc.) I don't see that shc does anything for you but make it harder to maintain your script. Furthermore, you should NEVER UNDER ANY CIRCUMStANCES put a cleartext password in a shell script nor put a cleartext password as a command line argument when invoking a process. (Doing this makes it possible for any user to see the cleartext password for a period of time that lasts somewhere between a few nanoseconds and the time until the system is rebooted.)
