Encrypting my .SH file to prevent ppl from CATing the contents

[dreamaz]

How can i encrypt/compile this so that people cant CAT my .sh file?

I see some other scripts on our system with a .sh.x and when i cat it its all encrypted

Any ideas?

Thanks

Hi

No kidding. If you can not read a file, then nether the shell can. Those files probably are compressed and there is one command in "clear", which uncompresses the content and passes it to the shell.

If you want to make scripts unreadable then your friend is sudo (assuming you have root access)
[ol]
[li]Create the script, for example myscript.ksh in /usr/local/bin[/li]
[li]chmod 700 myscript.ksh - the script is now only readable by root.[/li]
[li]Add the line to the sudoers file

ALL myhost=/usr/local/bin/myscript.ksh

[/li]
[/ol]
I use a similar method to protect scripts which have hardcoded passwords (ugh!) in them. For added security you might want to create /usr/local/secure_bin with 700 permissions to store these files.

It's far from perfect but it's simple to implement.
