Hi All,

I want to make my script password protected.

i e: if somebody runs my script it should prompt for password.

Can somebody help me in to execute the same??

Thanks in Advance

hi,
I got a very simple idea.

Write something like this in the beginning of your script for the password checking.

...
ACTUAL="perftest"
read -s -p "Password: " enteredpass
echo ""

[ "$enteredpass" != "$ACTUAL" ] && echo "Sorry" && echo "exiting" || echo "Conti.."
...

Since you will be storing your password in your script itself, you have to protect your shell script by using shc.
Generic shell script compiler(shc) creates a stripped binary executable version of the script specified with -f on the command line. (shc encrypts shell scripts using RC4)

Hope this helps.

I am not very clear about shc,

Can you tell me how to make a sciprt as shc??

Well,
I have a post here,

Jadu's Workshop: How to protect a shell script

which will help you.

Hi,

I tried encryting a bash script, and I received the below error...

-bash: shc: command not found

Is there a different command to execute bash scripts??

reasonably simple password encrypter process:

you could use perl to crypt a password e.g.:

perl -e "print crypt('password','AA');'\n'"

then use perl in your script to check the password e.g.:

/usr/bin/perl -e "print 'match' if crypt('password','AA') eq 'AA6tQYSfGxd/A';"

and do the test / exit or continue with script piece

but as noted already this does not hide the contents of the script - for very basic security it'll do though...

achararun you have to get shc install in your box if ! present, get it from here, Francisco Rosales, home page
