[HOW TO] Set password for .rar file

I've knew how to set password for .rar before, but today my friend ask me bout that. I said I'm forget.. :D
then I give her promise to try, after a view of trial I find the way,. just take a look:
for the first time decide the file that you wanna make .rar (if there files you can put to the folder) and the right click and choose Add to archive. 

 at the archive name and parameters choose the advance tab, click "set password" and set your password for the .rar

then click "Ok" twice, and your .rar file was made. (in my desktop Penguins.rar)

And you can test the rar by click on file in your rar.

tadaaaaaa,... you have the .rar file with the password.
