In order to calculate the SHA1 checksum of a downloaded file, I could type

/usr/bin/openssl sha1

in Terminal and then drag there the file which I want check. To make it simpler, one could enable a Context Menu item for this action.

What is the best way to create such item in Mac OS X 10.6? A detailed answer is appreciated, because I don't have good experience with AppleScript, etc.

Step by step

Open Automator
Create new service
Choose to receive selected Files and Folders in Finder
Add action Run Shell Script where your bash command is /usr/bin/openssl sha1 "$@" and you pass input as arguments

How can I get the output? Preferably in a Growl pop-up or a message window/dialog.
