Diceware Passphrase to Keychain and Clipboard 1.1

**Function:** Using the Diceware
method for strong passphrase generation, this workflow generates a 10
word passphrase from the Diceware
word list. The passphrase is inserted into your Keychain and
copied to the clipboard.

**Update 1.1**

1. Added CocoaDialog dialog for user to enter account name associated
with the password; the dialog includes a default answer of your OSX
short username. The selected account name is entered into the Keychain
with the password.

2. Replaced the Applescript dialog notification for successful pasword
generation with a Growl notification to reduce user interaction with
windows.

Requires: CocoaDialog
installed in /Applications and the Growl Automator action.

**Notes**: For those who use OpenPGP,
Hushmail and other similar
encryption tools, a strong passphrase is critical for security. The Diceware
method is a very secure way of generating such passphrases with high
entropy. The default passphrase in this workflow is 10 words, which
gives a passphrase that matches the 128 bit security of Hushmail and OpenPGP.

The über-paranoid will not want to use this workflow as it is based on
the Perl implementation of rand() - thus the selection of words from
the word list is not totally random. Also, the copy to the clipboard
step is for convenience and is not a secure way of handling
passphrases - folks may want to delete the line:

echo $pwd |
pbcopy

from the Run Shell Script action in Step 2 if this is an
issue [1].

However, for most real world purposes, this workflow is more than
adequate and has the advantage of directly inserting the passphrase
into your Keychain, rather than writing it down anywhere.

[1] If you edit this in Automator, ensure that in Step 1, the shell is
set to /usr/bin/perl...there is a bug in Automator that causes the Run
Shell Script action to default to /bin/bash when re-opening the
workflow regardless of what was set at last save.
