Exporting (iCloud) Keychain and Safari credentials to a CSV file

---

WORK IN PROGRESS

---

The Mac OS Keychains is great if you spend your time in the Apple-verse. When you decide to mix it up or move away, you will want to take your password with you. Here's a process and the tools for exporting it's content to a CSV file in the format “example.com,user,pass”. This portable format would be pretty easy to import into Dashlane, LastPass, 1Password or whatever.

Kudos to https://gist.github.com/rmondello for creating the first version of this.

Copy the iCloud Keychain into a local Keychain

One’s iCloud Keychain is stored on disk in a different format than a traditional keychain. To access the credentials, first create a traditional keychain and copy there the iCloud Keychain’s contents:

1. In the Keychain Access, go to File > New Keychain (⌥⌘N). You can save the new keychain to the desktop and call it something like "Big Keychain"
2. Choose the iCloud kaychain from the sidebar.
3. Select all the passwords.
4. Use "Edit > Copy" to copy them all.
5. Selected the new "Big Keychain" in the sidebar.
6. Use "Edit > Paste" to paste the copied passwords.

Keychain Access prompted me for the “Local Items” keychain password for every password I was pasting. In my case, this would have been over 200 times!

Automating typing the keychain password and clicking “OK”

Run the following script to take care of this:

set keychainPassword to the text returned of ¬
	(display dialog ¬
		"Your keychain password:" default answer ¬
		"" with hidden answer)

tell application "System Events"
	repeat while exists (processes where name is "SecurityAgent")
		
		# Wait until the Allow dialog opens before proceeding
		repeat until window "" of process "SecurityAgent" exists
		end repeat
		
		tell process "SecurityAgent"
			set value of text field 1 of window 1 to keychainPassword
			click button "Allow" of window 1
		end tell
	end repeat
end tell

Whatever process is running this script (Script Editor or a standalone bundle), it’ll need permission to “control your computer”.

After that runs, the recently-created local keychain should contain all of the passwords stored in iCloud Keychain.

Write all of the passwords from the keychain to a file

I grabbed a copy of Daniel Jalkut’s “Usable Keychain Scripting” utility to help with the next part, but someone more sane might turn to security.

I ran the following script to write the passwords out to disk:

set the logFile to ((path to desktop) as string) & "Passwords"
set keychainPath to "/Users/Dad/Desktop/dad.keychain"

-- write_to_file taken from http://www.macosxautomation.com/applescript/sbrt/sbrt-09.html
on write_to_file(this_data, target_file, append_data)
    try
        set the target_file to the target_file as string
        set the open_target_file to open for access file target_file with write permission
        if append_data is false then set eof of the open_target_file to 0
        write this_data to the open_target_file starting at eof
        close access the open_target_file
        return true
    on error
        try
            close access file target_file
        end try
        return false
    end try
end write_to_file

tell application "Usable Keychain Scripting"
    set keychainItems to get every keychain item of keychain keychainPath
    repeat with keychainItem in keychainItems
        set aServer to server in keychainItem
        set anAccount to account in keychainItem
        set aPassword to password in keychainItem

        set csvEntry to aServer & "," & anAccount & "," & aPassword & "
"

        my write_to_file(csvEntry, logFile, true)
    end repeat
end tell

There’s a lot that can be improved with this code. For instance, I could have used a consistent naming style between copied and non-copied code. If I took the time to look up an array or list "join" routine, the intent of the could could have been better communicated.

Here again, OS X’s Keychain wanted to do its job, prompting me to allow access for each of the 200+ items.

tell application "System Events"
    repeat while exists (processes where name is "SecurityAgent")
        tell process "SecurityAgent"
            click button "Allow" of window 1
        end tell
        delay 0.2
    end repeat
end tell

After that, I had my file. Inelegant, but it got the job done, and I had fun.
