Exporting (iCloud) Keychain and Safari credentials to a CSV file
After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.
This is the process I used to create a CSV file of his credentials in the format “example.com,user,pass”. This portable format would be pretty easy to import into 1Password or Safari in the future.
The way I went about this isn’t great; it opens up more opportunities for apps to control one’s Mac through Accessibility APIs, it writes plaintext passwords to disk, and it could use some cleaning up. A better approach might leverage the
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, I first created a traditional keychain with the iCloud Keychain’s contents. To do this, I clicked
File > New Keychain (⌥⌘N) in Keychain Access. In my case, I saved the new keychain to the desktop. I clicked on iCloud in the sidebar, selected all of the passwords, and copied them. I selected the new keychain I just created and pasted the 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”
I ran the following script to take care of this:
-- Taken from a comment by Mr. X on http://selfsuperinit.com/2014/01/20/exporting-icloud-keychain-passwords-as-a-plain-text-file/ set keychainPassword to "keychain password" tell application "System Events" repeat while exists (processes where name is "SecurityAgent") tell process "SecurityAgent" set value of text field 1 of window 1 to keychainPassword click button "OK" of window 1 end tell delay 0.2 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
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.
-- Taken from a comment by Mr. X on http://selfsuperinit.com/2014/01/20/exporting-icloud-keychain-passwords-as-a-plain-text-file/ 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.
