Convert OS X Keychain exported entries into logins for 1Password import

README

These two files should help you to import passwords from mac OS X keychains to 1password.

Assumptions:
1) You have some experience with scripting/are a power-user. These scripts worked for me
   but they haven't been extensively tested and if they don't work, you're on your own!
   Please read this whole document before starting this process. If any of it seems
   incomprehensible/frightening/over your head please do not use these scripts. You will
   probably do something Very Bad and I wouldn't want that.
2) You have ruby 1.9.2 installed on your machine. This comes as standard with Lion, previous
   versions of OS X may have earlier versions of ruby, which *may* work, but then again, they
   may not :-) You can check by opening the terminal application and typing ruby -v

Instructions:

0) Save keychain.rb and click_allow.scpt in your home directory.

1) Enable full GUI scripting by going to the Universal Access System Preference Pane
   and checking "Enable access for assistive devices"

2) Open the Terminal application and run the following command:
   security dump-keychain -d login.keychain > keychain.txt

(If you have multiple keychains you should repeat this whole process once from step 2 onwards for
 each one. You will have to change 'login.keychain' to 'foo.keychain' or somesuch.)

3) When you run the above command, the system will ask for permission to use your keychain. If you
   have a separate keychain password/have paranoid settings on your keychain, you may need to enter
   a password now. Otherwise, you will be presented with a dialog box asking you whether you want to
   allow permission to access the first item in your keychain. You will be asked this once for every
   item in your keychain (zzz). This is where the other file comes in:

4) Find the click_allow.scpt in your home directory using Finder, double click it. It will open in
   the AppleScript editor. Click the run button. If all is well, the script will click the "Allow"
   button for you lots of times until all of your keychain entries have been exported. Shouldn't 
   take more than a few minutes even for hundreds of entries.

5) When that finishes, go back to the Terminal window and run the following command:
   ruby keychain.rb keychain.txt | sort > keychain.csv

6) If all is well, that command will finish very quickly without any message. If it spouts an error
   at you, sorry, you'll have to fix the script, something's broken. Otherwise you should try opening
   up keychain.csv in your favourite text editor (TextEdit? <shiver>) to make sure it contains a list
   of keychain entries. 

7) Fire up 1password and choose File>Import. You want to import keychain.csv as a "CSV or Delimited Text"
   file. The process is fairly self-explanatory, make sure you select "comma" as the delimiter at the 
   appropriate point. You will have to tell it which columns correspond to which fields (this is pretty 
   obvious) and you should check that there are exactly five columns. If you're seeing more than five
   columns, one of your values contains a rogue comma and you need to fix it manually before you import the
   file or it won't work. The 5th column is optional - it's the last modified date for the keychain entry;
   unfortunately 1password won't let you import this as the "modified date" for the password but I put
   it in a notes field just in case since I often find it helpful to know when a password was set.

8) IMPORTANT: You now have 2 files on your hard disk that contain unencrypted passwords. You need to delete
   these securely if you are concerned about the possibility that someone might get your passwords. You have 
   two options. The easy option is to use Finder to move them to Trash, and then Secure Empty Trash. If you 
   are one of these funny people who likes to use their Trash Can as a temporary storage location and don't
   want to empty it, you can go back to the terminal and issue rm  keychain.csv keychain.txt, and then fire up Disk
   Utility and use the "Erase Free Space" command on the relevant hard disk to securely blank all the free
   space on your drive (this may take some time). NB: If you have an SSD drive in your computer there will be
   no Secure Empty Trash (only plain Empty Trash) and there will be no "Erase Free Space" in Disk Utility.
   This is because some SSDs delete things much more permanently than traditional hard disks by default, so
   these commands are redundant. Simply emptying the trash/rm-ing the file from the terminal will suffice in
   this case.

Acknowledgements: The original ruby script was written by Morgan Schweers of https://github.com/cyberfox. I've merely fixed bits that didn't work for me, and added the script to push the Allow button + this documentation.

Yup, I get the same error

same error here
