gopass-chrome-importer Build Status

A simple tool to import Chrome passwords into gopass.

How it works

gopass-chrome-importer parses the .csv file that can be exported from chrome and loops over each entry in the list which provides

  • a name (of the entry)
  • the url
  • the username
  • the password

Determining the secret file path

  1. Since not only passwords for websites are stored in chrome all entries are divided into categories which are later used as subfolders when creating the actual secrets in gopass.
  2. Next the url is simplified based on the category to provide a human readable name for the secret.
  3. To improve usability with the gopass chrome and firefox plugin the username is used as the file name of the secret.
  • website
    • the url is stripped down to only contain the domain (and all subdomains) f.ex. import/website/smile.amazon.com/your@mail.com
  • ip
    • since saved passwords of IPs can be duplicates based on the network you are in these passwords are sorted into their own category and the url is stripped to only contain the IP (v4)
    • IPv6 is currently not detected and would be handled as a website
  • android
    • the url is stripped down to only contain the package of the app f.ex. import/android/com.paypal.android.p2pmobile/your@mail.com

Secret file content

The first line of a secret is always supposed to be a password with additional info added below separated by a --- divider. When a username is available it will be added to the additional info section which can then be used by the chrome and firefox plugin:

mypassword1234
---
user: myuser

If no user is available just the password is written to the file:

mypassword1234

Creating the secret

Since gopass does not provide a non-interactive way to create or modify secrets the fact that secrets can not only be edited but also created using the gopass edit command is used to work around this (security related) limitation. When executing gopass edit /some/secret gopass creates a temporary decrypted file inside /dev/shm for this secret which is then passed to $EDITOR. gopass-chrome-importer uses this to its advantage and writes itself into that env variable to process the temporarily decrypted file. First of all the existing file is checked to prevent overwriting of existing secret data. If those checks succeed the secret is written to the file in the form described above. After that gopass encrypts the temporary file with the selected recipients and (if a remote is available) pushes it to the server.

Installing

Now that you hopefully have a good understanding of how this tool works lets actually try it out!

Since this package is not completely without dependencies it is recommended to install it inside a virtualenv:

python3 -m venv ~/path/to/new/virtual/environment
source ~/path/to/new/virtual/environment/bin/activate
pip3 install gopass-chrome-importer

Usage

For basic usage the import command should be all you ever need. gopass-chrome-importer has a couple of parameters to customize the import result and you should take a look what they offer before actually importing anything. For a quick overview call:

gopass-chrome-importer import --help

Dry Run

To test things out before actually importing passwords into gopass (and possibly pushing them to origin) you can use the -d or --dry-run option. This will only output secret paths and contents where passwords are masked as asterisks to give you an idea of what would happen.

An example output would look similar to this:

Would import: /import/ip/127.0.0.1/joe
******
---
user: joe

Would import: /import/ip/192.168.0.1/admin
********************
---
user: admin

For safety all examples on this page will include this option.

Set the path to the chrome password export .csv

To set the path to the export.csv file just use the -p or --path option:

gopass-chrome-importer import --path "~/Downloads/Chrome Passwords.csv" --dry-run

Changing the base import path

By default gopass-chrome-importer will import secrets into an import/ folder. To change this simply use the -gb or --gopass-basepath option:

gopass-chrome-importer import --path "~/Downloads/Chrome Passwords.csv" --gopass-basepath /test/ --dry-run

--yes

By default gopass will ask you some questions when creating a secret like which recipients to use for this secret. For large lists of passwords this can be quite a hassle. gopass has a built in --yes option to circumvent this by always using "Y" or the default (if yes is not an option). This parameter can also be used (in addition to -y) in gopass-chrome-importer and will just pass it on to gopass.

gopass-chrome-importer import --path "~/Downloads/Chrome Passwords.csv" --gopass-basepath /test/ --yes --dry-run

Overwrite existing passwords/file contents

When gopass-chrome-importer tries to save a password in a file that already exists and that file is not empty it will (by default) not change the file contents to prevent accidentally overwriting of existing passwords.

You can force gopass-chrome-importer to ignore this check by using the -f or --force option.

Although your existing passwords are backed up in a git and (hopefully) synced to a server side backend be careful and think twice before using this option.

gopass-chrome-importer import --path "~/Downloads/Chrome Passwords.csv" --gopass-basepath /test/ --yes --force --dry-run
