OnePIF

OnePIF is a KeePass 2.x plugin to import 1Password Interchange Format (1PIF) files.

This plugin is OneVault sidekick. Check the Pros and cons of using OPVault vs. 1PIF section to decide which plugin is right for you.

This plugin was made using Dmitry Wolf's 1P2KeePass as a guide and example. There are copy-pasted bits of 1P2KeePass code I was lazy to rewrite myself.

Features and support

Brief list of features

  • The plugin imports:
    • Most item types available in 1Password 6 and 7: Logins, Secure Notes, Credit Cards, Identities, Passwords, Bank Accounts, Databases, Driver Licenses, Email Accounts, Memberships, Outdoor Licenses, Passports, Reward Programs, Servers, Social Security Numbers, Software Licenses, Wireless Routers, User-defined Folders.1
    • Legacy item types from 1Password 3: Email Account (v1), iTunes, MySQL Database, FTP Account, iCloud (a.k.a. MobileMe), Generic Account, Instant Messenger, Internet Provider, Amazon S3 (a.k.a. Amazon Web Services).
    • All template fields, web form fields and user-defined fields.
    • Previously used passwords list.
    • User-defined tags.
    • Favorite flag (as a tag).
    • Trashed items.
    • Custom user-provided icons2 (not the rich icons provided by AgileBits).
    • File attachments.
    • TOTP fields formatted for KeeWeb, Tray TOTP or KeeOtp.
  • Organizes items into the standard 1Password categories or using pre-existent user-defined folders.
  • Proper handling of line endings in multiline fields.
  • Customizable date formats: ISO 8601 or user locale.
  • Customizable address formats: one-liner, multi-line in a single field or one field for each address component.

(Un)tested and (un)supported file formats and platforms

  • The plugin was tested using files created in, and exported from, 1Password 3, 6 and 7 for macOS and 1Password 4 for Windows. Nevertheless the number of combinations for creating, updating, migrating and exporting vaults in different versions of 1Password derives in a whole universe of possibilities, so you might still find errors while importing a file.
    • Very limited testing was performed with 1Password for Families/Teams/Businesses vaults.3
  • All item types (from the above list in previous section) and template fields were tested.
  • The plugin was tested with KeePass 2.40+ running on Windows and KeePass 2.38 running on Ubuntu.

What's next

I expect to keep fixing bugs and adding some features. Here are some of the plans, in no particular order:

  • General error handling.
  • Log/summary of import errors.

Download and installation

You can get the latest release from the Releases page. To install, unpack the archive and copy its contents to the KeePass Plugins directory. As stated in the KeePass 2.x Plugins page the package mono-complete might be required on some Linux systems for the PLGX file to compile.

If you're using KeePass 2.08 or older, you'll have to build the DLL version of the plugin. See the Building and debugging section for instructions.

Pros and cons of using OPVault vs. 1PIF

Pros

  • OPVault is an almost perfectly documented format. This makes it highly improbable to come across a file that will fail to be imported. If it ever happens, a bug in the plugin is probably to be blamed.
    • 1PIF format is almost perfectly undocumented and, to make things worse, there's a whole spectrum of different things one can find inside 1PIF files exported from different 1Password versions.
  • OPVault is encrypted at rest (i.e. while saved on a disk) and only minimal parts of it are in plain text so you can rest easy knowing your secrets are safe. Nevertheless, the vault is decrypted in memory during the import process and the plugin code is probably not as secure as 1Passwords' so please use it in safe environments.
    • As you should already know from the big red legend while exporting them, 1PIF files are stored completely in plain text, including all the secrets, so you must make sure to scrub really hard to remove any traces of the file after using it.

Cons

  • You can't directly export vaults from 1Password in OPVault format. The OPVault format is used for synchronization between different instances of the software. To get your hands over an OPVault bundle you must set your vault to be synced, locate and copy the resulting bundle.
    • 1PIF files are easily obtained using the normal 1Password export function.

Building and debugging

Prerequisites

Before building the plugin you must either download and place a copy of KeePass software in the KeePass directory inside the solution directory, or adjust the paths all over the projects4 to point to your current KeePass installation.

The plugin depends on Newtonsoft Json.NET. If you're using Visual Studio, enable the NuGet automatic download and installation of missing packages in Tools > Options > NuGet Package Manager > General. If you're using MSBuild use the nuget restore command to restore dependencies before building.

Building the PLGX version

You don't have to actually compile anything, just build the PackagePLGX project which consists of only a few post-build commands. KeePass will compile the plugin code upon first load of the PLGX package.

Building the DLL version

Build the OnePIF project using the Release configuration and you're ready to go.

To install, copy the plugin DLL along with the dependecies and (optionally) the localization satellite DLLs to the KeePass Plugins path5.

Debugging

To debug the plugin, configure OnePIF project Debug settings to start the KeePass executable.

Disclaimer

This software is provided as-is without any warranty of any kind. I take no responsability or liability for any damage it may cause. If it breaks your data you can keep its pieces.

Vaults often contain very sensitive information. Thoroughly check imported data for completeness and correctess before deleting the original files.


1 Smart Folders are not supported since KeePass seems to lack a similar feature. ↩️

2 Only icons saved as image formats supported by .NET System.Drawing.Bitmap class, namely: BMP, GIF, EXIF, JPEG, PNG and TIFF. ↩️

3 Sample 1PIF files completely or partially failing to be imported are welcome to expand support. If they're from a real vault, don't forget to redact private information. ↩️

4 Currently the post-build event in the PackagePLGX project, the build output path and the reference to the KeePass executable in the OnePIF project are dependent on the KeePass installation path. ↩️

5 If you want to use the localization satellite DLLs and you're using KeePass version 2.40 or older, copy all the files to the root KeePass installation path. Otherwise it will try (and fail) to load the satellite DLLs as plugins themselves. ↩️
