## Fork information
This repository is a fork of [davidnemec/bitwarden-to-keepass](https://github.com/davidnemec/bitwarden-to-keepass).
They did all of the work, I just added the custom URL functionality and created a Docker repository. All props to [davidnemec](https://github.com/davidnemec/)!
## Features
- Exports Bitwarden vault items to KeePass format (.kdbx)
- Supports:
- Logins with usernames and passwords
- TOTP seeds and settings
- Multiple URIs (including iOS and Android app identifiers)
- Custom fields (text, hidden, boolean)
- File attachments
- Secure notes
- Nested folder structures
- Maintains folder hierarchy from Bitwarden
- Ensures unique entry names by appending item IDs when needed
- Handles custom Bitwarden/Vaultwarden instances
## Usage
### Environment variables available
- `DATABASE_PASSWORD` (optional): The password you want your KeePass file to have. If not set, the script will ask for a password interactively.
- `DATABASE_NAME` (optional): The name you want your KeePass file to have. If not set, it will default to `bitwarden.kdbx`.
- `BITWARDEN_URL` (optional): A custom Bitwarden/Vaultwarden instance URL. If you are using the official https://bitwarden.com, you can leave this blank.
- `DATABASE_KEYFILE` (optional): Path to a key file for additional KeePass database security.
### Backup location
All backups will be written to `/exports`. You need to mount that volume locally in order to retrieve the backup file.
### Running with Docker
The simplest way to run the tool is using Docker:
```sh
docker run --rm -it -v ./exports:/exports rogsme/bitwarden-to-keepass
```
**Important Docker flags:**
- `--rm`: The container deletes itself after running (prevents credential leakage)
- `-it`: Enables interactive mode (required for credential input)
- `-v ./exports:/exports`: Mounts local directory for the KeePass file output
### Interactive prompts
The tool will prompt for several pieces of information:
1. KeePass database password (if not set via environment variable):
```sh
DATABASE_PASSWORD is not set
Keepass DB password [input is hidden]
```
2. Bitwarden credentials:
```sh
Email address: your@email.com
Master password: [input is hidden]
```
3. Two-factor authentication (if enabled):
```sh
Two-step login code: 123456
```
### Export process
You'll see progress information like this:
```sh
Generating KeePass file /exports/bitwarden.kdbx
2024-02-20 15:12:54 :: INFO :: KeePass database does not exist, creating a new one.
2024-02-20 15:13:20 :: INFO :: Folders done (1).
2024-02-20 15:13:36 :: INFO :: Starting to process 999 items.
2024-02-20 15:13:36 :: INFO :: Saving changes to KeePass database.
2024-02-20 15:13:43 :: INFO :: Export completed.
```
The script automatically locks your vault and logs out:
```sh
Your vault is locked.
You have logged out.
KeePass file /exports/bitwarden.kdbx generated successfully
```
### Retrieving the export
Your KeePass file will be in the mounted exports directory:
```sh
ls exports
bitwarden.kdbx
```
## Known limitations
- Does not support credit card or identity items
- Requires interactive login (no persistent sessions)
- Android and iOS app identifiers are stored as custom properties
## Security considerations
- The tool requires your Bitwarden master password but never stores it
- Each run requires fresh authentication
- The Docker container is removed after each use
- All credentials are handled securely in memory
- The KeePass database is created with your specified password protection
## FAQ
### Why can't I keep my session open?
For security reasons, the Docker container requires fresh authentication each time. This prevents any accidental credential storage and ensures each export starts from a clean state.
### What if I use a self-hosted Vaultwarden instance?
Set the `BITWARDEN_URL` environment variable to your instance URL before running the container:
```sh
docker run --rm -it -v ./exports:/exports -e BITWARDEN_URL="https://your-instance.com" rogsme/bitwarden-to-keepass
```
### Can I use a key file with my KeePass database?
Yes, you can specify a key file path using the `DATABASE_KEYFILE` environment variable. The key file must be accessible to the container.
