pmarko1711/bitwardenbackup

Simple Docker image to backup bitwarden passwords with.

Usage

Stdout (raw) output

docker run --rm -e BW_USER=bitwardenemail -e BW_PASS=bitwardenpassword -e RAW=1 pmarko1711/bitwardenbackup

File (encrypted) output

docker run --rm -it -e BW_USER=bitwardenemail -e BW_PASS=bitwardenpassword -e OUTFILE=bw.bck -v /path/to/folder/:/output pmarko1711/bitwardenbackup

• Encryption is performed using gpg2 with a symmetric cypher with BW_PASS used as the passphrase unless GPG_PASS is set (in which case the latter is used).

  • decrypt e.g. using gpg2 -d filename (or echo "password" | gpg --batch --passphrase-fd 0 -d /file/to/backup)

• WSL2 - use -v c:/path/to/folder/:/output volume format

• You might want to delete the volume after not to keep the file, especially if contains raw passwords (see docker volume help).
