Simple python script for decrypting bitwarden vaults exported as password protected json files (not account restricted json files, see https://bitwarden.com/help/encrypted-export/). Supports PBKDF2 and Argon2id. Note that json backups do not contain file attachments, sends, deleted vault items in the trash and shared items.
python bwJsonDecryptor.py filename.json
If you want to create a text file with the content of your vault, add the argument --write.
python bwJsonDecryptor.py filename.json --write
After entering the password that was used to export the vault, the script prints the content of the vault to the terminal and optionally creates a text file called filename.json.txt with the vault content.
Requires packages cryptography and optionally argon2-cffi.
Tested with the export feature directly from vault.bitwarden.com (last tested with version 2024.4.0).
Based on the code by https://github.com/GurpreetKang/BitwardenDecrypt.
