office-password-toolkit 0.1.0

office-password-toolkit

Detect, extract, bypass, and decrypt every password gate in Microsoft Office and OpenDocument files.

Installation • Quick start • Commands • Gate catalog • Documentation

office-password-toolkit (CLI: opt) triages, extracts, bypasses, and decrypts passwords and protection across 11 Office products and 80+ file extensions. Point it at a file and it walks the recovery ladder automatically — read a cleartext password, flip a protection flag, strip a record, forge a checksum, open with a built-in default, or decrypt with a key you supply. 62 gates cover every protection type in the Microsoft Office and OpenDocument ecosystems. Only when a gate is genuinely encrypted and no shortcut exists does the tool stop and hand you a hashcat-ready hash line.

Features

• 3 CLI commands — opt info (hash to stdout, status/scheme to stderr), opt unlock (try everything), and opt advanced (8 expert subcommands for surgical control)
• Recovery ladder — each gate is assigned the cheapest viable action: DEFAULT > READ > DECODE > BYPASS > STRIP > COLLIDE > CRACK, applied in order so free wins come first
• 62 gates — every password, protection, and permission mechanism across 11 products: document-open encryption, modify/edit restrictions, sheet/workbook/range/revisions protection, section locks, VBA project passwords, advisory CRC passwords, keyless body ciphers, and digital signatures
• Self-describing unified format — --format opt emits four hash families ($office$, $protect$, $odf$, $vba$) that encode algorithm, key size, and all parameters in a single parseable line
• Hashcat integration — --format hashcat (the default) emits hash lines ready for modes 9400, 9500, 9600, 9700, 9800, 25300, 18400, 18600, and 110
• Built-in decryption — ECMA-376 standard and agile, RC4+MD5, RC4-CryptoAPI, XOR obfuscation, ODF 1.1 (Blowfish), ODF 1.2 (AES-256), ODF 1.3 (Argon2id + AES-GCM), and MSISAM (Microsoft Money)
• Default passwords tried automatically — VelvetSweatshop and /01Hannes Ruescher/01 are attempted before any user-supplied password
• Input never modified — every writing command opens the input read-only and produces a new file
• Python API — import office_password_toolkit as opt; opt.detect("file.xlsx") for programmatic access

Supported formats

hashcat modes emitted: 9400 (Office 2003 standard), 9500 / 9600 (Office 2007-2019 agile), 9700 / 9800 (legacy RC4), 25300 (ISO protection), 18400 / 18600 (ODF), 110 (VBA SHA-1).

Example

# triage a file -- gates and hashes to stdout, human-readable status to stderr
opt info budget.xlsx

# try everything: decode, default passwords, decrypt, collide, bypass
opt unlock secret.docx -p 'Passw0rd'

# expert subcommands for surgical control
opt advanced extract secret.docx | hashcat -m 9600 -     # pipe the hash to hashcat
opt advanced extract secret.docx --format opt             # self-describing $office$*sha512*...
opt advanced decode legacy.xls                            # reverse keyless XOR obfuscation
opt advanced collide mailbox.pst                          # mint a CRC-32 collision password
opt advanced bypass budget.xlsx                           # strip all non-encrypting gates
opt advanced decrypt secret.docx -p 'Passw0rd'           # decrypt with a known password

Python API

import office_password_toolkit as opt

# detect container type and encryption status
result = opt.detect("secret.xlsx")
print(result.container, result.encrypted, result.product)

# extract crackable hash lines
hashes = opt.extract_hashes("secret.xlsx")
for h in hashes:
    print(h.value)  # $office$*2013*...

# enumerate gates (protection mechanisms)
handler = opt.handler_for(result.container)
for gate in handler.gates("secret.xlsx"):
    print(gate.display_name, gate.recovery)

# decrypt with a known password
opt.decrypt_file("secret.xlsx", "decrypted.xlsx", password="Passw0rd")

# bypass removable protection (no password needed)
opt.bypass_file("budget.xlsx", "unlocked.xlsx")

Installation

Install from PyPI (recommended):

uv tool install office-password-toolkit    # exposes both `opt` and `office-password-toolkit`

Or with pip:

pip install office-password-toolkit

Or install from source:

git clone https://github.com/StrongWind1/office-password-toolkit.git
cd office-password-toolkit
uv sync

  models.py / constants.py                           Enums, dataclasses, exit codes, magic bytes

    ole.py / ooxml.py / odf.py / ...                 Container-specific gate enumeration + operations

  crypto/                                            Cryptographic primitives and protocol verifiers
    ciphers.py                                       All cipher operations (sole cryptography import)
    hashes.py                                        All hash/KDF operations (sole argon2-cffi import)
    ecma376.py / rc4legacy.py / odf.py / ...         Format-specific KDFs, verifiers, and decryptors

Third-party crypto libraries are imported in exactly two files: ciphers.py (for cryptography) and hashes.py (for argon2-cffi and pure-Python MD4/MD2). All other modules access cipher and hash operations through these abstractions, so a library API change touches one file.
