Protect With Password

Mint a single strong password and password-protect every referenced file with it, "accordingly" per file type. Deterministic, non-destructive (originals are never touched), AES-256 or nothing.

Run it

python3 tools/protect_with_password.py FILE [FILE ...] \
    [--password PW] [--length 24] [--out-dir DIR] \
    [--password-file PATH | --no-password-file]

• Pass every file the user referenced as positional arguments.
• By default a strong password is generated (--password overrides to reuse one).
• Protected copies are written alongside each input, or into --out-dir.
• The tool prints a JSON summary on stdout and a password banner on stderr, and (unless --no-password-file) writes the password to a chmod-600 PROTECT-PASSWORD.txt.

How each type is protected

Native in-file Office (MS-OFFCRYPTO "agile") encryption needs LibreOffice or a dedicated encryptor that is not bundled here, so Office files are wrapped in a strong AES-256 archive instead. If no AES-256 tool is available for a file, it is reported as a failure — never downgraded to weak ZipCrypto/RC4 (no false assurance).

After running

Relay the password to the user and remind them to share it OUT-OF-BAND — never in the same channel/email as the protected files — and to delete PROTECT-PASSWORD.txt once handed over. Exit code is 0 only if every file was protected; 1 if any failed (check results[].reason).

Related: `tools/protect_deliverable.py` does the engagement-wide variant (one protected PDF + an AES-256 deliverable zip); this skill protects an arbitrary set of individual files.
