transilienceai 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 (
--passwordoverrides 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-600PROTECT-PASSWORD.txt.
How each type is protected
| File | Protection | Result |
|---|---|---|
.pdf |
Native AES-256 (qpdf → pypdf fallback) | <name>-protected.pdf — recipient is prompted for the password on open |
.docx/.xlsx/.pptx, .doc/.xls/.ppt, images, anything else |
AES-256 7-Zip archive (-mhe=on, filenames encrypted) |
<name>.7z — recipient extracts with the password (7-Zip / Keka / WinRAR) |
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.
