ZMath Local 1.0.0 — Independent preservation

ZMath Local 1.0.0 — independent preservation release

By Shafaet Brady Hussain.

• Standalone file and message encryption workspace: no login, API key, database, company endpoint or main node.
• Browser-local processing, explicit factor handling, local downloads and bounded input sizes.
• The evaluated ZME1 source snapshot is preserved byte-for-byte; core SHA-256 c48b5af56a50a2c75f682d56843fdc9a82da7714cda1ddee602c5620fa5df8d6.
• 17 former QuantumEncryption1 public pages preserved as a clearly labeled historical archive with scripts/forms/APIs removed and source/output hashes recorded.
• Newly released author-owned code uses PolyForm Noncommercial 1.0.0 with the required copyright notice. Existing CC BY papers and earlier grants remain unchanged.

Use it

Open the static app, or download and extract ZMath-Local-v1.0.0.zip. In the extracted directory, run:

python -m http.server 8765 --bind 127.0.0.1

Then open http://127.0.0.1:8765/. Use localhost or HTTPS for Web Crypto. The app uses standard AES-GCM, PBKDF2 and HKDF, not a new base cipher or independently certified quantum protection. There is no password-reset/recovery service. Older server-bound Portable/Exclusive envelopes cannot be recovered without their original server factor and are deliberately not treated as this format.

Verification

All three Node regression suites passed: preserved crypto contracts, external-factor contracts and local UI/no-network preservation checks. The 17-page archive passed link, executable-content and output-hash checks. A synthetic message encrypted and decrypted successfully in desktop Brave. GitHub checks run automatically on source updates. Tests do not constitute an independent cryptographic audit or exhaustive browser compatibility review.
