I couldn’t find a local Post-Quantum file encryption tool, so I built my own

说明与用途

作者构建了一个本地零信任加密工具，使用后量子密钥封装机制来保护文件，防止云服务和大型平台的攻击。

问题

Lack of a dedicated local post‑quantum encryption tool that protects files before they reach cloud or third‑party platforms.

结果

The author created a local, zero‑trust encryption tool that protects files before they reach cloud services, addressing concerns about quantum‑resistant security.

工作流

• 1. Install Ombracrypt locally.
• 2. Create a vault and set a master password.
• 3. Add files to the vault; they are encrypted with AES‑256‑GCM or XChaCha20‑Poly and wrapped with a PQC KEM.
• 4. Share encrypted files externally; only the intended recipient can unwrap the key with their PQC key.
• 5. If a duress password is entered, the vault key is permanently destroyed.

证据

I built a zero‑trust, local GUI vault. It combines standard symmetric ciphers (AES‑256‑GCM, XChaCha20‑Poly, etc.) with quantum‑safe KEM algorithms (Cypherpunk Max, X‑wing).
