The Challenge

Sensitive local folders need real cryptographic protection without cloud lock-in or opaque closed tools. Windows users wanted military-grade encryption with a simple UI, auditable open source code, and optional auto-destruction against brute force.

The Solution

Built Encrypt-D as a Windows desktop manager with AES-256-GCM, unique salt/nonce per folder and file, PBKDF2-SHA256 (100k iterations), HIDDEN+SYSTEM folder attributes, responsive UI, and configurable failed-attempt limits (1–10 or unlimited). Screaming Architecture for maintainability; shipped under Excelso Open with MIT license.
