In a world where sensitive data leaks happen daily, sharing passwords, API keys, or confidential information over email or chat is risky.
We’ve all been there — “Can you send me the database password?” and before you know it, it’s stored permanently in Slack history or someone’s inbox.
That’s the problem Wisp solves.
The Solution: Wisp
Wisp is a secure, one-time secret sharing application.
It allows you to send encrypted secrets via unique links that expire after being viewed or after a set period of time, after which they are permanently deleted.
Key highlights:
- Secrets are encrypted using AES-256-CBC before storage
- Optional password protection
- Links auto-expire after minutes, hours, or days
- Secrets are deleted permanently after first viewing
- No decrypted secret is ever stored server-side
Technical Deep-Dive
Wisp is built with a stack that prioritizes security, developer productivity, and a modern user experience.
Backend
- Laravel 12.21 with PHP 8.4
- Laravel’s AES-256-CBC encryption
- Bcrypt password hashing
- MySQL 8.0+
- PHPUnit for backend tests
Frontend
- Vue 3.5 (Composition API) with TypeScript
- Inertia.js 2.0 for seamless Laravel-Vue integration
- Tailwind CSS 3.4 with shadcn/ui for consistent UI components
- Ziggy for Laravel routes in JavaScript
Hosting
- Deployed on Heroku with HTTPS enforced
Security Implementation
Wisp’s core principle: encrypt sensitive data immediately, destroy it quickly, and never store it in plain text.
How it works:
- Secrets are encrypted with AES-256-CBC before saving to the database.
- If a password is set, it is hashed using Bcrypt and verified before decryption.
- On first view, the secret is permanently deleted.
- If not viewed, it is automatically removed at the set expiration time.
// Laravel encryption example
$encrypted = encrypt($secretContent);
$decrypted = decrypt($encrypted);
Why Inertia.js?
Instead of building a traditional API with a separate frontend, Wisp uses Inertia.js to connect Laravel and Vue directly.
Benefits:
- No need for API controllers or serialization layers
- Laravel handles routing and authentication natively
- SPA experience without managing a separate API stack
Example Inertia route in Laravel:
Route::get('/secrets/create', function () {
return Inertia::render('Secrets/Create');
})->name('secrets.create');
Developer Experience
- Laravel Pint for automatic code formatting
- Nightwatch.js for end-to-end testing of the secret sharing flow
- Full TypeScript support for frontend predictability
- shadcn/ui for accessible and reusable components
