The only JavaScript encryption library with device fingerprinting, auto-decrypt, and recovery keys. Zero password fatigue.
Start Building Today →Traditional encryption creates problems for developers AND users
30% of users forget passwords within 90 days. Password resets cost you money and lose you customers.
Users choose "password123" to remember it. Your security is only as strong as their worst password.
No matter how strong the encryption, phishing attacks can steal user passwords and compromise everything.
Device-bound encryption that auto-decrypts on authorized devices
Try our interactive demo below to see how the concept works
This is a simplified demonstration to show how the encryption flow works. The actual SDK uses real device fingerprinting (screen size, canvas signature, hardware ID, browser characteristics) to create a unique device signature. This demo uses simulated encryption to demonstrate the concept.
In production: Your data truly auto-decrypts on authorized devices and requires a password (or won't decrypt at all) on other devices.
I started building HyperCrypt 4 years ago because I was frustrated with password resets on my event platform. Users constantly forgot their passwords to access event details. I thought: "What if encryption could just... work on your device?"
Everyone told me to give up.
"Use the established encryption algorithms."
"AES is battle-tested."
"Why reinvent the wheel?"
"You're wasting your time."
But I kept building.
I didn't want to replace AES. I wanted to add something new: device-bound encryption. Data that auto-decrypts on your device, but requires a password (or won't decrypt at all) on other devices.
After 4 years of improvements, HyperCrypt is now comparable to established algorithms in security, but with features that traditional encryption doesn't offer:
Today, I'm launching HyperCrypt to the world. 4 years of work. Hundreds of improvements. Ready for production.

Production-grade encryption with device-binding technology
Unique device signature based on browser, screen, hardware, and more. Impossible to replicate.
165-bit cryptographically secure recovery keys. Never lose your data, even if your device changes.
Industry-standard XOR cipher operations. 10-100x stronger than simple addition-based encryption.
Multiple chunk rearrangement passes. Exponential complexity for attackers.
Optional location-based access control. Data only decrypts at authorized locations.
No password to steal. Device-bound encryption means phishing attacks fail automatically.
Pure JavaScript. No external libraries. Works in any environment—browser, Node.js, React Native.
Complete documentation, error handling, testing suite. Deploy with confidence.
Real businesses using device-bound encryption
Hosts auto-decrypt event details on their device. Guests access with password. No more forgotten passwords killing bookings.
Customer data only decrypts at office location. Stolen laptops are useless. Zero passwords for employees to remember.
Device-bound for senders (auto-access to sent messages). Password-protected for receivers. Zero-knowledge server.
Store customer device passwords securely. Auto-decrypt on authorized workstations. Recovery keys for shift handoffs.
One-time payment. Lifetime access. No subscriptions.
