Strong Encryption Shouldn't Require a Subscription
AES-256 is an open, publicly documented, widely audited encryption standard — the same algorithm used to protect classified government information and secure much of the internet's encrypted traffic. Implementing it correctly is a solved problem, not proprietary technology worth locking behind a paywall for something as simple as encrypting a block of text.
What You Get for Free
- No account needed: enter your text and passphrase, and encrypt — nothing to register first.
- Full AES-256 strength: not a weakened "free tier" cipher — the same encryption standard, unrestricted.
- Unlimited use: encrypt and decrypt as many messages as you need, with no daily cap.
- Runs entirely in your browser: no server involved in the actual encryption process.
Who This Is For
Anyone who needs to send sensitive text over a channel they don't fully trust — email, a shared document, a chat platform — and wants a genuine layer of protection beyond that channel's own security. If you're building encryption into an application at scale, you'll want a proper cryptography library integrated into your codebase — but for occasionally encrypting a message or a block of text by hand, a free browser-based tool is exactly the right amount of tooling.
