How to encrypt text without a website seeing it
If you want to encrypt a note, a password, or a message, the last thing you want is to type it into a website that sends it to a server. The point of encryption is privacy — so the tool itself shouldn't see your secret.
The problem with online encryptors
Many "encrypt text online" tools send your text (and sometimes your password) to a server to do the work. That defeats the purpose: your plaintext has already left your device before it's protected. Real privacy means the encryption happens where the text is — on your machine.
How in-browser encryption works
Your browser has strong, standardized cryptography built in (the Web Crypto API). A tool can use it to encrypt your text with your password locally — the AES key never leaves the page, and neither does your text. You share only the resulting ciphertext.
How to encrypt privately
Open Toolery's Text Encrypt tool, enter your text and a password, and copy the encrypted output. Everything happens in your browser; nothing you type is sent anywhere. Share the ciphertext, and only someone with the password can read it.
FAQ
Does this send my text to a server?
No. Toolery encrypts text in your browser using the Web Crypto API — your text and password never leave your device.
What encryption is used?
AES-GCM via the browser's built-in Web Crypto, derived from your password — the same standard used to secure the web.
