Text Encryptor
Encrypt a message with AES-256 into a safe-to-share text block.
How to use
- Type or paste the secret text.
- Set a strong passphrase.
- Copy the encrypted block and share it - send the passphrase by a different channel.
Frequently asked questions
Is it safe to email the encrypted block?
Yes - without the passphrase it's indistinguishable from random data. Just never send the passphrase in the same channel.
Does the text leave my device?
No. Encryption happens in your browser with Web Crypto; nothing is transmitted or stored.
