What is the text encryption tool for?
Sometimes you need to send a piece of sensitive information — an account number, a temporary password, an address, a personal note — through an email or app you don’t fully trust, or keep it in a file on your device. This tool turns the text into an encrypted string that only someone with the password can read.
How to use it
- Choose “Encrypt” and type your message.
- Choose a strong password (ideally a multi-word phrase from the passphrase generator).
- Click “Encrypt text”, then copy the result starting with
WG1:and send it. - Give the recipient the password through another channel (a phone call, for instance), never in the same message.
- The recipient opens the tool, picks “Decrypt”, pastes the text and enters the password.
How strong is it?
- AES-256-GCM: the encryption standard used by banks and governments, with an authentication tag that detects any tampering.
- PBKDF2 with 310,000 iterations: turns the password into a key deliberately slowly, making brute-force guessing very expensive.
- Random salt and IV: encrypting the same text twice gives two different results, so nothing leaks from similarity.
Still, the whole system is only as strong as the password: a short or common one can be guessed whatever the algorithm.
Important notes
- If you forget the password, there is no way to recover the text. We keep no copy.
- It is ideal for messages and notes; for ongoing highly sensitive exchanges, use an end-to-end encrypted messenger.
- Encryption and decryption happen in your browser; neither the text nor the password is ever sent.
