How to use Text Encryptor

  1. 1Type or paste the message you want to encrypt.
  2. 2Enter a strong password — it stays on your device and cannot be recovered if lost.
  3. 3Click Encrypt to produce a shareable base64 ciphertext string (salt + IV + AES-256-GCM output).
  4. 4Send the ciphertext through one channel and the password through another (e.g. email the text, phone the password).
  5. 5To decrypt: paste the ciphertext, enter the same password, and the original message is restored.

Text Encryptor FAQ

How do I share an encrypted message?
Encrypt your text with a password, then send the ciphertext string through any channel (email, chat, a note). Share the password through a different channel — for example, send the ciphertext by email and the password by phone or in person. Anyone with both can decrypt it here.
Is the encrypted text safe to store or paste anywhere?
Yes — the output is plain base64 text containing a salt, a random IV, and AES-256-GCM ciphertext. It contains no readable part of your message and can be pasted, saved, or printed safely. Only someone with the password (and any copy of this page or the same format) can decrypt it.
Can the password be recovered?
No. The key is derived on your device with PBKDF2-SHA256 and never stored or transmitted. If the password is lost, the text is unrecoverable by design — that is what real encryption means.
