What it does
The Text Encryptor locks any text with a password using AES-256-GCM, the same authenticated encryption standard used by TLS and full-disk encryption. Paste a message, choose a password, and you get a compact

ciphertext you can store anywhere or send over any channel - email, chat, a ticket. Only someone who knows the password can turn it back into readable text.The key is derived from your password with PBKDF2 (SHA-256, 100,000 iterations, fresh 16-byte

every time), so identical messages never produce identical ciphertext, and dictionary attacks are slowed by design. Everything runs 100% client-side in your browser: neither the text nor the password is ever sent to a server.How to use it
- Pick a mode with the Encrypt / Decrypt toggle (top left).
- Type or paste your text into the input box - plaintext when encrypting,

- Press Encrypt (or Decrypt). The result appears in the output box with a Copy button.
- After encrypting, press Share ciphertext link to copy a URL that carries the ciphertext (never the password).

Wrong password
Paste the same ciphertext with password wrong-key → Decryption failed - wrong password or corrupted ciphertext.
Good to know
- Authenticated: AES-GCM adds a 16-byte authentication tag, so tampered ciphertext is detected and rejected instead of decrypting to garbage.
- Format: the
