Safe workflow

  1. 1Encrypt the note, copy the JSON, and store it where you need it.
  2. 2Send the password through a different channel if you must share it.
  3. 3Paste the JSON into decrypt mode and enter the same password to recover the text.

Password tips

  • check_circleUse a long passphrase rather than one short word.
  • check_circleDo not share the password and encrypted JSON in the same place.
  • check_circleKeep a separate backup before encrypting important text.

What the JSON contains

  • data_objectsalt: random value used to derive the AES key from your password
  • data_objectiv: random AES-GCM value generated for every encryption
  • data_objectciphertext: encrypted text body
  • data_objectiterations/keyLength: settings needed to rebuild the same key

How to use the AES text encryptor

Enter text and a password, then encrypt to generate JSON with salt, IV, and ciphertext. Later, paste the JSON and the same password into decrypt mode to recover the original text.

Usage notes

  • Password + salt -> PBKDF2-SHA256 -> AES key
  • Plain text + AES-GCM + IV -> ciphertext
  • Decryption needs both the same password and the JSON package.

Frequently asked questions

Can I recover text if I forget the password?expand_more

No. This tool does not store your password, so forgotten passwords cannot be recovered.

Is the JSON safe to share?expand_more

The ciphertext is not readable without the password if the password is strong and shared separately. Still, limit where you share sensitive data.

Will the same text create the same encrypted result?expand_more

No. New salt and IV values are generated every time, so the output changes.
