How to Use Text Encrypt / Decrypt (AES)
Protect a message with AES encryption and a password, then share the ciphertext safely; decrypt it back with the same password. Everything runs locally, so your text and password never leave your device.
Open the Text Encrypt / Decrypt (AES) tool →What is Text Encrypt / Decrypt (AES)?
Encrypt or decrypt text with a password using AES — entirely in your browser. It's completely free, needs no sign-up, and runs entirely in your browser — so it's fast and private.
How to use Text Encrypt / Decrypt (AES)
- Open the Text Encrypt / Decrypt (AES) tool.
- Paste or type your input.
- Set any options provided.
- Copy the result. Everything runs in your browser — nothing is uploaded.
Frequently asked questions
How secure is it?
It uses AES with a key derived from your password. Security depends on using a strong, unique password — a weak one can be brute-forced.
Can I recover text if I forget the password?
No. Without the exact password the ciphertext cannot be decrypted, so store the password safely.
Is anything uploaded?
No — encryption and decryption run entirely in your browser. Share the password over a separate secure channel from the ciphertext.
