AES Text Encryption
What is AES Text Encryption
AES text encryption turns any message into unreadable ciphertext that only someone with the right password can open. This tool uses AES-256-GCM, the same standard banks and governments trust, and builds the key from your password with PBKDF2. Everything runs locally in your browser, so your text and password never reach a server.
How to use
- Paste or type the text you want to protect.
- Choose a strong password and enter it in the password field.
- Click Encrypt to generate the Base64 ciphertext.
- Copy the result, then share the password separately through a safe channel.
When to use it
Need to send a note that should not sit as plain text in an email or chat? Paste it here, pick a password like a short passphrase, and you get a Base64 block you can paste anywhere. The recipient drops it into the AES decrypt tool with the same password and reads the original. Handy for sharing an API key, a recovery phrase, or a private message without trusting a third-party service.
Frequently asked questions
Is my text or password sent anywhere?
No. All encryption happens in your browser with the Web Crypto API. Your text and password never leave your device and nothing is stored.
What algorithm does this use?
AES-256 in GCM mode, with a key derived from your password using PBKDF2 (250,000 iterations, SHA-256). A fresh random salt and IV are generated for every message.
How do I decrypt the result?
Open the AES decrypt tool, paste the Base64 output, and enter the same password. There is no backdoor, so a lost password means the text cannot be recovered.
