AES Text Decryption
What is AES Text Decryption
This tool decrypts messages that were locked with AES-256-GCM and a password. Paste the Base64 ciphertext, enter the password used to encrypt it, and the original text appears. The key is rebuilt from your password with PBKDF2, and every step runs locally in your browser.
How to use
- Paste the encrypted Base64 text into the input field.
- Enter the exact password used to encrypt it.
- Click Decrypt to reveal the original message.
- Copy the plain text once it appears.
When to use it
Got a scrambled block of text and the password that unlocks it? Paste both here and read the original in one click. It pairs with the AES encrypt tool, so whatever you or a friend locked with a password, you open with the same password. Useful for retrieving a stored secret, a shared credential, or a private note without installing any software.
Frequently asked questions
Is the decryption done privately?
Yes. Decryption runs entirely in your browser through the Web Crypto API. Your ciphertext and password are never uploaded or logged.
Why does it say it could not decrypt?
Usually the password is wrong, or the text was changed or truncated. AES-GCM checks integrity, so even one altered character makes decryption fail.
Can I recover the text if I lost the password?
No. AES-256 has no backdoor. Without the exact password, the original text cannot be recovered.
