AES Encrypt / Decrypt
Encrypt and decrypt text with AES-GCM using a password — entirely in your browser.
AES-256-GCM with PBKDF2 (200k iterations). Lose the password and the text is unrecoverable.
How to use the AES Encrypt / Decrypt
-
Enter text and a password.
-
Encrypt to get a Base64 blob.
-
Decrypt it later with the same password.
Encrypt text with AES
AES-GCM is a modern, authenticated encryption standard. This tool derives a key from your password (PBKDF2) and encrypts or decrypts text locally, producing a self-contained Base64 blob that includes the salt and IV. Nothing is transmitted, so only someone with the password can decrypt it.
Key features
- AES-256-GCM authenticated encryption
- Password-based key derivation (PBKDF2)
- Self-contained Base64 output
- Fully local — no servers involved
Frequently asked questions
What happens if I lose the password?
The text cannot be recovered — there's no backdoor or reset. Keep the password safe.
Is this secure?
It uses AES-256-GCM with PBKDF2 key derivation, but for high-stakes secrets use a vetted, audited tool.
Is my text or password uploaded?
No — all encryption happens locally with the Web Crypto API.
