AES Encryption/Decryption

Encrypt and decrypt text using AES-GCM with PBKDF2 key derivation. Runs entirely in your browser.

Use the same password for both encrypting and decrypting.

How to Use AES Encryption/Decryption

  1. 1Enter the text you want to encrypt or the ciphertext to decrypt.
  2. 2Set a strong password for encryption/decryption.
  3. 3Click "Encrypt" to encode or "Decrypt" to decode using AES-GCM.
  4. 4Copy the encrypted ciphertext or decrypted plaintext result.

Frequently Asked Questions

What encryption algorithm is used?▾
AES-GCM (Advanced Encryption Standard in Galois/Counter Mode) with 256-bit keys. Keys are derived from your password using PBKDF2 with 100,000 iterations and SHA-256.
Is my data safe? Does it leave my browser?▾
Yes, your data is safe. All encryption and decryption happens entirely in your browser using the Web Crypto API. No data is ever sent to any server.
What is the output format?▾
The ciphertext is Base64-encoded and includes the salt (16 bytes) and IV (12 bytes) prepended to the encrypted data. This means you only need the password to decrypt.
Can I decrypt data encrypted with other tools?▾
Only if the other tool used the same format: PBKDF2 key derivation (100k iterations, SHA-256), AES-256-GCM, with salt and IV prepended in the same order.
How strong is AES-256-GCM encryption?▾
AES-256-GCM is considered military-grade encryption and is used by governments and financial institutions worldwide. With a strong password, it is practically impossible to crack with current computing technology.
Can I use this tool on my phone?▾
Yes, the AES encryption tool works in any modern mobile browser that supports the Web Crypto API. You can encrypt and decrypt text on any device.
What happens if I forget my password?▾
There is no way to recover encrypted data without the correct password. The encryption is designed to be irreversible without the key. Always store your password in a secure password manager.
