Is it safe to use this online?

Yes, because we use the Web Crypto API ensuring that your text and keys never leave your browser. However, for highly sensitive government-secret data, always use offline tools.

If I lose my key, can I recover the text?

No. AES is designed to be impossible to crack without the key. If you lose the passphrase, the data is lost forever.

Encryption Tool

Encrypt and decrypt text securely using AES (Advanced Encryption Standard). Generate secure keys and keep your messages private. All processing happens in your browser.

Algorithm

Password (Key)

Note: Messages encrypted with this password/algorithm can only be decrypted with the exact same combination.

Message to Encrypt

Security Notice: All encryption happens locally in your browser using standard crypto libraries (CryptoJS for symmetric, RSA-OAEP for asymmetric). No data is ever sent to our servers. Large files (5MB+) may freeze browser during processing.

How AES Encryption Works

AES (Advanced Encryption Standard) is a symmetric encryption algorithm, meaning the same key is used to encrypt and decrypt the data. It is the global standard for securing sensitive data.
