AES Encryptor – Text Encryption
Encrypt and decrypt text using AES-256 encryption. Secure your sensitive data with military-grade cryptography.
AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely adopted for securing sensitive data. Our tool uses AES-256-GCM, the most secure variant, which provides both encryption and authentication.
With 256-bit key length, AES-256 offers extremely strong protection against brute-force attacks. The GCM (Galois/Counter Mode) adds integrity verification, ensuring your encrypted data hasn't been tampered with.
All encryption happens locally in your browser using the Web Crypto API - your data never leaves your device, ensuring maximum privacy and security.
Features
- AES-256-GCM military-grade encryption
- 100% client-side - data never leaves your browser
- PBKDF2 key derivation with 100,000 iterations
- Secure random IV generation for each encryption
- Copy encrypted text with one click
How to Use
Enter your text in the input field - this can be any sensitive information you want to protect.
Create a strong secret key (password). Use a mix of letters, numbers, and symbols for best security.
Click 'Encrypt' to transform your text into an encrypted string that can only be decrypted with the same key.
To decrypt, paste the encrypted text, enter the same secret key, and click 'Decrypt' to reveal the original message.
Frequently Asked Questions
Is AES-256 encryption secure?
Yes, AES-256 is considered military-grade encryption and is used by governments and security professionals worldwide. With 2^256 possible key combinations, it's practically impossible to break through brute force.
What happens if I forget my secret key?
Without the exact secret key, the encrypted text cannot be recovered. There is no 'forgot password' option in encryption - this is by design for security. Always store your keys safely.
Is my data sent to any server?
No, all encryption and decryption happens entirely in your browser using the Web Crypto API. Your data, text, and secret keys never leave your device.
