AES Encryption & Decryption
Encrypt and decrypt text using Advanced Encryption Standard (AES) with customizable key sizes. Your data is processed locally and never leaves your browser.
AES Encryption Tool
Secure your text with industry-standard AES encryption
Keep your secret key safe. You will need the same key to decrypt the data. Never share your key with untrusted parties.
About AES Encryption
What is AES?
The Advanced Encryption Standard (AES) is a symmetric encryption algorithm established by the U.S. National Institute of Standards and Technology (NIST) in 2001. It's widely used worldwide and is considered one of the most secure encryption methods available.
Key Sizes
- 128-bit: Fast and secure for most applications
- 192-bit: Enhanced security with moderate performance
- 256-bit: Maximum security for highly sensitive data
Security Notes
- All encryption happens in your browser - no data is sent to any server
- Use strong, random keys for maximum security
- Store your encryption keys safely and separately from encrypted data
- For production use, consider using proper key management systems
