AES (Advanced Encryption Standard) is a symmetric encryption algorithm adopted by the U.S. government and used worldwide. It replaced DES as the standard encryption algorithm.
Key features:
Block cipher operating on 128-bit blocks
Key sizes: 128, 192, or 256 bits
Highly secure and efficient
Resistant to known cryptographic attacks
Fast implementation in both hardware and software
Why it's widely used:
Strong security with no known practical attacks
Excellent performance
Standardized and well-tested
Available in most cryptographic libraries
Required for many compliance standards
AES is used in everything from HTTPS connections to file encryption and VPNs.
