AES encryption and decryption tool

1. AES (Advanced Encryption Standard) is a widely used symmetric-key encryption algorithm.

2. AES supports three key lengths: 128-bit, 192-bit, and 256-bit. The longer the key, the higher the encryption strength.

3. AES is considered extremely secure; to date, no effective attack method has been found to break it.

4. The AES algorithm is highly optimized across multiple platforms, so it delivers excellent performance even in resource-constrained environments.
