About AES Encryption
AES (Advanced Encryption Standard) is a symmetric encryption algorithm supporting 128/192/256-bit key lengths and multiple operation modes
- Longer key length provides higher security but slightly lower performance
- ECB mode is less secure, consider using CBC or other modes
- When using CBC and other modes, IV is required. Use randomly generated IV recommended
- Use the same key, IV and other parameters for encryption and decryption
