What are the best practices for AES encryption?

What are the best practices for AES encryption?

The best practices for AES encryption include using a strong key size (at least 256 bits), implementing proper key management, and ensuring secure initialization vectors.

How do I manage encryption keys securely?

You should use a dedicated key management system, rotate keys regularly, and ensure keys are stored securely, away from encrypted data.

What is the importance of initialization vectors?

Initialization vectors (IVs) ensure that the same plaintext encrypts to different ciphertexts each time, enhancing security.

Can you explain the difference between AES-128, AES-192, and AES-256?

The difference lies in the key length: AES-128 uses a 128-bit key, AES-192 uses a 192-bit key, and AES-256 uses a 256-bit key, with longer keys providing stronger security.

Are there any common vulnerabilities I should be aware of?

Yes, common vulnerabilities include weak key management, predictable IVs, and side-channel attacks. Always stay updated on security practices.
