What are the best practices for ensuring security in cryptography?

To ensure security in cryptography, you should use strong algorithms, keep keys secret, and regularly update your systems.

Can you explain what strong algorithms are?

Strong algorithms are those that are widely accepted as secure, such as AES for encryption and SHA-256 for hashing.

How often should I update my cryptographic keys?

It's recommended to update cryptographic keys regularly, at least annually, or immediately if you suspect a compromise.

What should I do if I think my keys have been compromised?

If you suspect a compromise, immediately revoke the keys, generate new ones, and assess the impact of the breach.
