What are the best practices for hashing sensitive data?

The best practices for hashing sensitive data include using a strong hashing algorithm, adding a unique salt, and using key stretching techniques.

Can you explain why salting is important?

Salting is important because it adds a unique value to each hash, preventing attackers from using precomputed tables (rainbow tables) to crack the hashes.

What hashing algorithms do you recommend?

I recommend using algorithms like bcrypt, Argon2, or PBKDF2, as they are designed for secure password hashing.

How often should I update my hashing strategy?

You should review and update your hashing strategy regularly, especially when new vulnerabilities are discovered or when your security requirements change.
