What are the advantages of hashing in data security?

What are the advantages of hashing in data security?

Hashing provides data integrity, security, and efficient data retrieval. It transforms data into a fixed-size string.

How does hashing improve data integrity?

Hashing ensures that any change in the original data results in a different hash, making it easy to detect alterations.

Can you explain how hashing is used in password storage?

Certainly! Hashing passwords means storing only the hash, not the actual password, enhancing security against breaches.

Are there any disadvantages to using hashing?

Yes, if the hashing algorithm is weak, it can be vulnerable to attacks like collision or brute force.

What are some common hashing algorithms?

Common hashing algorithms include SHA-256, MD5, and bcrypt, each with different strengths and use cases.
