How can hashing be used in data integrity checks?

What is hashing and how does it relate to data integrity?

Hashing is a process that transforms data into a fixed-size string of characters, which is typically a hash code. It ensures data integrity by allowing you to verify that the data has not been altered.

Can you explain how hashing can detect changes in data?

Certainly! When data is hashed, a unique hash value is generated. If the data changes, even slightly, the hash value will change significantly, indicating that the data has been altered.

What are some common hashing algorithms used for data integrity?

Common hashing algorithms include MD5, SHA-1, and SHA-256. Each has different levels of security and performance.

How can I implement hashing in my application for data integrity?

You can implement hashing by using libraries available in your programming language. For example, in Python, you can use the hashlib library to create hash values for your data.
