What are hashing algorithms and their applications?

What are hashing algorithms and how do they work?

Hashing algorithms are functions that convert input data into a fixed-size string of characters, which is typically a hash code. They work by taking an input (or 'message') and returning a unique string of characters that represents that input.

What are some common applications of hashing algorithms?

Hashing algorithms are widely used in various applications such as data integrity verification, password storage, digital signatures, and blockchain technology.

Can you explain how hashing is used in password storage?

Certainly! In password storage, hashing algorithms convert the user's password into a hash. When the user logs in, the entered password is hashed again and compared to the stored hash. This way, the actual password is never stored, enhancing security.

Are there different types of hashing algorithms?

Yes, there are several types of hashing algorithms, including MD5, SHA-1, SHA-256, and SHA-3, each with different levels of security and performance.
