Hashing Explained in 1 Minute ⚡ | What Is Hashing & How It Works

In this video, you’ll learn everything you need to know about Hashing—all in just one minute. Hashing is a key concept in computer science and cryptography, where data is transformed into a fixed-size string of characters. It plays a vital role in data integrity, password security, and digital signatures.

What is Hashing?
Hashing is the process of converting input data into a fixed-size string of characters, called a hash value. This technique is widely used for ensuring data integrity, enhancing security, and enabling fast data retrieval.

How Hashing Works
A hash function takes the input data and generates a unique hash code of fixed length. The result appears random, but even the smallest change in the input will produce a completely different hash. This property makes hashing highly effective for verification and security.

What is a Hash Function?
A hash function is a mathematical algorithm that maps data of any size to a fixed-size string. It must be fast, deterministic, and ideally produce unique outputs for different inputs. Popular examples include SHA-256 and MD5.

Applications of Hashing
Hashing is used in many areas: verifying data integrity, securely storing passwords, creating digital signatures, and enabling rapid data lookups in hash tables. Its ability to provide secure, efficient access to information makes it indispensable in computer science and cryptography. #hashtag #datastructures #coding
