## Hash functions: definition, usage, and examples – IONOS

**A**

**hash**value is the output string generated by a

**hash**

**function**. No matter the input, all of the output strings generated by a particular

**hash**

**function**are of the same length. The length is defined by the type of hashing technology used. The output strings are created from a set of authorized characters defined in the

**hash**

**function**.

## What Is a Hash Function in Cryptography? A Beginner’s Guide

**A**

**hash**

**function**

**is**

**a**unique identifier for any given piece of content. It’s also a process that takes plaintext data of any size and converts it into a unique ciphertext of a specific length. The first part of the definition tells you that no two pieces of content will have the same

**hash**digest, and if the content changes, the

**hash**digest …

## What Is Hash Function? What Is It Used For and Why Is It Important?

**A**

**hash**

**function**in general is a mathematical construct, which possesses a few specific qualities. First, it is a one way

**function**. Any data you put in, will be transformed into a result, that cannot be transformed back to regain the original input. Second, the output is of the same length regardless of the length or contents of your input.
