# SHA3

## Description

This operation is used to compute cryptographic hashes using the SHA-3 family of hash functions. SHA-3 offers enhanced security and flexibility compared to its predecessors, including the SHA-2 family.

***

## Data types

These are the input/output expected data types for this operation:

### Input data

`String` - Data you want to process.

### Output data

`String` - SHA-3 hash of the input data.

***

## Parameters

These are the parameters you need to configure to use this operation (mandatory parameters are marked with a <mark style="color:red;">**\***</mark>):

<details>

<summary>Size<mark style="color:red;"><strong>*</strong></mark></summary>

Choose the desired length of bits that the output hash will contain. Enter one of the following:

* `512`
* `384`
* `256`
* `224`

</details>

***

## Example

Suppose you want to get the **SHA3 hashes** a series of strings in your input data:

1. In your Pipeline, open the required [Action](/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **SHA3**.
3. Set **Size** to `512`.
4. Give your **Output field** a name and click **Save**. You'll get the SHA3 hashes of your input strings.

For example:

{% code overflow="wrap" %}

```
Hello World! -> 32400b5e89822de254e8d5d94252c52bdcb27a3562ca593e980364d9848b8041b98eabe16c1a6797484941d2376864a1b0e248b0f7af8b1555a778c336a5bf48
```

{% endcode %}

{% hint style="info" %}
You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
