# Encrypt

The *Encrypt* action node allows you to hash, encode or encrypt any variable(s) before sending the variable to an external API.

{% hint style="success" %}
The *Encrypt* node only supports encryption for **plain text**.

You can choose from the following encryption methods:

* *Hash*: MD2, MD5, SHA-1, SHA-256, SHA-384 or SHA-512 algorithms.&#x20;
* *Encrypt*: OpenPGP algorithm.&#x20;
* *Encode*: Base64 or Hex algorithms.&#x20;

{% hint style="info" %}
This node is typically used before an [*API Integration*](/flow/action-nodes/action-nodes-api-integration.md) node to either hash, encrypt or encode a variable that is passed in that HTTP call.
{% endhint %}
