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*](https://guides.clickatell.com/flow/action-nodes/action-nodes-api-integration) node to either hash, encrypt or encode a variable that is passed in that HTTP call.
