How do I store encrypted env variables in Altostra ENV?

I have an Altostra project with a Lambda function that listens on SNS topic, and needs to call another service using an API Token. I need to save the API Key as an env variable, how do I keep it encrypted? Could anybody help me with that? Thanks! enter image description here

It is not recommended to store sensitive data in an env variable, because it will be exposed to anyone who can access the Lambda. A better option is to store the API key in a SSM parameter. AWS SSM is a secured storage for sensitive data.

You can add a SSM parameter reference to an Altostra project and use it in the Lambda like so:

  1. Add a parameter to SSM in AWS web console (Type = SecureString).
  2. Add a SSM resource and the parameter name of the API key: enter image description here
  3. Connect the Lambda to the SSM resource: enter image description here
  4. In the Lambda code, import SSM from aws-sdk, and call ssm.getParameter() in order to use the api-key:

import { SSM } from 'aws-sdk';
const ssm = new SSM();

const param = await ssm.getParameter({
          Name: 'api-key',
          WithDecryption: true,
        }).promise();
