How to Set Up HMAC SHA256 Authentication

Hi,

 

Could someone please let me know how to create the hash  authentication using Talend components to fetch data from API. Below is the steps to follow.. I am able to decode the key with Base 64 using t Java component.. but stuck with step 2 mentioned below. 

 

    1. Decode the API key’s secret from Base64 to raw bytes. - I am able to do this using tJava component.

    2. Create the hash using HMAC SHA-256 over the canonical request with the decoded API key secret.

    3. Encode the hash with Base64
