 If you've ever tried to use the in-built SRP authentication flows in Cognito (USER_SRP_AUTH or CUSTOM_AUTH) using initiateAuth and respondToAuthChallenge, you may have encountered holes in the documentation that don't explain specific fields (SRP_A, TIMESTAMP, PASSWORD_CLAIM_SIGNATURE). You may also notice that there are no SDK functions that will generate values for these fields, leaving you stuck and unable to progress. This helper was created to bridge the missing support for SRP authentication in AWS Cognito, providing functions that will handle the necessary calculations needed to complete the authentication flow
 
-The helper works by providing functions that generate the required hashes for your secret and password, and wrapping your Cogntio request and returning the same request with the required SRP fields
