Converting Javascript code to ABAP for calculating HMAC

Sourav1 — Mon, 13 Aug 2018 18:11:48 GMT

Hi,
I am trying to generate a SAS Token from ABAP to connect to Azure Service Bus as described in the following link
https://docs.microsoft.com/en-us/rest/api/eventhub/generate-sas-token#using-the-shared-access-signature-at-http-level

I want to convert the below code to ABAP. Kindly, help out.
The Javascript Code is as follows:

  function createSharedAccessToken(uri, saName, saKey) { 
    if (!uri || !saName || !saKey) { 
            throw"Missing required parameter"; 
        } 
    var encoded = encodeURIComponent(uri); 
    var now = newDate(); 
    var week = 60*60*24*7;
    var ttl = Math.round(now.getTime() / 1000) + week;
    var signature = encoded + '\n' + ttl; 
    var signatureUTF8 = utf8.encode(signature); 
    var hash = crypto.createHmac('sha256', saKey).update(signatureUTF8).digest('base64'); 
    return'SharedAccessSignature sr=' + encoded + '&sig=' +  
        encodeURIComponent(hash) + '&se=' + ttl + '&skn=' + saName; 
}

Guess this will work, https://github.com/Microsoft/ABAP-SDK-for-Azure/blob/7de07cdcf35e8ef60a292d1e6f845bfe3bc39394/src/zadf/zcl_adf_service_servicebus.clas.abap#L20-L68

Its part of the Microsoft ABAP SDK for Azure, which you might want to consider using instead of developing it from scratch
