I'm creating a Kotlin app the requires as SAS Token creating which needs HMAC authentication.
The Microsoft website includes various code examples but not a Kotlin example:
https://learn.microsoft.com/en-us/rest/api/eventhub/generate-sas-token
Having researched this further the following example looked promising but the post is very old:
Is there any function for creating Hmac256 string in android?
There's a dependency that needs adding, following which is no longer supported in Android Studio, I wrongly assumed replacing compile with implementation would solve the issue:
compile 'org.apache.directory.studio:org.apache.commons.codec:1.8'
So in short I'm struggling a little, I've setup Postman with a Pre request script and this is generating the required key and works, just need to find a way to migrate this to Kotlin.
The key line of code that I would like some assistance on is:
const hash = CryptoJS.HmacSHA256(signature, saKey).toString(CryptoJS.enc.Base64)
The entire script:
function createSharedAccessToken(uri, saName, saKey) {
if (!uri || !saName || !saKey) {
throw "Missing required parameter";
}
var encoded = encodeURIComponent(uri);
var now = new Date();
var week = 60*60*24*7;
var ttl = Math.round(now.getTime() / 1000) + week;
var signature = encoded + '\n' + ttl;
const hash = CryptoJS.HmacSHA256(signature, saKey).toString(CryptoJS.enc.Base64)
return 'SharedAccessSignature sr=' + encoded + '&sig=' +
encodeURIComponent(hash) + '&se=' + ttl + '&skn=' + saName;
}
Thanks for any assistance or links that may help resolve my problem.
