Google Apps Script - Making a url request using sha1 and base64 encode

I have to make a url request with Google Apps Script and for that, I need to enncode my login and password using a sha 1 algorithm and a base64 encoding. In the documantation for the request, I have the following php code :

$string = "loginpassword2017-15-04T09:25:00"; $hash = sha1($string, true); $hash = base64_encode($hash);

So in Google Apps Script, i use the following code :

function GetSHA1(input) { var rawHash = Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_1, input); var txtHash = ''; for (j = 0; j <rawHash.length; j++) { var hashVal = rawHash[j]; if (hashVal < 0) hashVal += 256; if (hashVal.toString(16).length == 1) txtHash += "0"; txtHash += hashVal.toString(16); } return txtHash; }

and then the function

Utilities.base64Encode

Finally I make the url request but authentication is unsuccessful. Does someone know how to do a php sha1 and base64encode in Google Apps Script ? Thanks

What do you mean by 'authentication is unsuccessful'? – Kos
It is a url request to connect to a webservice I actually found the problem, the different sha1 I tested on google apps script differ from the one of php (I tested the encryption in php and tested that in google apps script and it worked) – BrtD
Now my problem is to find a google apps script that is identical to the one of php – BrtD

You can pass the Byte[] array returned from the Utilities::computeDigest directly to a Utilities::base64EncodeWebSafe invocation. So you could do something like the following:

function getLoginHash(loginData) {

    return Utilities.base64EncodeWebSafe(Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_1, loginData));

}
