Below is the script. can you please help me where is the mistake. var ACCESS_ID = 'test'; var ACCESS_KEY = 'abc'; var ACCOUNT_NAME = 'cde'; var epoch = (new Date()).getTime(); var id = 2; var resourcePath = '/device/devices'; var data= ''; var requestVars = 'GET' + epoch + resourcePath; var HexUtil = { convertByteArrayToHex : function(byteArray) { var hex = ""; byteArray.forEach(function(byteValue) { hex += HexUtil.convertByteToHex(byteValue); }); return hex; }, convertByteToHex : function(b) { var hexChar = ["0", "1", "2", "3", "4", "5", "6", "7","8", "9", "a", "b", "c", "d", "e", "f"]; return hexChar[(b >> 4) & 0x0f] + hexChar[b & 0x0f]; } }; var key = "lma_Bmz]H_625^5H[EQi9U627pdg}8yy(-56X-hsiL7~e^s)9~56ee+^Mh)i3DKXLODZmNTRhNTUtMDM2MC00ZTY5LTkyNWItZGIwNjZmMDMyZTg5L4kmWbA"; key = encodeURIComponent(key); key = GlideStringUtil.base64Encode(key); var msg = requestVars; msg = encodeURIComponent(msg); var mac = new GlideCertificateEncryption(); signature = mac.generateMac(key, "HmacSHA256", msg); gs.print(signature); // Yes! bp7ym3X//Ft6uuUn1Y/a2y/kLnIZARl2kXNDBl9Y7Uo= var bytes = GlideStringUtil.base64DecodeAsBytes(signature); gs.print(JSON.stringify(bytes)); gs.print(bytes.length); // Yes!
