[WineHQ Bugzilla]

--- Comment #2 from parhom  ---
I managed to get the plugin's request when run in Windows, it has the same
structure as when it is run in Wine:

{ 
    "acceptableVersionIDs": "100642, 100640, 100641, 100643, 100644, 100645,
100646, 100647, 100648",
    "versionID": "100641",
    "product": "Melodyne",
    "version": "5.1.0",
    "buildNumber": "016",
    "hostName": "DESKTOP-IAO2WGF",
    "language": "en",
    "hostID":
"Y00_0000000000000002-C0C_E930BA58D7561F35-Z0C_10.0.00000000000-40C_DDD91D29DFB80CB9-355_761D92BCBC97F24D-214_E0D89C1E0D9183EA-101_3C1E2E6A74CCFF52-D0C_E930BA58D7561F35",
    "licenseType": "challengeResponse",
    "securitySalt": "6991F731-8A25-42DA-9840-EBF08EB6E245",
    "securityHash": "698e51f4d6f884813b6611ed2a49c9b3a738c2d0"
}

I used Postman and sent this request to the server and got no error, the answer
was:

{
    "checkOpenUrl" =
"https://connect-v1.celemony.com/cgi-bin/WebObjects/LicenseApp.woa/wa/Melodyn...";
    "pingUrl" =
"https://connect-v1.celemony.com/cgi-bin/WebObjects/LicenseApp.woa/wa/Melodyn...";
    "openUrl" =
"https://services.celemony.com/cgi-bin/WebObjects/LicenseApp.woa/wa/Melodyne4...";
    "resultType" = "success";
}

When I put the request, that the plugin generates when run on Wine, I got the
following error message:

{
    "errorCode" = "0";
    "errorMessage" = "general error";
    "resultType" = "error";
}

The parameters that cause the error message when changed for random strings (or
slightly edited) are "hostID", "securitySalt" and "securityHash". And also
"serialNumber", if trying to activate the licensed version, not the trial one.

So it seems, that "securitySalt" and/or "securityHash" are calculated the wrong
way when the plugin is run in Wine.
