Hello everyone,

I have a swift setup with tempauth and formpost.

I have correctly setup a "x-account-meta-temp-url-key" and am using it to create a formpost signature but I keep receiving "Invalid Signature" when uploading.

My form:

<form method="POST" enctype="multipart/form-data" action="">
        <input type="hidden" name="redirect" value="">
        <input type="hidden" name="max_file_size" value="1073741824">
        <input type="hidden" name="max_file_count" value="1">
        <input type="hidden" name="expires" value="1481737496161">
        <input type="hidden" name="signature" value="1b4f64fa08d29807736c382838414ad116533e97">
        <input type="file" name="file">

            <input type="submit">


The private key for this is default1481271067936bizzpeek

I cannot figure out if it either is the signature generation that is faulty (I've created my own as I couldn't find an already made example in nodeJS) or if it is something else...

Can anyone point me in the right direction to troubleshoot this?


I've managed to troubleshoot a bit more, I have used the swift-temp-url that comes with object storage to create the signature for my form, I then edited my form using the given values. This would allow me to be sure that the signature was indeed hashed correctly. I kept getting the same error.

I've then tried to set x-account-meta-temp-url-keyinstead of x-container-meta-temp-url-key and it started working. So I'm guessing that it was saying invalid signature because it couldn't find a temp-url-key to use to confirm the signature.

The new question is, is it possible to use a container's temp-url-key to sign formpost requests or just the account's?

The temp url key is actually on the container, not the account.
