Hi There,

I am trying to write a script that will upload an encrypted file to a remote server. The Content-Type must be multipart/signed and this is what I have but it does not work. Any thoughts on where I am going wrong? (I have taken out the actual remote host for privacy reasons)

POST <remote host> HTTP/1.1
Accept: application/pkcs7-mime; text/plain
connection: keep-alive
Content-Length: 3016
Content-Type: application/pkcs7-mime
Date: Fri, 07 May 2010 21:12:34 GMT
Disposition-Notification-Options: signed-receipt-protocol=required, pkcs7-signature; signed-receipt-micalg=required, sha1
Disposition-notification-to: ver7_admin@123.com
From: ver7_admin@123.com
Host: <remote host>
Message-id: <1273241554.0001.0058@www.123.com>
Mime-Version: 1.0
Receipt-delivery-option: <remote host>

Content-Type: multipart/signed;
protocol="Application/pkcs7-signature";
micalg=sha1;
boundary="--uKwscmW2Ru43XsnrT8xSZ7MockYi2C0N"

--uKwscmW2Ru43XsnrT8xSZ7MockYi2C0N
Content-Type: application/EDI-Consent
Content-Transfer-Encoding: Binary
Content-Disposition: attachment; filename=12484987654321.ent

--uKwscmW2Ru43XsnrT8xSZ7MockYi2C0N
Content-Type: application/pkcs7-signature

<encrypted file>

--uKwscmW2Ru43XsnrT8xSZ7MockYi2C0N--

Any direction is very much appeciated.

"multipart-signed" is for SMTP (email protocol) transfers NOT HTTP

Thanks Chris

However internet based web mail uses HTTP (like hotmail, gmail etc) ... I am under the impression that this is a very common method for secure EDI Transmissions and this is what I am trying to do.

Any help in getting this syntax correct is very much appreciated.

Webmail is a HTTP (Web) interface to a mail server. The messages are received by the mail server over SMTP and stored in a format that the Webmail interface outputs as HTML and the POP3 or MAPI/IMAP interfaces can output to email clients.
