Short information about how the file upload will work.

Since XEP-0363 needs protocol changes, Im not able to implement it directly. But if you have your own webspace, CryptMee can upload files using https to this webspace and send the download URL to your contact.

For this to work, you need an upload service running on the remote web server.
Attached you will find a Perl script which I use on my web server. It also provides a HTML frontend for testing the upload functionality.
Please replace all <placeholders> in this file first (some URLs)!

You can of course implement this upload service in any other language. It should include the following header field in http-response: "download_url" which includes the download URL for your contact.

Once configured in CryptMee file upload will be very easy. Select a picture on your phone, wait some seconds and the download URL will be sent to your contact.

I will try to release the next version soon.
