Simplest form file uploader.

It just saves uploaded file from HTML form to the new file on the disk.
Also it calculates BLAKE2b checksum, replying with it in the answer.

You can upload files with curl:

    curl -F fileupload=@somedata.tar.gpg http://localhost:8086/upload/

    curl -F fileupload=@somedata.tar.gpg -F comment="optional comment" http://localhost:8086/upload/

You can verify integrity locally:

    b2sum -a blake2b somedata.tar.gpg

You can enable mail notification with -notify-to and -notify-from options.

uploader is free software: see the file COPYING for copying conditions.
