File sharing server with upload via HTTP, written in Go.

You may find this software useful if you own a web server and occasionally:

• want to store/share a file online, but can't/don't want to login to your email/file hosting account or ssh to your server (e.g. using a public PC);
• don't want to manually cleanup temporary shared files.

• No-frills web interface.
• Password protected file upload (warning: no encryption; modify the code to use ListenAndServeTLS or see example lighttpd configuration below for a secure configuration).
• Access from a list (public files) or a direct link (private files).
• Limit access by expiration date or number of downloads (optionally deleting the file from the server afterwards).

go-share [-d DIRECTORY] [-p PORT]

Runs on the port PORT (default: 80), stores files in the directory DIRECTORY (defaults to creating a temporary directory).

$ go-share -p 9321
Please enter a password for file upload:
Please repeat the password:
2014/02/10 04:13:57 Starting go-share on port 9321.
Storage in directory /tmp/go-share131365306

To make go-share appear on http://shared.example.com/ add the following to your lighttpd.conf (assuming you used the port number as in the example above):

$HTTP["host"] =~ "^shared\.example\.com$" {
     proxy.server  = ( "" => ( ("host" => "127.0.0.1", "port" => "9321") ) )
}

If you have a SSL certificate make sure to protect your password by using https. Example lighttpd configuration:

$SERVER["socket"] == ":443" {
    ssl.engine                  = "enable" 
    ssl.pemfile                 = "/etc/lighttpd/ssl/example.com.pem" 
}

To delete a file named X, upload anything with the file name X and expiration date set to something in the past.
