A program to send/receive files between two personal computers.

## Usage

We run the `sendfiles` in computer *A* to receive files:

    sendfiles

And in other computer *B* we specify the files to transfer:

    sendfiles file1.zip file2.zip

This will send `file1.zip` and `file2.zip` files from *B* to *A*. The

IP of *A* is located automatically by *B* with a scan of IP addresses

in the local network and the TCP port 8095.

## Usage

    sendfiles [-ip ADDRESS] [-p PORT] [-k PASSWORD] [file1 [file2...]]

* `-ip ADDRESS` connects to the given IP address of the receiver (scan

  IPs automatically otherwise)

* `-p PORT` TCP port to use for the connection (8095 by default)

* `-k PASSWORD` uses a password/key to match computers that use/known

  the same password. This key is not used to encrypt data (yet).

## Warning: Plain data/key

All information will be transferred in plain data over the network

between computers. There is zero encryption.

## Protocol

The client scans IP addresses in the local network, and tries to

connect to each one through the TCP port 8095. When it is connected,

it sends one line:

    key STRING\n

If the key is accepted, the server/receiver will respond with:

    ok\n

and the client can start sending files. In other case the server will respond:

    invalid key\n

and the connection will be terminated.

When the key is accepted, the client sends files following this protocol:

    file FILENAME size INT64 sha1 STRING\n

    BYTES[size]\n

    file FILENAME size INT64 sha1 STRING\n

    BYTES[size]\n

    ...

    done\n
