Hi all,

I just finished my latest Go Project, which allows Alice and Bob
to send messages or files to each other directly through the Tor
network, as long as their Tor Browser and Tor Exerpert Bundle is
running. Both have created their Tor Hidden Services with Tor
Browser locally and use both Go programs to send/receive messages
or files to each other.

This cuts out third party email servers etc. and the programs focus
on ease of use. :-)

Hope you like the idea!

Addes support for multiple entries (one per line) in the data_file
and comments, starting with #. This allows Alice to send to a group
of people and not only to Bob, in a single session.

Added a 'Note' for users wishing only to use Tor Expert Bundle, without
Tor Browser usage, for the client/server.

Added a 'Usenet-Examples' folder to the repository so that users can use
oc_client.go with Dizum's m2n or Paganini's News Server.

Added a 'minitalk' folder, containing a client and server, so that Alice
and Bob can talk to each other, in realtime.

I reorganized the repository and it consist now of oc_client.go, oc_server.go,
oc_m2n_server.go, oc_paganini_server.go and oc_middleman_server.go.

oc_middleman_server.go is like the name suggest a middleman node, thus
meanining you send with oc_client a message first to the middleman, which
then forwards the message to m2n or paganini. The client sees the path
the message went through. I have not testet yet if this works with multiple
middleman nodes, but I guess it theoretically should.

oc_middleman_server.go needs a special message format containing an
X-OC-To: Header, with the .onion.url, port and password of the
destination server.

In the next couple of days I will set-up a VPS server and test then
oc_email_server.go, so that oc_client.go users can send email to white
listed privacy related email services, or Remailers. In the next step
I will try to implement a mail2onion Gateway, so that oc_client.go
users, with oc_server.go running, can receive anonymous email messages,
as long as their oc_server.go is running (locally). The mail2onion
Gateway will then require 'age'[1] usage so that the destination
address is encrypted and can not bee seen, by for example ,exit
Remailers.

Once this is all done I will try to implement an onion2bitmessage
Gateway. Whish me good luck, so that we have an additional privacy
Network, called Onion Courier, which can not store or log messages
and would allow individuals to run the servers too, whether locally
or on a VPS, without registering a domain. :-)

As sample output from oc_client.go, when sending a message, via middleman,
to dizum's m2n and paganini:

Anonymized the Server output, for more privacy.

Sample output from client, with 3 hops.

$ oc -d data.txt -f out.txt
Using Tor network
Send file...

File sent successfully. Total time: 8 seconds
Server response: File received and sent.
No data is stored or logged by Onion Courier.

Onion Courier Response: File received and sent.
No data is stored or logged by Onion Courier.

Onion Courier Response: File received and sent.
No data is stored or logged by Onion Courier.

Thus when an onlince PC is compromised third
parties do not know what rout it took, because
the first hop (guard node) needs a minicrypt
encrypted message, prior it send to the next hops.

The project is now finnished and you find under Releases
the oc_client for your platform. Example messages file
and public nodes file included.
