pastebin

This launches a new hidden-service to share some data as the text/plain MIME type via a Twisted Web server. By default, the data to share is read from stdin. You may also use the option --file (-f) to share a single file instead.

To use stealth authentication on your hidden-service, you can pass the --keys (-k) option which specifies how many authentication cookies to create. This will print out the commands you can send (securely!) to the people you want to share with.

If you wish to serve an entire hierarchy of files as a Web site, instead see instructions at txtorcon (would look like twistd web --port "onion:80" --path ~/public_html with txtorcon installed).

A similar alternative is also onionshare for diverse file-types on many OSes. OnionShare also comes with a GUI.

Note

Note that the hidden-service private keys are in a freshly created temporary directory (TMPDIR is honoured) and that you must save them yourself (by copying them somewhere) before you end (e.g with Control-C) the carml pastebin command, which deletes the tempdir (including the new keys).

If you want to see what it will look like to the people you’re sharing the link with, use --dry-run (-d) which starts a local listener only (i.e. doesn’t launch a Tor, nor set up an actual hidden service). This is preferable to actually-launching a service just to test it.

Examples

$ export TMPDIR=/dev/shm
$ echo "hello hidden-serice world" | carml pastebin
25 bytes to share.
Launching Tor: connected.
People using Tor Browser Bundle can find your paste at (once the descriptor uploads):

   http://ok2byooigb4v53be.onion

If you wish to keep the hidden-service keys, they're in (until we shut down):
/dev/shm/tortmp6eHPg4
Awaiting descriptor upload...
Descriptor uploaded; hidden-service should be reachable.

If you used the stealth-authentication version, it might look like this:

$ carml pastebin -f README.rst --keys 5
4573 bytes to share with 5 authenticated clients.

You requested stealth authentication.
Tor has created 5 keys; each key should be given to one person.
They can set one using the "HidServAuth" torrc option, like so:

  HidServAuth ww2ufwkgxb2kag6t.onion ErQPDEHdNNprvWYCA2vTLR
  HidServAuth f5kb64pe3nygyplx.onion HeemYe0TIoOzU/WkjJwP3R
  HidServAuth ywhbfzepvss5hecm.onion 8JcZKcS8YQXMuYBF/G1z8x
  HidServAuth pow2d55j6ezrruib.onion jK6/yXZ2R7xDsf3sm/PyVh
  HidServAuth t7gnlwzw4hjxc45z.onion ezUZBaPmFYSzrGeZXYJfGh

Alternatively, any Twisted endpoint-aware client can be given
the following string as an endpoint:

  tor:ww2ufwkgxb2kag6t.onion:authCookie=ErQPDEHdNNprvWYCA2vTLR
  tor:f5kb64pe3nygyplx.onion:authCookie=HeemYe0TIoOzU/WkjJwP3R
  tor:ywhbfzepvss5hecm.onion:authCookie=8JcZKcS8YQXMuYBF/G1z8x
  tor:pow2d55j6ezrruib.onion:authCookie=jK6/yXZ2R7xDsf3sm/PyVh
  tor:t7gnlwzw4hjxc45z.onion:authCookie=ezUZBaPmFYSzrGeZXYJfGh

For example, using carml:

  carml copybin --onion tor:ww2ufwkgxb2kag6t.onion:authCookie=ErQPDEHdNNprvWYCA2vTLR
  carml copybin --onion tor:f5kb64pe3nygyplx.onion:authCookie=HeemYe0TIoOzU/WkjJwP3R
  carml copybin --onion tor:ywhbfzepvss5hecm.onion:authCookie=8JcZKcS8YQXMuYBF/G1z8x
  carml copybin --onion tor:pow2d55j6ezrruib.onion:authCookie=jK6/yXZ2R7xDsf3sm/PyVh
  carml copybin --onion tor:t7gnlwzw4hjxc45z.onion:authCookie=ezUZBaPmFYSzrGeZXYJfGh
