Bitcoin RPC Through SSH Tunnel

It involves a client sending requests in JSON format to a server. The server in this case, bitcoind executes the required function and sends a serialized JSON object back to the client as a response. Authentication in bitcond is by means of basic HTTP authentication. SSH is a standard for secure remote login and file transfer over untrusted networks.

Because data flows over an SSH connection, it is encrypted in transit. This makes SSH tunneling an obvious choice when sending and receiving sensitive data. Without SSH tunneling or similar encrypted channel sensitive information such as authentication data, addresses and Bitcoin amounts would be sent over a public network in cleartext. An SSH tunnel can be set up to forward traffic sent to a specified port on localhost to a specified port on a remote host.

Forwarding a port from the client machine to the server machine in this way is known as Local Forwarding. You can either pass command-line options when starting bitcoind to enable the RPC interface and control other necessary settings, or you can add configuration data in a config file. The config file approach is probably the most practical, and is the method covered in this article.

When started, bitcoind looks for a configuration file named bitcoin. By default, bitcoind only allows RPC connections from localhost. Example bitcoin. The example shows a config block for the regtest network. To set up access for mainnet, you would provide a similar configuration block for [main].

For example, to send a request using curl :. In this case, the local network IP address of the client machine is The request sends the method listunspent , which is processed by Bitcoin Core and the result returned as a JSON object.

Authentication data user name and password is sent as base 64 encoded plaintext. This example shows the HTTP header packets including the authorization data. These packets were captured on the server hosting bitcoind , but they show how the data is transmitted over the network.

See for yourself by decoding here. Obviously this is a security vulnerability - an eavesdropper can easily determine the user name and password. If the computer hosting bitcoind is set up to communicate with a client machine by means of SSH, it is pretty straightforward to set up an SSH tunnel. Set up SSH local port forwarding on the client machine that will access the bitcoind server - i. To send traffic through the ssh tunnel, you now use the The same data shown above now results in the following packet - approximately, since the data is encrypted and there is no way to tell which bytes constitute the HTTP header:.

It is fairly straightforward to wrap the SSH tunnel and request process in a Python programme, as this basic example shows:. SSH tunneling fixes this by sending all data over an encrypted channel.

Since the video was created, bitcoin core now requires the rpcbind config entry to open up ports. Use rpcbind to specify the public IP of the machine running the wallet. This should be the same IP that you set in your Bitcoin adapter settings.
