 |:----------:|-------------|
-| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default) archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |

 | `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
 | `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
 | `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
 | `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
 | `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |

-Binary Merkle Tree Hash is a hash function over arbitrary datachunks of limited size
-It is defined as the root hash of the binary merkle tree built over fixed size segments
-of the underlying chunk using any base hash function (e.g keccak 256 SHA3)
-
-It is used as the chunk hash function in swarm which in turn is the basis for the
-128 branching swarm hash http://swarm-guide.readthedocs.io/en/latest/architecture.html#swarm-hash
-
-The BMT is optimal for providing compact inclusion proofs, i.e. prove that a
-segment is a substring of a chunk starting at a particular offset
-The size of the underlying segments is fixed at 32 bytes (called the resolution
-of the BMT hash), the EVM word size to optimize for on-chain BMT verification
-as well as the hash size optimal for inclusion proofs in the merkle tree of the swarm hash.
-
-Two implementations are provided:
-
-* RefHasher is optimized for code simplicity and meant as a reference implementation
-* Hasher is optimized for speed taking advantage of concurrency with minimalistic
-  control structure to coordinate the concurrent routines
-  It implements the ChunkHash interface as well as the go standard hash.Hash interface

+# Setting up Clef
+
+This document describes how Clef can be used in a more secure manner than executing it from your everyday laptop, 
+in order to ensure that the keys remain safe in the event that your computer should get compromised. 
+
+## Qubes OS
+
+
+### Background 
+
+The Qubes operating system is based around virtual machines (qubes), where a set of virtual machines are configured, typically for 
+different purposes such as:
+
+- personal
+   - Your personal email, browsing etc
+- work
+  - Work email etc
+- vault
+  - a VM without network access, where gpg-keys and/or keepass credentials are stored. 
+
+A couple of dedicated virtual machines handle externalities:
+
+- sys-net provides networking to all other (network-enabled) machines
+- sys-firewall handles firewall rules
+- sys-usb handles USB devices, and can map usb-devices to certain qubes.
+
+The goal of this document is to describe how we can set up clef to provide secure transaction
+signing from a `vault` vm, to another networked qube which runs Dapps.
+
+### Setup
+
+There are two ways that this can be achieved: integrated via Qubes or integrated via networking. 
+
+
+#### 1. Qubes Integrated
+
+Qubes provdes a facility for inter-qubes communication via `qrexec`. A qube can request to make a cross-qube RPC request 
+to another qube. The OS then asks the user if the call is permitted. 
+
+![Example](qubes/qrexec-example.png)
+
+A policy-file can be created to allow such interaction. On the `target` domain, a service is invoked which can read the
+`stdin` from the `client` qube. 
+
+This is how [Split GPG](https://www.qubes-os.org/doc/split-gpg/) is implemented. We can set up Clef the same way:
+
+##### Server
+
+![Clef via qrexec](qubes/clef_qubes_qrexec.png)
+
+On the `target` qubes, we need to define the rpc service.
+
+[qubes.Clefsign](qubes/qubes.Clefsign):
+
+```bash
+#!/bin/bash
+
+SIGNER_BIN="/home/user/tools/clef/clef"
+SIGNER_CMD="/home/user/tools/gtksigner/gtkui.py -s $SIGNER_BIN"
+
+# Start clef if not already started
+if [ ! -S /home/user/.clef/clef.ipc ]; then
+	$SIGNER_CMD &
+	sleep 1
+fi
+
+# Should be started by now
+if [ -S /home/user/.clef/clef.ipc ]; then
+    # Post incoming request to HTTP channel
+	curl -H "Content-Type: application/json" -X POST -d @- http://localhost:8550 2>/dev/null
+fi
+
+```
+This RPC service is not complete (see notes about HTTP headers below), but works as a proof-of-concept. 
+It will forward the data received on `stdin` (forwarded by the OS) to Clef's HTTP channel.  
+
+It would have been possible to send data directly to the `/home/user/.clef/.clef.ipc` 
+socket via e.g `nc -U /home/user/.clef/clef.ipc`, but the reason for sending the request 
+data over `HTTP` instead of `IPC` is that we want the ability to forward `HTTP` headers.
+
+To enable the service:
+
+``` bash
+sudo cp qubes.Clefsign /etc/qubes-rpc/
+sudo chmod +x /etc/qubes-rpc/ qubes.Clefsign
+```
+
+This setup uses [gtksigner](https://github.com/holiman/gtksigner), which is a very minimal GTK-based UI that works well 
+with minimal requirements. 
+
+##### Client
+
+
+On the `client` qube, we need to create a listener which will receive the request from the Dapp, and proxy it. 
+
+
+[qubes-client.py](qubes/client/qubes-client.py):
+
+```python
+
+"""
+This implements a dispatcher which listens to localhost:8550, and proxies
+requests via qrexec to the service qubes.EthSign on a target domain
+"""
+
+import http.server
+import socketserver,subprocess
+
+PORT=8550
+TARGET_DOMAIN= 'debian-work'
+
+class Dispatcher(http.server.BaseHTTPRequestHandler):
+    def do_POST(self):
+        post_data = self.rfile.read(int(self.headers['Content-Length']))
+        p = subprocess.Popen(['/usr/bin/qrexec-client-vm',TARGET_DOMAIN,'qubes.Clefsign'],stdin=subprocess.PIPE, stdout=subprocess.PIPE)
+        output = p.communicate(post_data)[0]
+        self.wfile.write(output)
+
+
+with socketserver.TCPServer(("",PORT), Dispatcher) as httpd:
+    print("Serving at port", PORT)
+    httpd.serve_forever()
+
+
+```
+
+#### Testing
+
+To test the flow, if we have set up `debian-work` as the `target`, we can do
+ 
+```bash
+$ cat newaccnt.json 
+{ "id": 0, "jsonrpc": "2.0","method": "account_new","params": []}
+
+$ cat newaccnt.json| qrexec-client-vm debian-work qubes.Clefsign
+```
+
+This should pop up first a dialog to allow the IPC call:
+
+![one](qubes/qubes_newaccount-1.png)
+
+Followed by a GTK-dialog to approve the operation
+
+![two](qubes/qubes_newaccount-2.png)
+
+To test the full flow, we use the client wrapper. Start it on the `client` qube:
+```
+[user@work qubes]$ python3 qubes-client.py 
+```
+
+Make the request over http (`client` qube):
+```
+[user@work clef]$ cat newaccnt.json | curl -X POST -d @- http://localhost:8550
+```
+And it should show the same popups again. 
+
+##### Pros and cons
+
+The benefits of this setup are:
+
+- This is the qubes-os intended model for inter-qube communication,
+- and thus benefits from qubes-os dialogs and policies for user approval
+
+However, it comes with a couple of drawbacks:
+
+- The `qubes-gpg-client` must forward the http request via RPC to the `target` qube. When doing so, the proxy
+  will either drop important headers, or replace them. 
+  - The `Host` header is most likely `localhost` 
+  - The `Origin` header must be forwarded
+  - Information about the remote ip must be added as a `X-Forwarded-For`. However, Clef cannot always trust an `XFF` header, 
+  since malicious clients may lie about `XFF` in order to fool the http server into believing it comes from another address.
+- Even with a policy in place to allow rpc-calls between `caller` and `target`, there will be several popups:
+  - One qubes-specific where the user specifies the `target` vm
+  - One clef-specific to approve the transaction
+  
+
+#### 2. Network integrated
+
+The second way to set up Clef on a qubes system is to allow networking, and have Clef listen to a port which is accessible
+form other qubes. 
+
+![Clef via http](qubes/clef_qubes_http.png)

+## USBArmory
+
+The [USB armory](https://inversepath.com/usbarmory) is an open source hardware design with an 800 Mhz ARM processor. It is a pocket-size
+computer. When inserted into a laptop, it identifies itself as a USB network interface, basically adding another network
+to your computer. Over this new network interface, you can SSH into the device. 
+
+Running Clef off a USB armory means that you can use the armory as a very versatile offline computer, which only
+ever connects to a local network between your computer and the device itself.
+
+Needless to say, the while this model should be fairly secure against remote attacks, an attacker with physical access
+to the USB Armory would trivially be able to extract the contents of the device filesystem.
