-# Contributing to Rosenpass
-
-## Common operations
-
-### Apply code formatting
-
-Format rust code:
-
-```bash
-cargo fmt
-```
-
-Format rust code in markdown files:
-
-```bash
-./format_rust_code.sh --mode fix
-```
-
-### Spawn a development environment with nix
-
-```bash
-nix develop .#fullEnv
-```
-
-You need to [install this nix package manager](https://wiki.archlinux.org/title/Nix) first.
-
-### Run our test
-
-Make sure to increase the stack size available; some of our cryptography operations require a lot of stack memory.
-
-```bash
-RUST_MIN_STACK=8388608 cargo test --workspace --all-features
-```
-
-### Generate coverage reports
-
-Keep in mind that many of Rosenpass' tests are doctests, so to get an accurate read on our code coverage, you have to include doctests:
-
-```bash
-./coverage_report.sh
-```

-/*
-  This identity hiding process tests whether the rosenpass protocol is able to protect the identity of an initiator or responder.
-  The participants in the test are trusted initiators, trusted responders and compromised initiators and responders.
-  The test consists of two phases. In the first phase all of the participants can communicate with each other using the rosenpass protocol.
-  An attacker observes the first phase and is able to intercept and modify messages and choose participants to communicate with each other
-
-  In the second phase if the anonymity of an initiator is being tested then one of two trusted initiators is chosen.
-  The chosen initiator communicates directly with a trusted responder.
-  If an attacker can determine which initiator was chosen then the anonymity of the initiator has been compromised.
-  Otherwise the protocol has successfully protected the initiators’ identity.
-
-  If the anonymity of a responder is being tested then one of two trusted responders is chosen instead.
-  Then an initiator communicates directly with the chosen responder.
-  If an attacker can determine which responder was chosen then the anonymity of the responder is compromised.
-  Otherwise the protocol successfully protects the identity of a responder.
-
-  The Proverif code treats the public key as synonymous with identity.
-  In the above test when a responder or initiator is chosen what is actually chosen is the public/private key pair to use for communication.
-  Traditionally when a responder or initiator is chosen they would be chosen randomly.
-  The way Proverif makes a "choice" is by simulating multiple processes, one process per choice
-  Then the processes are compared and if an association between a public key and a process can be made the test fails.
-  As the choice is at least as bad as choosing the worst possible option the credibility of the test is maintained.
-  The drawback is that Proverif is only able to tell if the identity can be brute forced but misses any probabilistic associations.
-  As usual Proverif also assumes perfect encryption and in particular assumes encryption cannot be linked to identity.
-
-  One of the tradeoffs made here is that the choice function in Proverif is slow but this is in favour of being able to write more precise tests.
-  Another issue is the choice function does not work with queries so a test needs to be run for each set of assumptions.
-  In this case the test uses secure rng and a fresh secure biscuit key.

-# Additional files
-
-This folder contains additional files that are used in the project.
-
-## `generate_configs.py`
-
-The script is used to generate configuration files for a benchmark setup
-consisting of a device under testing (DUT) and automatic test equipment (ATE),
-basically a strong machine capable of running multiple Rosenpass instances at
-once.
-
-At the top of the script multiple variables can be set to configure the DUT IP
-address and more. Once configured you may run `python3 generate_configs.py` to
-create the configuration files.
-
-A new folder called `output/` is created containing the subfolder `dut/` and
-`ate/`. The former has to be copied on the DUT, ideally reproducible hardware
-like a Raspberry Pi, while the latter is copied to the ATE, i.e. a laptop.
-
-### Running a benchmark
-
-On the ATE a run script is required since multiple instances of `rosenpass` are
-started with different configurations in parallel. The scripts are named after
-the number of instances they start, e.g. `run-50.sh` starts 50 instances.
-
-```shell
-# on the ATE aka laptop
-cd output/ate
-./run-10.sh
-```
-
-On the DUT you start a single Rosenpass instance with the configuration matching
-the ATE number of peers.
-
-```shell
-# on the DUT aka Raspberry Pi
-rosenpass exchange-config configs/dut-10.toml
-```
-
-Use whatever measurement tool you like to monitor the DUT and ATE.
