**Making a new Release of Rosenpass — Cooking Recipe**
If you have to change a file, do what it takes to get the change as commit on the main branch, then **start from step 0**.
If any other issue occurs
0. Make sure you are in the root directory of the project
- `cd "$(git rev-parse --show-toplevel)"`
1. Make sure you locally checked out the head of the main branch
- `git stash --include-untracked && git checkout main && git pull`
2. Make sure all tests pass
- `cargo test --workspace --all-features`
3. Make sure the current version in `rosenpass/Cargo.toml` matches that in the [last release on GitHub](https://github.com/rosenpass/rosenpass/releases)
- Only normal releases count, release candidates and draft releases can be ignored
4. Pick the kind of release that you want to make (`major`, `minor`, `patch`, `rc`, ...)
- See `cargo release --help` for more information on the available release types
- Pick `rc` if in doubt
5. Try to release a new version
- `cargo release rc --package rosenpass`
- An issue was reported? Go fix it, start again with step 0!
6. Actually make the release
- `cargo release rc --package rosenpass --execute`
- Tentatively wait for any interactions, such as entering ssh keys etc.
- You may be asked for your ssh key multiple times!
**Frequently Asked Questions (FAQ)**
- You have untracked files, which `cargo release` complains about?
- `git stash --include-untracked`
- You cannot push to crates.io because you are not logged in?
- Follow the steps displayed in [`cargo login`](https://doc.rust-lang.org/cargo/commands/cargo-login.html)
- How is the release page added to [GitHub Releases](https://github.com/rosenpass/rosenpass/releases) itself?
- Our CI Pipeline will create the release, once `cargo release` pushed the new version tag to the repo. The new release should pop up almost immediately in [GitHub Releases](https://github.com/rosenpass/rosenpass/releases) after the [Actions/Release](https://github.com/rosenpass/rosenpass/actions/workflows/release.yaml) pipeline started.
- No new release pops up in the `Release` sidebar element on the [main page](https://github.com/rosenpass/rosenpass)
- Did you push a `rc` release? This view only shows non-draft release, but `rc` releases are considered as draft. See [Releases](https://github.com/rosenpass/rosenpass/releases) page to see all (including draft!) releases.
- The release page was created on GitHub, but there are no assets/artifacts other than the source code tar ball/zip?
- The artifacts are generated and pushed automatically to the release, but this takes some time (a couple of minutes). You can check the respective CI pipeline: [Actions/Release](https://github.com/rosenpass/rosenpass/actions/workflows/release.yaml), which should start immediately after `cargo release` pushed the new release tag to the repo. The release artifacts only are added later to the release, once all jobs in bespoke pipeline finished.
- How are the release artifacts generated, and what are they?
- The release artifacts are built using one Nix derivation per platform, `nix build .#release-package`. It contains both statically linked versions of `rosenpass` itself and OCI container images.

.Sh NAME
.Nm rosenpass
.Nd builds post-quantum-secure VPNs
.Sh SYNOPSIS
.Nm
.Op COMMAND
.Op Ar OPTIONS ...
.Op Ar ARGS ...
.Sh DESCRIPTION
.Nm
performs cryptographic key exchanges that are secure against quantum-computers
and then outputs the keys.
These keys can then be passed to various services, such as wireguard or other
vpn services, as pre-shared-keys to achieve security against attackers with
quantum computers.
.Pp
This is a research project and quantum computers are not thought to become
practical in fewer than ten years.
If you are not specifically tasked with developing post-quantum secure systems,
you probably do not need this tool.
.Ss COMMANDS
.Bl -tag -width Ds
.It Ar gen-keys --secret-key <file-path> --public-key <file-path>
Generate a keypair to use in the exchange command later.
Send the public-key file to your communication partner and keep the private-key
file secret!
.It Ar exchange private-key <file-path> public-key <file-path> [ OPTIONS ] PEERS
Start a process to exchange keys with the specified peers.
You should specify at least one peer.
.Pp
Its
.Ar OPTIONS
are as follows:
.Bl -tag -width Ds
.It Ar listen <ip>[:<port>]
Instructs
.Nm
to listen on the specified interface and port.
By default,
.Nm
will listen on all interfaces and select a random port.
.It Ar verbose
Extra logging.
.El
.El
.Ss PEER
Each
.Ar PEER
is defined as follows:
.Qq peer public-key <file-path> [endpoint <ip>[:<port>]] [preshared-key <file-path>] [outfile <file-path>] [wireguard <dev> <peer> <extra_params>]
.Pp
Providing a
.Ar PEER
instructs
.Nm
to exchange keys with the given peer and write the resulting PSK into the given
output file.
You must either specify the outfile or wireguard output option.
.Pp
The parameters of
.Ar PEER
are as follows:
.Bl -tag -width Ds
.It Ar endpoint <ip>[:<port>]
Specifies the address where the peer can be reached.
This will be automatically updated after the first successful key exchange with
the peer.
If this is unspecified, the peer must initiate the connection.
.It Ar preshared-key <file-path>
You may specify a pre-shared key which will be mixed into the final secret.
.It Ar outfile <file-path>
You may specify a file to write the exchanged keys to.
If this option is specified,
.Nm
will write a notification to standard out every time the key is updated.
.It Ar wireguard <dev> <peer> <extra_params>
This allows you to directly specify a wireguard peer to deploy the
pre-shared-key to.
You may specify extra parameters you would pass to
.Qq wg set
besides the preshared-key parameter which is used by
.Nm .
This makes it possible to add peers entirely from
.Nm .

# 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.

Rosenpass is used to create post-quantum-secure VPNs. Rosenpass computes a shared key, WireGuard (WG) [@wg] uses the shared key to establish a secure connection. Rosenpass can also be used without WireGuard, deriving post-quantum-secure symmetric keys for another application. The Rosenpass protocol builds on “Post-quantum WireGuard” (PQWG) [@pqwg] and improves it by using a cookie mechanism to provide security against state disruption attacks.

ICR5 and ICR6 perform biscuit replay protection using the biscuit number. This is not handled in `load_biscuit()` itself because there is the case that `biscuit_no = biscuit_used` which needs to be dealt with for retransmission handling.
### Denial of Service Mitigation and Cookies
Rosenpass derives its cookie-based DoS mitigation technique for a responder when receiving InitHello messages from Wireguard [@wg].
When the responder is under load, it may choose to not process further InitHello handshake messages, but instead to respond with a cookie reply message (see Figure \ref{img:MessageTypes}).
The sender of the exchange then uses this cookie in order to resend the message and have it accepted the following time by the reciever.
For an initiator, Rosenpass ignores all messages when under load.
#### Cookie Reply Message
The cookie reply message is sent by the responder on receiving an InitHello message when under load. It consists of the `sidi` of the initiator, a random 24-byte bitstring `nonce` and encrypting `cookie_value` into a `cookie_encrypted` reply field which consists of the following:
```pseudorust
cookie_value = lhash("cookie-value", cookie_secret, initiator_host_info)[0..16]
cookie_encrypted = XAEAD(lhash("cookie-key", spkm), nonce, cookie_value, mac_peer)
```
where `cookie_secret` is a secret variable that changes every two minutes to a random value. `initiator_host_info` is used to identify the initiator host, and is implementation-specific for the client. This paramaters used to identify the host must be carefully chosen to ensure there is a unique mapping, especially when using IPv4 and IPv6 addresses to identify the host (such as taking care of IPv6 link-local addresses). `cookie_value` is a truncated 16 byte value from the above hash operation. `mac_peer` is the `mac` field of the peer's handshake message to which message is the reply.
#### Envelope `mac` Field
Similar to `mac.1` in Wireguard handshake messages, the `mac` field of a Rosenpass envelope from a handshake packet sender's point of view consists of the following:
```pseudorust
mac = lhash("mac", spkt, MAC_WIRE_DATA)[0..16]
```
where `MAC_WIRE_DATA` represents all bytes of msg prior to `mac` field in the envelope.
If a client receives an invalid `mac` value for any message, it will discard the message.
#### Envelope cookie field
The initiator, on receiving a CookieReply message, decrypts `cookie_encrypted` and stores the `cookie_value` for the session into `peer[sid].cookie_value` for a limited time (120 seconds). This value is then used to set `cookie` field set for subsequent messages and retransmissions to the responder as follows:
```pseudorust
if (peer.cookie_value.is_none() || seconds_since_update(peer[sid].cookie_value) >= 120) {
cookie.zeroize(); //zeroed out 16 bytes bitstring
}
else {
cookie = lhash("cookie",peer.cookie_value.unwrap(),COOKIE_WIRE_DATA)
}
```
Here, `seconds_since_update(peer.cookie_value)` is the amount of time in seconds ellapsed since last cookie was received, and `COOKIE_WIRE_DATA` are the message contents of all bytes of the retransmitted message prior to the `cookie` field.
The inititator can use an invalid value for the `cookie` value, when the responder is not under load, and the responder must ignore this value.
However, when the responder is under load, it may reject InitHello messages with the invalid `cookie` value, and issue a cookie reply message.
### Conditions to trigger DoS Mechanism
This whitepaper does not mandate any specific mechanism to detect responder contention (also mentioned as the under load condition) that would trigger use of the cookie mechanism.
For the reference implemenation, Rosenpass has derived inspiration from the linux implementation of Wireguard. This implementation suggests that the reciever keep track of the number of messages it is processing at a given time.
On receiving an incoming message, if the length of the message queue to be processed exceeds a threshold `MAX_QUEUED_INCOMING_HANDSHAKES_THRESHOLD`, the client is considered under load and its state is stored as under load. In addition, the timestamp of this instant when the client was last under load is stored. When recieving subsequent messages, if the client is still in an under load state, the client will check if the time ellpased since the client was last under load has exceeded `LAST_UNDER_LOAD_WINDOW` seconds. If this is the case, the client will update its state to normal operation, and process the message in a normal fashion.
Currently, the following constants are derived from the Linux kernel implementation of Wireguard:
```pseudorust
MAX_QUEUED_INCOMING_HANDSHAKES_THRESHOLD = 4096
LAST_UNDER_LOAD_WINDOW = 1 //seconds
```
## Dealing with Packet Loss
The initiator deals with packet loss by storing the messages it sends to the responder and retransmitting them in randomized, exponentially increasing intervals until they get a response. Receiving RespHello terminates retransmission of InitHello. A Data or EmptyData message serves as acknowledgement of receiving InitConf and terminates its retransmission.
The responder does not need to do anything special to handle RespHello retransmission if the RespHello package is lost, the initiator retransmits InitHello and the responder can generate another RespHello package from that. InitConf retransmission needs to be handled specifically in the responder code because accepting an InitConf retransmission would reset the live session including the nonce counter, which would cause nonce reuse. Implementations must detect the case that `biscuit_no = biscuit_used` in ICR5, skip execution of ICR6 and ICR7, and just transmit another EmptyData package to confirm that the initiator can stop transmitting InitConf.
### Interaction with cookie reply system
The cookie reply system does not interfere with the retransmission logic discussed above.
When the initator is under load, it will ignore processing any incoming messages.
When a responder is under load and it receives an InitHello handshake message, the InitHello message will be discarded and a cookie reply message is sent. The initiator, then on the reciept of the cookie reply message, will store a decrypted `cookie_value` to set the `cookie` field to subsequently sent messages. As per the retransmission mechanism above, the initiator will send a retransmitted InitHello message with a valid `cookie` value appended. On receiving the retransmitted handshake message, the responder will validate the `cookie` value and resume with the handshake process.
When the responder is under load and it recieves an InitConf message, the message will be directly processed without checking the validity of the cookie field.

The [rosenpass tool](./src/) is written in Rust and uses liboqs[^liboqs] and libsodium[^libsodium]. The tool establishes a symmetric key and provides it to WireGuard. Since it supplies WireGuard with key through the PSK feature using Rosenpass+WireGuard is cryptographically no less secure than using WireGuard on its own ("hybrid security"). Rosenpass refreshes the symmetric key every two minutes.
As with any application a small risk of critical security issues (such as buffer overflows, remote code execution) exists; the Rosenpass application is written in the Rust programming language which is much less prone to such issues. Rosenpass can also write keys to files instead of supplying them to WireGuard With a bit of scripting the stand alone mode of the implementation can be used to run the application in a Container, VM or on another host. This mode can also be used to integrate tools other than WireGuard with Rosenpass.
The [`rp`](./rp) tool written in Rust makes it easy to create a VPN using WireGuard and Rosenpass.
The [`rp`](./rp) tool written in bash makes it easy to create a VPN using WireGuard and Rosenpass.
`rp` is easy to get started with but has a few drawbacks; it runs as root, demanding access to both WireGuard
and Rosenpass private keys, takes control of the interface and works with exactly one interface. If you do not feel confident about running Rosenpass as root, you should use the stand-alone mode to create a more secure setup using containers, jails, or virtual machines.

// The reason for this is that we need to figure out how to integrate load detection
// and focused polling for one. Mio event-based polling also does not play nice with
// the current function signature and its reentrant design which is focused around receiving UDP socket packages
// for processing by the crypto protocol server.
// Besides that, there are also some parts of the code which intentionally block
// despite available data. This is the correct behavior; e.g. api::mio::Connection blocks
// further reads from its unix socket until the write buffer is flushed. In other words
// the connection handler makes sure that there is a buffer to put the response in while
// before reading further request.
// The potential problem with this behavior is that we end up ignoring instructions from
// epoll() to read from the particular sockets, so epoll will return information about that
// particular blocked file descriptor every call. We have only so many event slots and
// in theory, the event array could fill up entirely with intentionally blocked sockets.
// We need to figure out how to deal with this situation.
// Mio uses uses epoll in level-triggered mode, so we could handle taint-tracking for ignored
// sockets ourselves. The facilities are available in epoll and Mio, but we need to figure out how mio uses those
// facilities and how we can integrate them here.
// This will involve rewriting a lot of IO code and we should probably have integration
// tests before we approach that.
//
// This hybrid approach is not without merit though; the short poll implementation covers
// all our IO sources, so under contention, rosenpass should generally not hit the long
// poll mode below. We keep short polling and calling epoll() in non-blocking mode (timeout
// of zero) until we run out of IO events processed. Then, just before we would perform a
// blocking poll, we go through all available IO sources to see if we missed anything.
