//! `0.5.x`) will be compatible, but `0.5.x` will not be compatible with `0.6.x`. For versions
|

//! after `1.0.0`, all versions within a "major" version (i.e., `1.0.0`) will be compatible, but

//! Presently, the Keyfork server only supports the following requests:
|
||||
//!
|
||||
//! * Derive Key
|
||||
//!
|
||||
//! ## Extended Private Keys
|
||||
//!
|
||||
//! Keyfork doesn't need to be continuously called once a key has been derived. Once an Extended
|
||||
//! Private Key (often shortened to "XPrv") has been created, further derivations can be performed.
|
||||
//! The tests for this library ensure that all levels of Keyfork derivation beyond the required two
|
||||
//! will be derived similarly between the server and the client.
|
||||
//!
|
||||
//! # Examples
|
||||
//! ```rust
|
||||
//! use std::str::FromStr;
|
||||
//!
|
||||
//! use keyforkd_client::Client;
|
||||
//! use keyfork_derive_util::DerivationPath;
|

|
||||
//! // use k256::SecretKey as PrivateKey;
|
||||
//! // use ed25519_dalek::SigningKey as PrivateKey;
|

# Keyfork Derive: BIP-0032 Key Derivation
|
||||
|
||||
Keyfork offers a [BIP-0032] based hierarchial key derivation system enabling
|
||||
the ability to create keys based on a [BIP-0032] seed, a value between 128 to
|
||||
512 bits. The keys can be made using any algorithm supported by Keyfork Derive.
|
||||
Newtypes can be added to wrap around foreign key types that aren't supported by
|
||||
Keyfork.
|
||||
|
||||
Keys derived with the same parameters, from the same seed, will _always_ return
|
||||
the same value. This makes Keyfork a reliable backend for generating encryption
|
||||
or signature keys, as every key can be recovered using the previously used
|
||||
derivation algorithm. However, this may be seen as a concern, as all an
|
||||
attacker may need to recreate all previously-used seeds would be the original
|
||||
derivation seed. For this reason, it is recommended to use the Keyfork server
|
||||
for derivation from the root seed. The Keyfork server will ensure the root seed
|
||||
and any highest-level keys (such as BIP-44, BIP-85, etc.) keys are not leaked.
|
||||
|
||||
The primary use case of Keyfork Derive will be the creation of Derivation
|
||||
Requests, to be used by Keyforkd Client. In the included example, derivation is
|
||||
performed directly on a master seed. This is how Keyforkd works internally.
|
||||
|
||||
## Example
|
||||
|
||||
```rust
|
||||
use std::str::FromStr;
|
||||
use keyfork_mnemonic_util::Mnemonic;
|
||||
use keyfork_derive_util::{*, request::*};
|
||||
|
||||
fn main() -> Result<(), Box<dyn std::error::Error>> {
|
||||
let mnemonic = Mnemonic::from_str(
|
||||
"enter settle kiwi high shift absorb protect sword talent museum lazy okay"
|
||||
)?;
|
||||
let path = DerivationPath::from_str("m/44'/0'/0'/0/0")?;
|
||||
|
||||
let request = DerivationRequest::new(
|
||||
DerivationAlgorithm::Secp256k1,
|
||||
&path
|
||||
);
|
||||
|
||||
let key1 = request.derive_with_mnemonic(&mnemonic)?;
|
||||
|
||||
let seed = mnemonic.seed(None)?;
|
||||
let key2 = request.derive_with_master_seed(&seed)?;
|
||||
|
||||
assert_eq!(key1, key2);
|
||||
|
||||
Ok(())
|
||||
}

//! # Extended Key Derivation
|
||||
//!
|
||||
//! Oftentimes, a client will want to create multiple keys. Some examples may include deriving
|
||||
//! non-hardened public keys to see how many wallets have been used, deriving multiple OpenPGP
|
||||
//! keys, or generally avoiding key reuse. While Keyforkd locks the root mnemonic and the
|
||||
//! first-level derivation, any second-level derivations acquired from Keyforkd (for example,
|
||||
//! `"m/44'/0'"`) can be used to derive further keys by converting the key to an Extended Public
|
||||
//! Key or Extended Private Key and calling [`ExtendedPublicKey::derive_child`] or
|
||||
//! [`ExtendedPrivateKey::derive_child`].
|
||||
//!
|
||||
//! # Examples
|
||||
//! ```rust
|
||||
//! use std::str::FromStr;
|
||||
//! use keyfork_mnemonic_util::Mnemonic;
|
||||
//! use keyfork_derive_util::{*, request::*};
|
||||
//! use k256::SecretKey;
|
||||

|
||||
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
|
||||
//! # let mnemonic = Mnemonic::from_str(
|
||||
//! # "enter settle kiwi high shift absorb protect sword talent museum lazy okay"
|
||||
//! # )?;

||||
//! let path = DerivationPath::from_str("m/44'/0'/0'/0")?;
|
||||
//! let request = DerivationRequest::new(
|
||||
//! DerivationAlgorithm::Secp256k1, // The algorithm of k256::SecretKey
|
||||
//! &path,
|
||||
//! );
|
||||
//!
|
||||
//! let response = // perform a Keyforkd Client request...
|
||||
//! # request.derive_with_mnemonic(&mnemonic)?;
|
||||
//! let key: ExtendedPrivateKey<SecretKey> = response.try_into()?;

# Keyfork: The Kitchen Sink of Entropy
|
||||
|
||||
**Note:** Keyfork operations are meant to be run on an airgapped machine and
|
||||
Keyfork will error if either any network interfaces are detected or if Keyfork
|
||||
is running on a system with a kernel using an insecure random number generator.
|
||||
|
||||
An all-inclusive crate encapsulating end-user functionality of the Keyfork
|
||||
ecosystem, the Keyfork binary includes all mechanisms that should be exposed to
|
||||
the user when running Keyfork. Information about what operations Keyfork
|
||||
performs are available in detail by running `keyfork help` (each subcommand has
|
||||
thorough documentation) or in the [`docs`] mdBook, but here's a quick overview:
|
||||
|
||||
## Getting Started with Keyfork
|
||||
|
||||
Keyfork offers two options for getting started. For multi-user setups, it is
|
||||
best to look at the detailed documentation for Keyfork Shard. For single-user
|
||||
setups, `keyfork mnemonic generate` will (by default) create a 256-bit mnemonic
|
||||
phrase that can be used to start Keyfork. *Store this phrase*, as it's the only
|
||||
way you'll be able to start Keyfork in the future. It is recommended to use a
|
||||
mnemonic recovery sheet or a printed-steel solution such as the [Billfodl] or
|
||||
[Cryptosteel Capsule].
|
||||
|
||||
```sh
|
||||
keyfork mnemonic generate
|
||||
```
|
||||
|
||||
Once a mnemonic has been generated and stored in a secure manner, Keyfork can
|
||||
be started by "recovering" the server from the mnemonic backup mechanism:
|
||||
|
||||
```sh
|
||||
keyfork recover mnemonic
|
||||
```
|
||||
|
||||
## Deriving Keys
|
||||
|
||||
Keyfork's primary goal is to derive keys. These keys can later be used for
|
||||
things such as signing documents and artifacts or decrypting payloads.
|
||||
Keyfork's first derivation target is OpenPGP, a protocol supporting many
|
||||
cryptographic operations. OpenPGP keys require a User ID, which can be used to
|
||||
identify the owner of the key, either by name or by email. To get an OpenPGP
|
||||
public key (more accurately known as a "cert"), the [`sq`][sq] tool is used to
|
||||
convert a key to a certificate:
|
||||
|
||||
```sh
|
||||
keyfork derive openpgp "John Doe <jdoe@example.com>" | sq key extract-cert
|
||||
```
|
||||
|
||||
All Keyfork derivations are intended to be reproducible. Because of this,
|
||||
Keyfork derived keys can be recreated at any time, only requiring the knowledge
|
||||
of how the key was made.

# Introduction
|
||||
|
||||
Keyfork is a tool to help manage the creation and derivation of binary data
|
||||
using [BIP-0039] mnemonics. A mnemonic is, in simple terms, a way of encoding a
|
||||
large number between 128 and 256 bits, as a list of 12 to 24 words that can be
|
||||
easily stored or memorized. Once a user has a mnemonic, Keyfork utilizes
|
||||
[BIP-0032] to derive cryptographic keys, which can be utilized by a variety of
|
||||
applications.

# Security Considerations
|
||||
|
||||
Keyfork handles data that is considered sensitive. As such, there are a few
|
||||
base considerations we'd like to make about the environment Keyfork is run in.
|
||||
This ensures that the amount of mitigations needed to run Keyfork are reduced.
|
||||
|
||||
## Build Process
|
||||
|
||||
Keyfork should be built using a secure toolchain, such as through Guix or the
|
||||
Distrust Packages system. Using something such as `rustup` means Rust can't
|
||||
properly be verified from source. Ideally, Keyfork should be built by multiple
|
||||
developers and verified between them to ensure the results are deterministic.
|
||||
|
||||
## Hardware
|
||||
|
||||
Keyfork is expected to run on hardware detached from the Internet and from any
|
||||
other computers. This helps ensure the Keyfork seed is never exposed to any
|
||||
online system. Exposing the Keyfork seed may result in a compromise of data
|
||||
derived from Keyfork. The hardware is expected to be stored in a safe location
|
||||
along with the removable storage containing the operating system and (if using
|
||||
Keyfork Shard) the shard file, where adversaries are not able to tamper with
|
||||
the hardware, OS, or shard file.
|
||||
|
||||
## Software
|
||||
|
||||
Keyfork is intended to be one of few programs running on a given system. The
|
||||
ideal system to run Keyfork under is an OS whose only dependencies are Keyfork
|
||||
and Keyfork's runtime dependencies. Because of these restrictions, Keyfork does
|
||||
not necessarily need to include memory-locking or memory-hardening
|
||||
functionality, although such functionality may be included upon further
|
||||
releases.
|
||||
|
||||
## Keys in Memory
|
||||
|
||||
As Keyfork is expected to be the only program running on a given system, it is
|
||||
not expected for Keyfork to defend against malicious software on a system
|
||||
scanning the memory of Keyfork and extracting the keys. As such, at this time,
|
||||
Keyfork does not zero out previously-used memory. Additionally, if such
|
||||
software did exist, because Keyfork is intended to run on hardware detached
|
||||
from the Internet and from any other computers, the risk of practical covert
|
||||
channels is reduced. Tempest and side channel attacks may be mitigated by
|
||||
running Keyfork on hardware located in a Faraday cage.
|
||||
|
||||
## Security of Local Shards
|
||||
|
||||
The threat model of Keyfork in a "local shard" configuration is that an
|
||||
adversary can, without leaking the seed:
|
||||
|
||||
* Compromise `M-1` shard holders or shards
|
||||
|
||||
The threat model of Keyfork in a "local shard" configuration does not include:
|
||||
|
||||
* Compromise of the system running Keyfork
|
||||
|
||||
Keyfork does not provide a mechanism by itself to ensure the operating system
|
||||
or the Keyfork binary has not been tampered with. Users of Keyfork on a shared
|
||||
system should verify the system has not been tampered with before starting
|
||||
Keyfork.
|
||||
|
||||
## Security of Remote Shards
|
||||
|
||||
The threat model of Keyfork in a "remote shard" configuration is that an
|
||||
adversary can, without leaking the seed:
|
||||
|
||||
* Compromise `M-1` shard holders, shard holder devices, or shards
|
||||
* Eavesdrop upon (but not intercept or tamper with) secure communications
|
||||
|
||||
The threat model of Keyfork in a "remote shard" configuration does not include:
|
||||
|
||||
* The compromise of the system initiating the "remote shard" requests.
|
||||
|
||||
Keyfork has a "remote shard" mode, where shards may be transport-encrypted to
|
||||
an ephemeral key and combined on a system run by a user we will call the
|
||||
"administrator". In this design, it is expected that a secure communications
|
||||
channel is established that can be spied upon but can't be tampered with. The
|
||||
administrator can then begin distributing encoded (not encrypted!) public keys
|
||||
to remote shardholders, who then decrypt and re-encrypt the shards to an ECDH
|
||||
AES-256-GCM key. Because the shard is re-encrypted, it can't be intercepted by
|
||||
anyone intercepting the communication. However, it is possible for the
|
||||
administrator to leak either the Keyfork seed or any number of shards if they
|
||||
are the only user operating the system combining the shares.

## Starting Keyfork using remote systems

following command can be run:
|

|

```sh

keyfork recover remote-shard
|
||||
```
|
||||
|
||||
The command will continuously prompt a QR code, followed by 33 words, to be
|
||||
sent to the remote operator. The operator must then perform their operations
|
||||
and send back their own QR code, optionally followed by 72 words. The QR code
|

must be scanned by Keyfork, else the 72 words will be required.
|
||||
This command will continuously prompt 33 words followed by a QR code containing

the words, and read in 72 words until all necessary shards are recovered.
|
||||

### Shard Transport

This command will read in 33 words, prompt for a smartcard PIN, and prompt 72
