# Keyfork v0.2.4
|
|
||||||
|
|
||||||
This release includes a lot of "maintenance" changes, without any changes in
|
|
||||||
end-user functionality.
|
|
||||||
|
|
||||||
### Changes in keyfork:
|
|
||||||
|
|
||||||
The most significant change in this release is the reorganization of some of
|
|
||||||
the subcommands, where they would be better as enum-traits, such as `keyfork
|
|
||||||
derive` and `keyfork wizard`.
|
|
||||||
|
|
||||||
```
|
|
||||||
b254ba7 cleanup post-merge
|
|
||||||
58d3c34 Merge branch 'main' into ryansquared/staging-since-latest
|
|
||||||
35f57fc Merge branch 'ryansquared/keyfork-mnemonic-refactors'
|
|
||||||
a2eb5fd bump dependencies with listed vulnerabilities (not affected)
|
|
||||||
5219c5a keyfork: enum-trait-ify choose-your-own commands
|
|
||||||
b26f296 keyfork-derive-path-data: move all pathcrafting here
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
f5627e5 keyfork-mnemonic-util: impl try_from_slice and from_array
|
|
||||||
02e5b54 keyfork-mnemonic-util::generate_seed: return const size array
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-derive-openpgp:
|
|
||||||
|
|
||||||
```
|
|
||||||
b254ba7 cleanup post-merge
|
|
||||||
35f57fc Merge branch 'ryansquared/keyfork-mnemonic-refactors'
|
|
||||||
a2eb5fd bump dependencies with listed vulnerabilities (not affected)
|
|
||||||
b26f296 keyfork-derive-path-data: move all pathcrafting here
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-derive-path-data:
|
|
||||||
|
|
||||||
This change now centralizes all special Keyfork paths. This means crates should
|
|
||||||
no longer be required to implement their own path parsing logic.
|
|
||||||
|
|
||||||
```
|
|
||||||
b26f296 keyfork-derive-path-data: move all pathcrafting here
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-derive-util:
|
|
||||||
|
|
||||||
```
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-mnemonic:
|
|
||||||
|
|
||||||
`keyfork-mnemonic-util` has finally been renamed to `keyfork-mnemonic`. The
|
|
||||||
method names `as_bytes() => as_slice()`, `to_bytes() => to_vec()`, and
|
|
||||||
`into_bytes() => into_vec()`, and the function names
|
|
||||||
`from_bytes() => try_from_slice()` and
|
|
||||||
`from_nonstandard_bytes() => from_array()`, have been implemented to more
|
|
||||||
closely represent the native types they are representing. Additionally,
|
|
||||||
`Mnemonic::generate_seed()` has been modified to return a constant size array;
|
|
||||||
this is a breaking change, but should have minimal impact.
|
|
||||||
|
|
||||||
```
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
3ee81b6 keyfork-mnemonic-util: impl as_slice to_vec into_vec
|
|
||||||
f5627e5 keyfork-mnemonic-util: impl try_from_slice and from_array
|
|
||||||
02e5b54 keyfork-mnemonic-util::generate_seed: return const size array
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-prompt:
|
|
||||||
|
|
||||||
```
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-shard:
|
|
||||||
|
|
||||||
```
|
|
||||||
58d3c34 Merge branch 'main' into ryansquared/staging-since-latest
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
f5627e5 keyfork-mnemonic-util: impl try_from_slice and from_array
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyforkd:
|
|
||||||
|
|
||||||
```
|
|
||||||
35ab5e6 keyfork-mnemonic-util => keyfork-mnemonic
|
|
||||||
02e5b54 keyfork-mnemonic-util::generate_seed: return const size array
|
|
||||||
536e6da keyforkd{,-client}: lots of documentationings
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyforkd-client:
|
|
||||||
|
|
||||||
```

# Keyfork v0.2.3
|
|
||||||
|
|
||||||
This release includes a bugfix for the wizard where the wizard was too strict
|
|
||||||
about when keys were "alive".
|
|
||||||
|
|
||||||
### Changes in keyfork:
|
|
||||||
|
|
||||||
```
|
|
||||||
dd4354f keyfork: bump keyfork-shard
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-shard:
|
|
||||||
|
|
||||||
```
|
|
||||||
ba64db8 update Cargo.toml and Cargo.lock
|
|
||||||
fa84a2a keyfork-shard: Be less strict about keys
|
|
||||||
```
|
|
||||||
|
|
||||||
# Keyfork v0.2.2
|
|
||||||
|
|
||||||
This release adds a new wizard, intended to be used at DEFCON 32.
|
|
||||||
|
|
||||||
### Changes in keyfork:
|
|
||||||
|
|
||||||
```
|
|
||||||
8d40d26 keyfork: add `bottoms-up` wizard
|
|
||||||
```
|
|
||||||
|
|
||||||
### Changes in keyfork-derive-openpgp:
|
|
||||||
|
|
||||||
This change also includes a minor change, allowing the derivation path for
|
|
||||||
`keyfork-derive-openpg` to derive further than two paths, which was useful in
|
|
||||||
the testing of the wizard.
|
|
||||||
|
|
||||||
```
|
|
||||||
8d40d26 keyfork: add `bottoms-up` wizard
|
|
||||||
```
|
|
||||||
|
|
||||||
# Keyfork v0.2.1
|
|
||||||
|
|
||||||
This release contains an emergency bugfix for Keyfork Shard, which previously
|
|
||||||
would not be able to properly verify the length of remote shard QR codes.
|
|
||||||
|
|
||||||
# Keyfork v0.2.0
|
|
||||||
|
|
||||||
Some of the changes in this release are based on feedback from audits
|
|
||||||
(publications coming soon!). The previous version of Keyfork, in almost every
|
|
||||||
configuration, is safe to use. The most significant change in this version
|
|
||||||
affects Keyfork Shard, which has an incompatible difference between this
|
|
||||||
version and the previous version. Information about shards, such as the length
|
|
||||||
of the shard, could be leaked and discovered by an attacker when using the
|
|
||||||
Remote Shard recovery mechanism.
|
|
||||||
|
|
||||||
An additional change is the requirement of hardened indices on the first two
|
|
||||||
levels of key derivation. This is due to Keyfork potentially leaking private
|
|
||||||
keys when hardened derivation is not used. To be completely honest, I don't
|
|
||||||
entirely understand the math behind it.
|
|
||||||
|
|
||||||
There is no reason to upgrade if Keyfork has been used as-is, as all supported
|
|
||||||
provisioners at this point in time require hardened derivation at all steps.
|
|
||||||
|
|
||||||

# The Shard Protocol
|
|
||||||
|
|
||||||
Keyfork Shard uses a single-handshake protocol to transfer encrypted shards.
|
|
||||||
The initial payload is generated by the program combining the shards, while the
|
|
||||||
response is generated by the program transport-encrypting the shards.
|
|
||||||
|
|
||||||
## Combiner Payload
|
|
||||||
|
|
||||||
The combiner payload consists of a 12-byte nonce and a 32-byte x25519 public
|
|
||||||
key. The payload is then either encoded to hex and displayed as a QR code, and
|
|
||||||
encoded as a mnemonic and printed on-screen.
|
|
||||||
|
|
||||||
```
|
|
||||||
[12-byte nonce | 32-byte public key]
|
|
||||||
```
|
|
||||||
|
|
||||||
The transporter receives the 12-byte nonce and 32-byte x25519 key and generates
|
|
||||||
their own x25519 key. Using HKDF-Sha256 with no salt on the resulting key
|
|
||||||
generates the AES-256-GCM key used to encrypt the now-decrypted shard, along
|
|
||||||
with the received nonce.
|
|
||||||
|
|
||||||
## Transporter Payload
|
|
||||||
|
|
||||||
The transporter payload consists of a 32-byte x25519 public key and a
|
|
||||||
64-byte-padded encrypted "hunk". The hunk contains a version byte, a threshold
|
|
||||||
byte, and the encrypted shard. The last byte of the 64-byte sequence is the
|
|
||||||
total length of the encrypted hunk.
|
|
||||||
|
|
||||||
```
|
|
||||||
Handshake:
|
|
||||||
[32-byte public key | 63-byte-padded encrypted hunk | 1-byte hunk length ]
|
|
||||||
|
|
||||||
Hunk:
|
|
||||||
[1-byte version | 1-byte threshold | variable-length shard ]
|
|
||||||
```
|
|
||||||
|
|
||||||
The combiner receives the 32-byte x25519 key and the 64-byte hunk, and uses the
|
|
||||||
same key derivation scheme as above to generate the decryption key. The
|
|
||||||
threshold byte is used to determine how many shares (in total) are needed.
