A type alias of MoneroAddress is provided to abstract away the generic.
To keep the rest of the library sane, MoneroAddress is used everywhere.
If someone wants to use this library with another coin, they *should* be
able to parse a custom address and then recreate it as a Monero address.
While that's annoying to them, better them than any person using this
lib for Monero.
Closes#152.
* Add dkg crate
* Remove F_len and G_len
They're generally no longer used.
* Replace hash_to_vec with a provided method around associated type H: Digest
Part of trying to minimize this trait so it can be moved elsewhere. Vec,
which isn't std, may have been a blocker.
* Encrypt secret shares within the FROST library
Reduces requirements on callers in order to be correct.
* Update usage of Zeroize within FROST
* Inline functions in key_gen
There was no reason to have them separated as they were. sign probably
has the same statement available, yet that isn't the focus right now.
* Add a ciphersuite package which provides hash_to_F
* Set the Ciphersuite version to something valid
* Have ed448 export Scalar/FieldElement/Point at the top level
* Move FROST over to Ciphersuite
* Correct usage of ff in ciphersuite
* Correct documentation handling
* Move Schnorr signatures to their own crate
* Remove unused feature from schnorr
* Fix Schnorr tests
* Split DKG into a separate crate
* Add serialize to Commitments and SecretShare
Helper for buf = vec![]; .write(buf).unwrap(); buf
* Move FROST over to the new dkg crate
* Update Monero lib to latest FROST
* Correct ethereum's usage of features
* Add serialize to GeneratorProof
* Add serialize helper function to FROST
* Rename AddendumSerialize to WriteAddendum
* Update processor
* Slight fix to processor
* Create message types for FROST key gen
Taking in reader borrows absolutely wasn't feasible. Now, proper types
which can be read (and then passed directly, without a mutable borrow)
exist for key_gen. sign coming next.
* Move FROST signing to messages, not Readers/Writers/Vec<u8>
Also takes the nonce handling code and makes a dedicated file for it,
aiming to resolve complex types and make the code more legible by
replacing its previously inlined state.
* clippy
* Update FROST tests
* read_signature_share
* Update the Monero library to the new FROST packages
* Update processor to latest FROST
* Tweaks to terminology and documentation
* Label the version as an alpha
* Add versions to Cargo.tomls
* Update to Zeroize 1.5
* Drop patch versions from monero-serai Cargo.toml
* Add a repository field
* Move generators to OUT_DIR
IIRC, I didn't do this originally as it constantly re-generated them.
Unfortunately, since cargo is complaining about .generators, we have to.
* Remove Timelock::fee_weight
Transaction::fee_weight's has a comment, "Assumes Timelock::None since
this library won't let you create a TX with a timelock". Accordingly,
this is dead code.
Despite being slower and only used for blinding values, its still
extremely performant. 20 is far more standard and will avoid an eye
raise from reviewers.
* Apply Zeroize to nonces used in Bulletproofs
Also makes bit decomposition constant time for a given amount of
outputs.
* Fix nonce reuse for single-signer CLSAG
* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data
* Zeroize private keys and nonces
* Merge prepare_outputs and prepare_transactions
* Ensure CLSAG is constant time
* Pass by borrow where needed, bug fixes
The past few commitments have been one in-progress chunk which I've
broken up as best read.
* Add Zeroize to FROST structs
Still needs to zeroize internally, yet next step. Not quite as
aggressive as Monero, partially due to the limitations of HashMaps,
partially due to less concern about metadata, yet does still delete a
few smaller items of metadata (group key, context string...).
* Remove Zeroize from most Monero multisig structs
These structs largely didn't have private data, just fields with private
data, yet those fields implemented ZeroizeOnDrop making them already
covered. While there is still traces of the transaction left in RAM,
fully purging that was never the intent.
* Use Zeroize within dleq
bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.
* Use Zeroize for random_nonce
It isn't perfect, due to the inability to zeroize the digest, and due to
kp256 requiring a few transformations. It does the best it can though.
Does move the per-curve random_nonce to a provided one, which is allowed
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.
* Use Zeroize on FROST keygen/signing
* Zeroize constant time multiexp.
* Correct when FROST keygen zeroizes
* Move the FROST keys Arc into FrostKeys
Reduces amount of instances in memory.
* Manually implement Debug for FrostCore to not leak the secret share
* Misc bug fixes
* clippy + multiexp test bug fixes
* Correct FROST key gen share summation
It leaked our own share for ourself.
* Fix cross-group DLEq tests
* Initial stab at Bulletproofs+
Does move around the existing Bulletproofs code, does still work as
expected.
* Make the Clsag RCTPrunable type work with BP and BP+
* Initial set of BP+ bug fixes
* Further bug fixes
* Remove RING_LEN as a constant
* Monero v16 TX support
Doesn't implement view tags, nor going back to v14, nor the updated BP
clawback logic.
* Support v14 and v16 at the same time
Currently intended to be done with:
cargo clippy --features "recommended merlin batch serialize experimental
ed25519 ristretto p256 secp256k1 multisig" -- -A clippy::type_complexity
-A dead_code
Increases usage of standardization while expanding dalek_ff_group.
Closes https://github.com/serai-dex/serai/issues/26 by moving
dfg::EdwardsPoint to only be for the prime subgroup.
Updates how change outputs are handled, with a far more logical
construction offering greater flexibility.
prepare_outputs can not longer error. SignaableTransaction::new will.
