Use ChaCha20 instead of ChaCha12
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.

Remove Monero torsion-free requirement and make output keys 32 bytes
Maintains the torsion-free requirement in the one place it's used (key 
images).

In the modern day, the output keys are checked to be points, yet in 
older protocol versions they were allowed to be arbitrary bytes.

Closes https://github.com/serai-dex/serai/issues/23 and 
https://github.com/serai-dex/serai/issues/25.

Utilize zeroize (#76)
* 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

BP Verification (#75)
* Use a struct in an enum for Bulletproofs

* verification bp working for just one proof

* add some more assert tests

* Clean BP verification

* Implement batch verification

* Add a debug assertion w_cache isn't 0

It's initially set to 0 and if not updated, this would be broken.

* Correct Monero workflow yaml

* Again try to corrent Monero workflow yaml

* Again

* Finally

* Re-apply weights as required by Bulletproofs

Removing these was insecure and my fault.

Consolidate GitHub CI actions, split out Monero (#71)
* Consolidate GitHub CI actions, split out Monero

build now includes the specified Rust toolchain/components.

Added a test dependencies action which grabs Foundry and Monero.

Split the Monero v14 job into a matrixed job in its own workflow flow. 
It's now only run when Monero has changes.

* Correct Monero unit/integration tests run timing

Additionally tests a feature-less Monero build.

Also removes a pointless Monero file, which already should have been 
removed, causing this workflow to be triggered.

* Correct exclusion and paths

Updates to FROST should re-run the Monero tests to ensure it didn't 
introduce API incompatibilities.

Bulletproofs+ (#70)
* 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

Remove Monero as a dependency
Introduces missing CLSAG checks. The only difference now should be the 
additional rejection of torsioned points, which is relevant to 
https://github.com/serai-dex/serai/issues/25. Considering this is only 
currently used for FROST verification, this should be fine.

Closes https://github.com/serai-dex/serai/issues/19 by making it 
irrelevant.

Increases priority of https://github.com/serai-dex/serai/issues/68, as 
now it's used for the BP generators which are done at first-proof.

Also merges BP's stricter hash_to_point with the library's, since CLSAG 
has the same bound.

Implement Bulletproofs in Rust (#69)
* Initial attempt at Bulletproofs

I don't know why this doesn't work. The generators and hash_cache lines
up without issue. AFAICT, the inner product proof is valid as well, as
are all included formulas.

* Add yinvpow asserts

* Clean code

* Correct bad imports

* Fix the definition of TWO_N

Bulletproofs work now :D

* Tidy up a bit

* fmt + clippy

* Compile a variety of XMR dependencies with optimizations, even under dev

The Rust bulletproof implementation is 8% slower than C right now, under 
release. This is acceptable, even if suboptimal. Under debug, they take 
a quarter of a second to two seconds though, depending on the amount of 
outputs, which justifies this move.

* Remove unnecessary deref in BPs

Remove the Monero build (#64)
* Remove the Monero CMake and make

* Download the Monero daemon instead of building it

* Cache the Monero daemon

Prevents hammering the Monero servers, should reduce CI time.

* Correct YAML

* Add back sodium-dev

* Create an independent job for downloading the Monero daemon

Improves parallelism while decreasing the amount of work re-done if 
build fails. Also increases modularity.

* Correct Monero job definition

* Correct skipping the Monero download on cache hit

Update the DLEq proof for any amount of generators
The two-generator limit wasn't required nor beneficial. This does 
theoretically optimize FROST, yet not for any current constructions. A 
follow up proof which would optimize current constructions has been

Implement a DLEq library
While Serai only needs the simple DLEq which was already present under 
monero, this migrates the implementation of the cross-group DLEq I 
maintain into Serai. This was to have full access to the ecosystem of 
libraries built under Serai while also ensuring support for it.

The cross_group curve, which is extremely experimental, is feature 
flagged off. So is the built in serialization functionality, as this 
should be possible to make nostd once const generics are full featured, 
yet the implemented serialization adds the additional barrier of 
std::io.

Moves decoy selection to being the last step in the multisig process so 
the RPC is only polled to continue valid transactions.

Successfully get processor to send a transaction out
Modifies FROST behavior so group_key has the offset applied regardless 
of if view was called. The unaltered secret_share and 
verification_shares (as they have differing values depending on the 
signing set) are no longer publicly accessible.

Add Ed25519 to FROST and remove expand_xmd for elliptic_curve's
Doesn't fully utilize ec's hash2curve module as k256 Scalar doesn't have 
FromOkm for some reason. The previously present bigint reduction is 
preserved.

Updates ff/group to 0.12.

Premised on https://github.com/cfrg/draft-irtf-cfrg-frost/pull/205 being 
merged, as while this Ed25519 is vector compliant, it's technically not 
spec compliant due to that conflict.

Generalize out the FROST test for signing/signing with an offset
Moves Schnorr signature tests from test_curve to the new test_schnorr, 
which is more a test_frost.

Relevant to https://github.com/serai-dex/serai/issues/9.

Finish implementing FROST v5
Identity check for P256 and H4 was all that was needed.

Use a transcript when generating the per-chain binding for a given set of keys
While it was fine as-is, as it only had one variable length property, 
this is a bit more robust. Also binds the Curve ID, which should declare 
differently even for just different basepoints, and therefore adds two 
variable length properties (justifying the transcript).

Verify being FROST v5 compliant
No functional changes have been made to signing, with solely slight API 
changes being made.

Technically not actually FROST v5 compatible, due to differing on zero 
checks and randomness, yet the vectors do confirm the core algorithm. 
For any valid FROST implementation, this will be interoperable if they 
can successfully communicate. For any devious FROST implementation, this 
will be fingerprintable, yet should still be valid.

Relevant to https://github.com/serai-dex/serai/issues/9 as any curve can 
now specify vectors for itself and be tested against them.

Moves the FROST testing curve from k256 to p256. Does not expose p256 
despite being compliant. It's not at a point I'm happy with it, notably 
regarding hash to curve, and I'm not sure I care to support p256. If it 
has value to the larger FROST ecosystem...

Implement a proper Monero Timelock type
Transaction scanning now returns the timelock to ensure it's 
acknowledged by wallets.
