The new `FieldElement::from_u256` is sufficient to load an unreduced value. The
caller can perform the square themselves, without us explicitly supporting this
special case.
Updates the monero-oxide version used to one which no longer uses
`FieldElement::from_square` (as their use is why it was added).
If a crate has std set, it should enable std for all dependencies in order to
let them properly select which algorithms to use. Some crates fallback to
slower/worse algorithms on no-std.
Also more aggressively sets default-features = false leading to a *10%*
reduction in the amount of crates coordinator builds.
This will effectively add msrv protections to the entire project as almost
everything grabs from these.
Doesn't add msrv to coins as coins/bitcoin is still frozen.
Doesn't add msrv to services since cargo msrv doesn't play nice with anything
importing the runtime.
* Partial move to ff 0.13
It turns out the newly released k256 0.12 isn't on ff 0.13, preventing further
work at this time.
* Update all crates to work on ff 0.13
The provided curves still need to be expanded to fit the new API.
* Finish adding dalek-ff-group ff 0.13 constants
* Correct FieldElement::product definition
Also stops exporting macros.
* Test most new parts of ff 0.13
* Additionally test ff-group-tests with BLS12-381 and the pasta curves
We only tested curves from RustCrypto. Now we test a curve offered by zk-crypto,
the group behind ff/group, and the pasta curves, which is by Zcash (though
Zcash developers are also behind zk-crypto).
* Finish Ed448
Fully specifies all constants, passes all tests in ff-group-tests, and finishes moving to ff-0.13.
* Add RustCrypto/elliptic-curves to allowed git repos
Needed due to k256/p256 incorrectly defining product.
* Finish writing ff 0.13 tests
* Add additional comments to dalek
* Further comments
* Update ethereum-serai to ff 0.13
This commit greatly expands the usage of black_box/zeroize on bits, as it
originally should have. It is likely overkill, leading to less efficient
code generation, yet does its best to be comprehensive where comprehensiveness
is extremely annoying to achieve.
In the future, this usage of black_box may be desirable to move to its own
crate.
