Release 0.14.0 by str4d · Pull Request #63 · zkcrypto/group

str4d · 2025-04-16T12:23:38Z

This is a feature branch; PR is open to track the overall 0.14.0 changes.

Adds a provided method to the `Group` trait for performing multiplication by the generator. The use case is overriding this method in the event that precomputed scalar multiplication tables are available, which may be conditional depending on crate features like `alloc` or feature-gated static precomputed tables.

Raise MSRV to 1.63

Bump to rust-random 0.9

Relax Sized requirements on the rng

Provide a `Group::try_from_rng`

Add `Group::mul_by_generator`

Preview 0.14.0-pre.0

Hey @str4d,

Do we have a target date for this to be merged or is it a long term PR that is not intended to be merged right away?

#70 updates rand_core to v0.10 which has been a big blocker

NOTE: depends on zkcrypto/ff#149 Release notes for `rand_core` v0.10.0: https://github.com/rust-random/rand_core/releases/tag/v0.10.0

This unifies the methods previously exposed by the `PrimeCurveAffine` and `CofactorCurveAffine` traits. The prime-order and cofactor traits are now all marker traits, and their affine-specific traits are automatically derived.

Introduce `CurveAffine` trait

Bump `rand_core` to v0.10; MSRV 1.85

Matches the naming adopted in zkcrypto/rfcs#1.

ACK modulo commits I authored.

It'd be good if some of the items from #80 could be addressed, namely #75 and #78

The release of ff v0.14.0 would suggest the boat has already sailed on zkcrypto/rfcs#3

TalDerei

some minor nits.

The release of ff v0.14.0 would suggest the boat has already sailed on zkcrypto/rfcs#3

from that tracking issue, #75 seems like an idiomatic target, will optimistically review #82 (purely additive, backwards compat without ff / trait bound / dep changes). for #78, if the proposed endianness handling lived in group (cc @str4d), it’d require an RFC (new trait + wNAF bounds changes) and don’t think we should block release on that.

ebfull · 2026-05-30T22:46:01Z

Happy to publish 0.14.1 with #82, if it's truly additive. (Haven't had a chance to look.)

tarcieri · 2026-05-31T14:17:43Z

#82 is additive, yes.

It seems fixing #78 is both breaking and needs an RFC, though.

tarcieri · 2026-05-31T14:50:58Z

Also note that while I can take a shot at an RFC I'm still not entirely clear what API would be acceptable.

Should we add a method to e.g. WnafGroup, or should it be a new trait? Does it need an associated type for the bits? What do the bounds on that type look like?

(I think these concerns would be more ergonomic to handle in ff, though there is already a trait for bit-level access based on bitvec, which I would prefer not to use)

ebfull · 2026-06-01T21:36:22Z

Published 0.14.0 on crates.io.
