It's probably going to take a while for upstream to merge the changes so we're importing just the changed package (BDN) and the new package (Gnark) into this repo. That way we avoid forking the entire repo but can still import our changes. Any changes to these pacakges should be submitted as PRs to upstream _first_, then backported to this repo. Includes: - dedis/kyber#546 - dedis/kyber#551 - dedis/kyber#553

There was a problem hiding this comment.
Could you add an equality test for pubkey vs pubhex and priveky vs privhex to make sure the points are still the same?

Given that kilic is deprecated (and caused us some issues recently), I'm opening this PR with BLS-12-381 backend using https://github.com/Consensys/gnark-crypto/
The Gnark's BLS-12-381 code was audited in the past (but there have been changes to it since), and it is actively maintained.
Signing performance on G2 is comparable to kilic, while the signing on G1 and public key aggregation performance is better than both circl and kilic.
