@bkchr @tarcieri compared to 0.11.6, the 0.13.0 noticeably improved the perfs, especially for signing operation.

Just to recap.

  • Currently we are using secp256k1 a rust wrapper around a C lib.
  • Not so long ago we were using libsecp256k1 a pure rust implementation.
  • We would like to switch to k256 pure rust implementation as soon as the perfs are fairly close to secp256k1.

Some numbers from criterion benches (https://github.com/davxy/crypto-benches/tree/main/ecdsa)

Signing

* rust-crypto (0.11.6)    [74.929 µs 74.966 µs 75.011 µs]
* rust-crypto (0.13.0)    [41.314 µs 41.320 µs 41.329 µs]
* secp256k1               [27.813 µs 27.829 µs 27.846 µs] 
* libsecp256k1            [95.844 µs 95.853 µs 95.864 µs]

Verification

* rust-crypto (0.11.6)   [99.389 µs 99.421 µs 99.459 µs]
* rust-crypto (0.13.0)   [88.997 µs 89.014 µs 89.032 µs]    
* secp256k1              [31.669 µs 31.697 µs 31.747 µs]
* libsecp256k1           [137.86 µs 137.93 µs 137.99 µs]

Conclusions

As can be seen secp256k1 is still the faster but the gap is not so huge, especially with respect to signing operation.

It would be awesome if we could squeeze the perfs a bit more wrt verification the IMO we can start using k256 all over the place

@davxy we do have plans to improve verification in the next release. Several aspects of verification still operate in constant-time (which is a reasonable place to start when reusing code for both signing and verification).

In v0.13 we started using variable-time inversions for verification which slightly improved performance. In the next release we'd like to move to the generic implementation of wNAF provided by the group crate (already a dependency). There's some initial work here:

https://github.com/RustCrypto/elliptic-curves/pull/708/files

Unfortunately we need some upstream changes to the group crate first:

zkcrypto/group#46

The pure rust versions have the added advantage that they compile.
