polyval: detect VPCLMULQDQ at runtime

4

As of #44, `polyval` will compile to VPCLMULQDQ instructions on new enough CPU architectures. We might be able to use a trick similar to https://github.com/RustCrypto/password-hashes/pull/440 where we detect the relevant...

Add backend for 32 bit targets with wide multiplication?

3

Currently `polyval` (and thus crates built on top of it) uses 32-bit soft backend which was written with targets without wide multiplication in mind. However, this code can be quite...

polyval, ghash: use powers of H to process multiple blocks at a time

6

We can compute `h = [H^n, H^(n-1), ..., H]` and then process N blocks at a time. On a 2020 M1, a stride of 8 runs at about 0.17 cycles...

2

According to [this issue](https://github.com/RustCrypto/AEADs/issues/685), bundled ghash should be removed from `belt-dwp` crate. Could you clarify your preferred approach for this? I suggest, we should add generic param for arithmetic, like...
