keccak

Changed

• Improved performance of software backend on some targets (#129)

Removed

• keccak_backend_soft = "compact" configuration flag and explicit loop
  unrolling (#130)

Fixed

• Warning on softfloat AArch64 targets by not enabling aarch64_sha3
  backend on them (#126)

Fixed

• Warning on softfloat AArch64 targets by not enabling aarch64_sha3 backend on them (#126)

Added

• keccak_backend configuration parameter with aarch64_sha3,
  simd128,
  simd256, simd512, and soft values (#105, #106, #113)
• Keccak struct with a closure-based API for a more efficient access
  to
  supported backends (#113)

Changed

• Edition changed to 2024 and MSRV bumped to 1.85 (#89)
• Bump cpufeatures dependency to v0.3 (#99)
• AArch64 ASM backend is re-implemented using intrinsics (note that it's
  still
  enabled by default on AArch64 targets behind target feature
  auto-detection) (#112)

Removed

• asm, simd, and no_unroll crate features in favor of
  keccak_backend
  and keccak_backend_soft configuration parameters (#105, #106,
  #113)
• f1600 and p1600 functions in favor of the Keccak struct (#113)

Fixed

• Use doc_cfg in place of removed doc_auto_cfg feature (#91)

Added

• keccak_backend configuration parameter with aarch64_sha3, simd128, simd256, simd512, and soft values (#105, #106, #113)

keccak v0.2.0-rc.2 (#111)

keccak v0.2.0-rc.1 (#98)

Releases the following:

• ascon v0.5.0-rc.0
• keccak v0.2.0-rc.0

Backported cherry-pick of: ARMv8 asm! cleanups (#101)

We pass in state.as_mut_ptr() as x0, which was previously marked as
in. However, it's modified in the asm!, e.g.:

sub x0, x0, #192

Note: it's also post-incremented by ld1.1d as state is loaded.

Since it's modified, it needs to be inout. This marks it as such,
using the => _ syntax to discard the result, then it's reset, then
modified as state is written).

Similar mutations were occurring with x1 and x8 as well, which have
been modified accordingly.

Fixed

• ARMv8 asm! invocation had incorrect operand type (#103)

Changed

• Enable ARMv8 ASM backend for p1600 (#68)

Added

• keccak_p fns for [200, 400, 800, 1600] (#55)

Changed

• 2018 edition upgrade (#32)

Added

• ARMv8 SHA3 ASM intrinsics implementation for keccak_f1600 (#23)

Changed

• Implement simd feature with portable_simd instead of deprecated packed_simd (#16)

Added

• Generic keccak-p and keccak-f {200, 400, 800} (#7)
• f1600x{2, 4, 8} (#8)

• Initial release
