Changelog

• 0.2.1 (2026-01-11)

  • Adds a basic quickcheck test suite for asserting memory safety of library functions on random inputs.

• 0.2.0 (2026-01-10)

  • The HMAC functions now produce a value of type MAC, which is a newtype over a ByteString. The 'Eq' instance for MAC compares values in constant time.

• 0.1.5 (2026-01-08)

  • We now check if the ARM cryptographic extensions are available, and, if so, use them to calculate hashes. If they're unavailable we simply use the pure implementation as a fallback. This yields about a 5x performance boost for 'hash' and 3.5x boost for 'hmac' (again, when available).

  • Allocation for both the 'hash' and 'hmac' functions has been reduced dramatically, mostly by optimising the padding internals, and is now constant with respect to input.

• 0.1.4 (2025-12-28)

  • Adds an 'llvm' build flag and tests with GHC 9.10.3.

• 0.1.3 (2025-01-21)

  • Improves padding handling for the strict bytestring case, yielding performance increases for both 'hash' and 'hmac'.

• 0.1.2 (2025-01-07)

  • Makes a minor optimisation to bytestring handling.

• 0.1.1 (2024-10-13)

  • Adds an INLINE pragma to an internal step function.
  • 'hmac' no longer calls 'hmac_lazy', which has no practical effect other than to clean up profiling reports generated by GHC.

• 0.1.0 (2024-10-07)

  • Initial release.
