Do you think we are missing an alternative of keccak or a related project?
A pure haskell implementation of the keccak family of hashes.
Documentation available on Hackage.
In the example usage below, I encode
ByteStrings in base16 so that they
can be read as standard hex strings.
ghci> import Data.ByteString.Base16 as BS16 ghci> :t keccak256 keccak256 :: BS.ByteString -> BS.ByteString ghci> BS16.encode $ keccak256 "testing" "5f16f4c7f149ac4f9510d9cf8cf384038ad348b3bcdc01915f95de12df9d1b02" ghci> BS16.encode $ keccak256 "" "c5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470"
NIST uses the Secure Hash Algorithm Validation System
to validate the correctness of hash implementations. For all four variants of
SHA3 and Keccak and the two standard variants of SHAKE, the
pass the standard
KATs (Known Answer Tests).
cryptonite's C-based implementation of Keccack256 is currently 21 times faster
than my Haskell.
benchmarked keccak time 768.3 μs (758.7 μs .. 775.7 μs) 0.998 R² (0.995 R² .. 0.999 R²) mean 774.2 μs (767.5 μs .. 784.0 μs) std dev 29.27 μs (23.12 μs .. 36.87 μs) variance introduced by outliers: 19% (moderately inflated) benchmarked cryptonite-keccak time 36.92 μs (35.95 μs .. 38.03 μs) 0.996 R² (0.995 R² .. 0.998 R²) mean 36.27 μs (35.99 μs .. 36.66 μs) std dev 1.147 μs (918.3 ns .. 1.471 μs) variance introduced by outliers: 14% (moderately inflated)
Eventually, I hope the library will have very few dependencies (only base, vector & bytestring, currently) and excellent performance.
