Haskell bindings to the fastpbkdf2 library. This is currently (Dec 2016) the
fastest Haskell library for computing the pbkdf2
, outperforming competitors by several order of magnitude (unsuprisingly,
as it hooks into some C code!):
benchmarking sha1/fastpbkdf2
time 4.948 ms (4.850 ms .. 5.040 ms)
0.998 R² (0.997 R² .. 0.999 R²)
mean 4.767 ms (4.707 ms .. 4.825 ms)
std dev 186.5 μs (152.3 μs .. 244.2 μs)
variance introduced by outliers: 20% (moderately inflated)

This library depends from OpenSSL
. I have tried to make this self-contained, but the
crypto layer of OpenSSL (or BoringSSL) requires some fine-tuned ASM code generated during
the build process. Porting everything over in a customised Build.hs
would have been too
much pain, but PR are super welcome!
