## fastpbkdf2-hs

Haskell bindings to the [fastpbkdf2](https://github.com/ctz/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)

benchmarking sha1/cryptonite

time                 29.61 ms   (29.04 ms .. 30.03 ms)

                     0.999 R²   (0.997 R² .. 1.000 R²)

mean                 29.82 ms   (29.47 ms .. 30.40 ms)

std dev              916.0 μs   (527.1 μs .. 1.579 ms)

benchmarking sha1/pbkdf2

time                 8.032 s    (7.899 s .. 8.248 s)

                     1.000 R²   (1.000 R² .. 1.000 R²)

mean                 7.941 s    (7.911 s .. 7.995 s)

std dev              47.08 ms   (0.0 s .. 48.71 ms)

### Installation

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!
