The skein package

[Tags:bsd3, library, test]

Skein ( is a family of fast secure cryptographic hash functions designed by Niels Ferguson, Stefan Lucks, Bruce Schneier, Doug Whiting, Mihir Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker.

This package uses bindings to the optimized C implementation of Skein. We provide a high-level interface (see module Crypto.Skein) to some of the Skein use cases. We also provide a low-level interface (see module Crypto.Skein.Internal) should you need to use Skein in a different way.

Currently we have support for Skein as cryptographic hash function as Skein as a message authentication code (Skein-MAC). For examples of how to use this package, see Crypto.Skein module documentation.

This package includes Skein v1.3. Versions of this package before 1.0.0 implemented Skein v1.1.

referenceUse the reference implementation instead of the optimized one.DisabledAutomatic
force-endiannessUse a manually selected endian when compiling (see flag 'big-endian').DisabledAutomatic
big-endianWhen manually selecting the endianness, use big-endian (default is little-endian).DisabledAutomatic

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
