Member Function Documentation

bits()

template<typename Generator >

static constexpr std::size_t mckl::Skein< Generator >::bits ( )

inlinestatic

The number of bits of internal state.

Definition at line 263 of file skein.hpp.

bytes()

template<typename Generator >

static constexpr std::size_t mckl::Skein< Generator >::bytes ( )

inlinestatic

The number of bytes of internal state.

Definition at line 260 of file skein.hpp.

hash() [1/2]

template<typename Generator >

static void mckl::Skein< Generator >::hash ( const param_type &  M, std::size_t  N, void *  H  )

inlinestatic

Simple hashing.

Parameters

M	The messages
N	The lenght of the hash value in bits
H	The hash value

Definition at line 269 of file skein.hpp.

hash() [2/2]

template<typename Generator >

static void mckl::Skein< Generator >::hash ( std::size_t  n, const param_type *  M, std::size_t  N, void *  H, const param_type &  K = param_type(), int  Yl = 0, int  Yf = 0, int  Ym = 0  )

inlinestatic

Full Skein interface.

Parameters

n	The number of messages
M	The messages
N	The lenght of the hash value in bits
H	The hash value
K	The optional key
Yl	Tree leaf size
Yf	Tree fan-out
Ym	Tree maximum height

K.type() is ignored. No operation will be done if the types of messages are not valid. And runtime assertions will be rasied if assertion is not disabled.

Tree hashing is ignored for now
