Constructor & Destructor Documentation

◆ CSipHasher()

CSipHasher::CSipHasher ( uint64_t  k0,
uint64_t  k1 
)

Construct a SipHash calculator initialized with 128-bit key (k0, k1)

Definition at line 27 of file siphash.cpp.

Member Function Documentation

◆ Finalize()

uint64_t CSipHasher::Finalize ( ) const

Compute the 64-bit SipHash-2-4 of the data written so far.

The object remains untouched.

Definition at line 82 of file siphash.cpp.

Here is the caller graph for this function:

◆ Write() [1/2]

CSipHasher & CSipHasher::Write ( const uint8_t *  data,
size_t  size 
)

Hash arbitrary bytes.

Definition at line 55 of file siphash.cpp.

◆ Write() [2/2]

CSipHasher & CSipHasher::Write ( uint64_t  data)

Hash a 64-bit integer worth of data.

It is treated as if this was the little-endian interpretation of 8 bytes. This function can only be used when a multiple of 8 bytes have been written so far.
