| atomic.h |
Simple helper class to expand std::atomic with copy constructor and copy
assignment operator, i.e. for use as element in a container like
std::vector. The construction of instances of this wrapper is NOT atomic
and needs to be properly guarded.

Generic XMSS Address type holding 256 Bits of data. Properties
of all three address formats L-Tree-Address, Hash-Tree-Address,
OTS-Hash-Address can be called depending on the type currently
assigned to the XMSS address using set_type().

The code requires sizeof(size_t) >= ceil(tree_height / 8)
Maximum supported tree height is 20, ceil(20/8) == 3, so 4 byte
size_t is sufficient for all defined parameters, or even a
(hypothetical) tree height 32, which would be extremely slow to
compute.

| xmss_wots.cpp |
Algorithm 2: Chaining Function.
Takes an n-byte input string and transforms it into a the function
result iterating the cryptographic hash function "F" steps times on
the input x using the outputs of the PRNG "G".
This overload is used in multithreaded scenarios, where it is
required to provide seperate instances of XMSS_Hash to each
thread.
@param params The WOTS parameters to use
@param[out] result An n-byte input string, that will be transformed into
the chaining function result.
@param start_idx The start index.
@param steps A number of steps.
@param adrs An OTS Hash Address.
@param seed A seed.
@param hash Instance of XMSS_Hash, that may only by the thread
executing chain.
