/*
* This implementation consists of four files: kyber.h (header),
* kyber.c (this), kyber-common.c (common part), and kyber-kdep.c
* (KYBER_K dependent part).
*
* It is for inclusion in libgcrypt library. Also, standalone use of
* the implementation is possible. With KYBER_K defined, it can offer
* the variant of that KYBER_K specified. Otherwise, three variants
* are offered.
*
* From original code, following modification was made.
*
* - C++ style comments are changed to C-style.
*
* - No use of KYBER_NAMESPACE and FIPS202_NAMESPACE. Don't export
* internal symbols.
*
* - "verify" routine is changed to return 1 on success, and now has
* new name "verify1", so that the use of the routine won't need
* negation (since negation might result non-constant-time code with
* branch by some compiler).
*
* - For "xof" routines, definitions of xof_init and xof_close are
* added, so that memory will be possible to be cleared after its
* use.
*
* - Different external API for shake128, having _init and _close.
*
* - New implementation of kyber_shake128_absorb, with the shake128
* API.
*
* - Added an external function: shake256v with variable arguments.
*
* - Macro definitions of xof_squeezeblocks, prf, and rkprf are
* modified to use the shake128 API and the shake256v function.

* / :: Switch to opaque format.
* & :: Switch to buffer descriptor mode - see below.
* ? :: The previous parameter is optional.
*
* In general parameter names are single letters. To use a string for
* a parameter name, enclose the name in single quotes.
*
* Unless in gcry_buffer_t mode for each parameter name a pointer to
* an MPI variable is expected that must be set to NULL prior to
* invoking this function, and finally a NULL is expected. Example:
*
* _gcry_sexp_extract_param (key, NULL, "n/x+ed",
* &mpi_n, &mpi_x, &mpi_e, NULL)
*
* This stores the parameter "N" from KEY as an unsigned MPI into
* MPI_N, the parameter "X" as an opaque MPI into MPI_X, and the
* parameter "E" again as an unsigned MPI into MPI_E.
*
* If in buffer descriptor mode a pointer to gcry_buffer_t descriptor
* is expected instead of a pointer to an MPI. The caller may use two
* different operation modes: If the DATA field of the provided buffer
* descriptor is NULL, the function allocates a new buffer and stores
* it at DATA; the other fields are set accordingly with OFF being 0.
* If DATA is not NULL, the function assumes that DATA, SIZE, and OFF
* describe a buffer where to but the data; on return the LEN field
* receives the number of bytes copied to that buffer; if the buffer
* is too small, the function immediately returns with an error code
* (and LEN set to 0).
*
* PATH is an optional string used to locate a token. The exclamation
* mark separated tokens are used to via gcry_sexp_find_token to find
* a start point inside SEXP.
*
* The function returns 0 on success. On error an error code is
* returned, all passed MPIs that might have been allocated up to this
* point are deallocated and set to NULL, and all passed buffers are
* either truncated if the caller supplied the buffer, or deallocated
* if the function allocated the buffer.
