The GNULIB, contains even more HMAC based algorithms, c.f. https://www.gnu.org/software/gnulib/MODULES.html#module=crypto/hmac-md5 so a future project might be including these algorithms as well, adding a third key input parameter. There is also a GNULIB "high-level" interface to Libcrypt. It might be easier to use, but it introduces a new build dependency, so better stick to the "low-level" functions for now. */ #if defined (HAVE_CONFIG_H) # include "config.h" #endif #include <string> #include "lo-hash.h" #include "defun.h" #include "error.h" #include "ov.h" #include "ovl.h" OCTAVE_NAMESPACE_BEGIN DEFUN (hash, args, , doc: /* -*- texinfo -*- @deftypefn {} {} hash (@var{hfun}, @var{str}) Calculate the hash value of the string @var{str} using the hash function @var{hfun}.
