         The params argument is an argv-like null-terminated vector of type char
         *. The first element of params represents the mechanism token name from
         crypt.conf(4). The remaining elements of params represent strings of
         the form <parameter>[=<value>] to allow passing in additional
!        information from the crypt.conf entry, such as specifing rounds
         information "rounds=4096".
  
  
         The crypt_genhash_impl() function must not free(3C) ctbufflen on error.
