NAME

       cl_verify_multi - Check multiple keys against multiple locks with libcanlock

SYNOPSIS

       #include <libcanlock-3/canlock.h>

       int cl_verify_multi(cl_hash_version *rejected_hash_list,
                           const char *c_key_list,
                           const char *c_lock_list);

       Supported values for reject_hash (by version 3.3.0 of libcanlock):
       CL_SHA1 CL_SHA224 CL_SHA256 CL_SHA384 CL_SHA512

DESCRIPTION

       Attention: This function is not available with versions before 3.3.0.

       The  cl_verify_multi()  function  checks  a list of <c-key> elements against a list of <c-
       lock> elements according to the algorithm defined by RFC 8315 in Section 3.5.

       Hash  algorithms  for  <scheme>  that  should  be   rejected   can   be   specified   with
       rejected_hash_list.   Specify  either  NULL,  to  accept  all hash algorithms supported by
       libcanlock, or a pointer to an array terminated with CL_INVALID.
       A reject list is used instead  of  an  accept  list  so  that  programs  using  libcanlock
       automatically  inherit  support  for  stronger  hash  algorithms  that may be added in the
       future.

       The <c-key> elements must be specified with c_key_list and the and <c-lock> elements  with
       c_lock_list.   Both  must be strings where the elements are separated by single SP (space)
       characters.
       The output of  the  header  field  parser  canlock-hfp  is  suitable  for  c_key_list  and
       c_lock_list.   The function cl_hp_parse_field() from the libcanlock-hp library can be used
       to execute the parser.

RETURN VALUE

       If one of the keys matches one of the locks, zero is returned.
       All other values indicate an error.
