cl_verify - Check whether key and lock strings match with libcanlock

       Dennis Preiser
       (Based in part on the implementation from G. J. Andruk for Version 2)

       The base64 implementation is written by Kungliga  Tekniska  Hogskolan  (Royal  Institute  of  Technology,
       Stockholm, Sweden)

       The hash algorithms are implemented with code from RFC 6234

       The  cl_verify()  function checks whether a <c-key-string> and a <c-lock-string> element according to RFC
       8315 matches or not.

       The hash algorithm for <scheme> is selected with hash.

       The  <c-key-string>  element  is  specified  with  c_key_string  and  the  <c-lock-string>  element  with
       c_lock_string.

       The  function  cl_split() can be used to extract <c-key-string> from <c-key> (or <c-lock-string> from <c-
       lock> respectively) elements.

       Consider the function cl_verify_multi() to check multiple keys against multiple locks.

       Upon successful completion zero is returned.
       All other values indicate an error.

libcanlock tries to comply with the following standards:

       RFC 5537, RFC 6234, RFC 8315

#include<libcanlock-3/canlock.h>intcl_verify(cl_hash_versionhash,constchar*c_key_string,constchar*c_lock_string);

       Supported values for hash (by version 3.0.0 of libcanlock):
       CL_SHA1 CL_SHA224 CL_SHA256 CL_SHA384 CL_SHA512
