NAME

cl_verify - Check whether key and lock strings match with libcanlock

#include <libcanlock-3/canlock.h>

int cl_verify(cl_hash_version hash,
              const char *c_key, const char *c_lock);

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

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 and the <c-lock-string> element with c_lock

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

The hash algorithms are implemented with code from RFC 6234
