libcanlock(3) libcanlock 3.3.2 manual libcanlock(3) NAME cl_verify - Check whether key and lock strings match with libcanlock SYNOPSIS #include <libcanlock-3/canlock.h> int cl_verify(cl_hash_version hash, const char *c_key_string, const char *c_lock_string); Supported values for hash (by version 3.0.0 of libcanlock): CL_SHA1 CL_SHA224 CL_SHA256 CL_SHA384 CL_SHA512 DESCRIPTION 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 mul- tiple locks. RETURN VALUE Upon successful completion zero is returned. All other values indicate an error. AUTHORS 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 REPORTING BUGS Report bugs to <mailto:michael.baeuerle@gmx.net>.
