NAME

       cl_split - Split Cancel-Key or Cancel-Lock with libcanlock

SYNOPSIS

       #include <libcanlock-3/canlock.h>

       cl_hash_version cl_split(char *input, char **klstring);

       Possible return values (by version 3.0.0 of libcanlock):
       CL_INVALID CL_SHA1 CL_SHA224 CL_SHA256 CL_SHA384 CL_SHA512

DESCRIPTION

       The cl_split() function splits a <c-key> or <c-lock> element according to RFC 8315.

       The  hash algorithm for <scheme> is extracted and the corresponding ID is returned. If the
       hash algorithm is not found or not supported, CL_INVALID is returned.

       A pointer to the <c-key-string> or <c-lock-string>  element  respectively  is  written  to
       klstring  on success (points inside the string input and therefore no additional memory is
       allocated).
       NULL is written to klstring on error.

RETURN VALUE

       Hash algorithm ID (CL_INVALID on error).
