NAME

       shishi_checksum - API function

SYNOPSIS

       #include <shishi.h>

       int  shishi_checksum(Shishi * handle, Shishi_key * key, int keyusage, int cksumtype, const
       char * in, size_t inlen, char ** out, size_t * outlen);

ARGUMENTS

       Shishi * handle
                   shishi handle as allocated by shishi_init().

       Shishi_key * key
                   key to compute checksum with.

       int keyusage
                   integer specifying what this key is used for.

       int cksumtype
                   the checksum algorithm to use.

       const char * in
                   input array with data to integrity protect.

       size_t inlen
                   size of input array with data to integrity protect.

       char ** out output array with newly allocated integrity protected data.

       size_t * outlen
                   output variable with length of output array with checksum.

DESCRIPTION

       Integrity protect data using key, possibly altered by supplied key usage.  If key usage is
       0, no key derivation is used.  The OUT buffer must be deallocated by the caller.

RETURN VALUE

       Returns SHISHI_OK iff successful.
