NAME

       shishi_verify - API function

SYNOPSIS

       #include <shishi.h>

       int  shishi_verify(Shishi  *  handle, Shishi_key * key, int keyusage, int cksumtype, const
       char * in, size_t inlen, const char * cksum, size_t cksumlen);

ARGUMENTS

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

       Shishi_key * key
                   key to verify 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 that was integrity protected.

       size_t inlen
                   size of input array with data that was integrity protected.

       const char * cksum
                   input array with alleged checksum of data.

       size_t cksumlen
                   size of input array with alleged checksum of data.

DESCRIPTION

       Verify checksum of data using key, possibly altered by supplied key usage.  If  key  usage
       is 0, no key derivation is used.

RETURN VALUE

       Returns SHISHI_OK iff successful.
