NAME

       kcapi_md_setkey - set the key for the message digest handle

SYNOPSIS

       int kcapi_md_setkey(struct kcapi_handle * handle, const uint8_t * key, uint32_t keylen);

ARGUMENTS

       handle
           [in] cipher handle

       key
           [in] key buffer

       keylen
           [in] length of key buffer

DESCRIPTION

       With this function, the caller sets the key for subsequent hashing operations. This call
       is applicable for keyed message digests.

       After the caller provided the key, the caller may securely destroy the key as it is now
       maintained by the kernel.

       return 0 upon success; a negative errno-style error code if an error occurred
