I'd suggest not to define a separate hmac_set_key_expanded().
Will the folllowing function work for you?
static nettle_set_key_func hmac_md5_set_key_wrapper
static void
hmac_md5_set_key_wrapper(void *ctx, const uint8_t *key)
{
hmac_md5_set_key(ctx, MD5_BLOCK_SIZE, key);
}
It will be less intrusive and more in line with other set_key wrappers.
