crypto_shash_descsize() returns the size of the shash_desc context needed to compute the hash, not the size of the hash itself. crypto_shash_digestsize() would be correct, or alternatively using c->hash_len and c->hmac_desc_len which already store the correct values. But actually it's simpler to just use stack arrays, so do that instead.
