Remembering HMAC-SHA-1 (secret key, data) is sufficient to verify the integrity of the data without allowing entities that don't know the key to find what the data is. Even SHA-1 (data) would mostly do for this, except that an adversary could verify a guess for the data. dan brown angels and demons download https://styleskart.org
