WebDec 5, 2016 · The cryptographic process which uses hashes and secret keys is signing data. Here you create a hash of your data and a MAC (message authentication code) based on public/private key cryptography using the private key. A hash tells you only that data was modified or not. A MAC uses any kind of secret, thus it protects also against manipulation. WebAlthough it is not possible to "decrypt" password hashes to obtain the original passwords, it is possible to "crack" the hashes in some circumstances. The basic steps are: Select a password you think the victim has chosen (e.g. password1!) Calculate the hash. Compare the hash you calculated to the hash of the victim.
