WebJan 3, 2024 · Usually, data is hashed at a certain time and the hash value is protected in some way. At a later time, the data can be hashed again and compared to the protected value. If the hash values match, the data has not been altered. If the values do not match, the data has been corrupted. WebFor password-hashing, you should not use a normal cryptographic hash, but something made specially to protect passwords, like bcrypt. See How to safely store a password for details (this article advocates the use of bcrypt)..
