For example, it is easy to find collisions and second preimages for your hash function if the input is allowed to be longer than 24 bytes, because only the … WebHashing is a one-way function (i.e., it is impossible to "decrypt" a hash and obtain the original plaintext value). Hashing is appropriate for password validation. Even if an attacker obtains the hashed password, they cannot enter it into an application's password field and log in as the victim.
