What this prevents is a hacker getting (or generating) a table of checksums for every 1-8 digit password and learning 40% of your users' logins from ONE operation. Instead he has to generate this table once per password. – Glitch Desire Aug 6, 2013 at 16:44 1
WebPlain MD5 is actually one of the worst and unsecure way to store passwords, just after plaintext of course. If you actually store MD5 on your database, and don't want to recode your password scheme to use better password hashing techniques, you can add a salt. The salt is a random string that will be added to the user's password. WebAug 7, 2015 · Also unlike secret-key encryption, the salt does not need to remain secret; it merely needs to be unique per user. The purpose of a unique salt per user is to thwart pre-computation and to make brute-force guessing passwords from a list of hashes more expensive. Can I encrypt my (bcrypt) password hashes? Yes.
WebJun 3, 2016 · MD5 isn't encryption. It's a one-way cryptographic hash function. With enough compute power and/or storage you can brute force md5 to figure out what the plaintext might have been but it's only one possible plaintext for that hash. It's designed to be both slow and difficult to reverse, and impossible to reverse 1:1. There are known MD5 collisions.
