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. WebThe salt is any any two characters which are to be subsequently used as part of the encryption's algorithm.
