PHP / Security One of the many ways of hashing data using PHP is a function called md5(). md5() converts a string of text into a 32-character hash, using a secret algorithm, thus protecting the original source information. md5() hashed strings cannot be dehashed either, which presents us with the novel problem of working out if two md5-hashed strings are equal. The answer is actually quite simple. Take a login system - instead of dehashing the string and comparing it to a regular password, you take the hashed string and compare it to a string that has already been hashed! Sounds simple doesn't it? Site: biorust.com
