This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information. If you get incorrect false responses from password_verify when manually including the hash variable (eg.

for testing) and you know it should be correct, make sure you are enclosing the hash variable in single quotes (') and not double quotes (").

Detecting attempts to find these weaknesses is a critical protection mechanism.

These definitions are used within this document: Ensure that data is not only validated, but business rule correct.

However, simply preventing attacks is not enough - you must perform Intrusion Detection in your applications.

Otherwise, you are allowing attackers to repeatedly attack your application until they find a vulnerability that you haven't protected against.

The idea is that you should check that the data is one of a set of tightly constrained known good values. Data should be: This strategy, also known as "negative" or "blacklist" validation is a weak alternative to positive validation.

Essentially, if you don't expect to see characters such as ?

In many cases, Encoding has the potential to defuse attacks that rely on lack of input validation.

For example, if you use HTML entity encoding on user input before it is sent to a browser, it will prevent most XSS attacks.

This is not to say that the entire set of business rules need be applied - it means that the fundamentals are performed to prevent unnecessary round trips to the backend and to prevent the backend from receiving most tampered data.
