In order to store passwords in cryptographically hashed form, we need to prevent small uncertainties in the click points from ... WebNov 12, 2013 · There is a misconception that layering different crypto practices results in something that is more secure than any individual practice on its own. However that's rarely the case. Properly implemented password hashing with a long salt is cryptographically secure. The purpose of hashing and salting passwords is protecting the data at rest.
