Key finding

Learn more about the complex world of data security with a clear understanding of two crucial techniques: password hashing and salting: why these methods are more than just technical gobbledygook, but important building blocks for securing your online accounts.

In an increasingly networked world, it is no longer enough to simply store or encrypt passwords. Cyber criminals are constantly developing new methods to access sensitive data - which is why stronger protection mechanisms are needed. Password hashing and salting are among the most effective methods for effectively protecting your access data from misuse. In this article, we explain how these technologies work - and why they should be standard in any secure IT infrastructure today.
