What is a Hasher?
The Hasher, also known as just a 'Hash', is your only defense against brute-force (Cracker) attacks. The higher your Hasher level, the less chance you have of getting hacked. If you have been hacked, however, either your Firewall or your Hasher is not good enough.
For example; Your Hasher is at level 30.0. Your attacker has a Cracker that's level 30.1. Therefore, he/she wins and hacks into you. Vice versa, if you have a higher Hasher than his/her Cracker, then he/she cannot hack you.
Where can I get the Hasher?
You should already have one, but in the instance that you don't, simply head on over to the Download Center and download it from there. Logs are not recorded, so don't worry about clearing them.
How do I research my Hasher?
To research a piece of Software, head to the University tab on your side-menu, then from there select the piece of Software you wish to research. Follow through and research the Software.
It says I have no software to research!
This is because you have not bought the License.
Alternatively, you can go into your Software tab on the side-menu, and click the little blue circle icon that's located next to the Software's name. From there, you can buy the license, (If you haven't already), and research the software following the steps I have provided above.
