Looking for real good software for iMac to encrypt all key strokes. Online a lot ! Thanks

Test your system's FIREWALL, by going to the following link and running the TEST. Make sure to select ALL SERVICE PORTS.

This is how my computer did...

What did your TEST say? Make sure to cover your IP ADDRESS, if you are going to post a picture, like I did.

Was the friend, perchance, on a PC? "To understand how KeyScrambler works, it helps to look briefly at how an operating system like Windows actually processes keystroke data." - http://www.techrepublic.com/blog/security/keyscrambler-how-keystroke-encryption- works-to-thwart-keylogging-threats/4648

Do you have reason to suspect you have keylogging software running on your computer? If you do, you have a bigger general computer security issue because your security would be so lax you could have all kinds of things on it. I mean, we're talking you downloading malware left, right, and center from unscrupulous web sites and allowing them to install it on your computer. Basically a Mac equivalent of a PC user running their computer for the past 5 years without any virus protection. If things are that bad then you're famous because I have never heard of a Mac user who has things going to that extent. I'm not sure if I could do that to my computer if I even tried. 🙂

Hello, I don't think you can encrypt "keystrokes" per se, what exactly is it you want to prevent?

Interesting, thanks Limnos! 🙂

Besides checking for Key Loggers, probably your best defence is...

Little Snitch, stops/alerts outgoing stuff...

I'd avoid Filevault by miles, unless you think your iMac is going to get stolen someday.
